Running Manual 5

This manual details the recommended practices to aid in the successfulrunning and pulling of the Tenaris family of premium connections. It has beendesigned to provide an insight to avoid the most common causes of pipe andconnection damages resulting from improper planning, incorrect rigoperations, or inappropriate material handling procedures. The followingsections detail the specific practices to be performed in each operation. This isa general manual that must be used together with the specific guidelines ofthe premium connection to be run.

Equipment Preparation

All accessory and backup equipment, such as cross-overs, safety

subs, float equipment and packer assemblies, should be inspected

to ensure they are in proper condition. Since accessories are

obtained from several sources, care should be taken to ensure

they were threaded with the correct connection. Only accessories

threaded by Tenaris or one of their licensed repair shop facilities

should be used.

Slips and Elevators

Either slip or collar type elevators may be used for casing and

tubing strings. The inserts of the slips and slip type elevators

must be clean and sharp. Extra long slips and slip type elevators

shall be used on long and/or heavy strings. lf collar-type elevators

are used, the bearing surface shall be carefully inspected to

ensure a smooth flat bearing contact perpendicular to the pulling

direction. An uneven bearing surface can damage the coupling

and lead to a premature connection failure. Spider and elevator

slips shall be examined to see that all the surfaces contact

the pipe evenly. Uneven contact can dent the pipe or cause excess

slip-cutting.

The use of high-density inserts is recommended for critical

service materials.

Safety Clamps

The safety clamp is used to suspend the column in case of

insufficient grip by the elevator. The safety clamp must be used

during the running of the first tubing and casing

connections and during the pulling out of the last tubing

and casing connection. Its condition should be

inspected and worn parts replaced at the beginning of

each operation.

Strap Wrenches

When making up corrosion resistant alloys (CRA)

pipes, strap wrenches should be used after stabbing to

make the pin up to the hand tight position or at

minimum until a secure thread start has been achieved.

All straps should be checked prior to start-up to ensure

their proper diameter capability and their cleanness.

Once straps become soiled and begin slipping, they

should be replaced.

Single Joint Compensator

A single joint compensator is recommended to be used

during running and pulling of heavy wall casing and any

CRA tubulars to reduce the compression loads on the

threads that are normally incurred during the stabbing,

make-up and pull out process.

Care must be taken to properly adjust the tension value

of this component prior to the first joint being stabbed.

This will minimize cross-thread damages and galling

during the make-up and break out process.

6 Running Manual

Stabbing Guides

Stabbing guides shall be used to guide the pin into the box and

minimize damage to the connection if the joint is misstabbed.

The stabbing guide must be checked prior to running to ensure

proper fit and condition of the elastomeric inserts.

Handling and Lifting Plugs

Handling plugs are not designed to support more than a single

stand of pipe. Handling plug threads must be cared for and

maintained. Threads should be cleaned, inspected and handled

so as to prevent damage. To ensure proper thread engagement,

both the handling plug and the pipe box threads should be free

of any dirt, paint, and storage compound. Plugs should be

doped and fully made-up by hand, then tightened by pushing it

with a bar. Handling plugs also provide protection of the box

threads from damage by tools or test equipment, which may be

run inside the pipe.

Lifting plugs are designed to support the entire weight of the

string. The lifting plugs must be doped and fully made-up and

power tight to shoulder to achieve full rated lift capacity. Proper

handling practices and sound judgement must be used at all

times to maintain the rated lift capacity of the plug. Damaged

lifting plugs should not be used. At the beginning of each

operations, as well as in case of heavy impact in the lifting plug

throughout the operation, the lifting plug must be inspected

visually and replaced in case of damage.

Power Tongs

The tongs should be in good condition, with jaws that

correctly fit the pipe.

It is recommended to use tongs with back-up. Tongs shall be

equipped with a rotation speed control and should de capable of

operating at a minimum of 3 rpm. It is imperative that the make-

up torque is accurately measured and controlled. Torque

measuring equipment should be in good working order, cover the

appropriate range, and a recent calibration certificate should be

demanded from the power tong contractor prior to starting the job.

When using tongs with built-in back-up, free motion should

be possible between tong and back-up to ensure there is

sufficient travel in the back-up to absorb the make-up loss

and there is sufficient flexibility in the tong/back-up to

compensate for a slight bend and the normal eccentricity

between pin and box.

If a snub line is used, it should be set at a 90-degree angle to

the arm of the tong.

Running Manual 7

Drifting

It is requested that each length of the tubulars (casing, tubing,

accessories) be drifted for its entire length just before running.

Before drifting, make sure that the internal surface is clean and

free from foreign matter that can prevent the correct running

of the drift and can be mixed with make-up compound during

assembly.

If compressed air is available, apply the air jet from box to pin.

The drift shall be handled with care when inserted and when

extracted from the pipe, and drifting should be preferably

performed from the box side to the pin side to avoid damage

on threads, seals and shoulders.

It is recommended to perform drifting while the pipe is on

the rack.

Tubulars that do not pass the drift mandrel shall be

marked with a reject paint band, and laid aside for further

investigation.

For CRA and coated material, it is recommended to use non-

metallic drift or a drift coated with plastic or with Teflon.

Make sure that the drift mandrel OD conforms to the API 5CT

specifications or to the customer´s special drift purchase

specification.

When specified by the purchaser, casing can be "Special Drifted".

Sizes are shown in API RP 5A5 "Recommended Practice for

Thread Inspection of new Casing, Tubing and Plain End Drill

Pipe", or special drift purchase specifications.

Cleaning

It is essential that no hard foreign matter is present on the

threads or seals during make-up.

Cleaning should be performed just before running in the hole

and after drift test, especially in corrosive atmosphere.

Remove threads protectors from pin and box ends.

Clean all thread or storage compounds with any suitable

cleaning process, such as non-metallic bristle brushes and hot

water or a quick-drying solvent-type cleaner (without chlorine).

Do not use diesel or "oily solvent". Use of compressed air is

advisable to dry pin and box.

Check and clean inside the tubulars to eliminate any foreign

material that may fall into the box while stabbing. If

compressed air is available, apply the air jet from box to pin.

The most desirable approach would be to clean the connection

at a temperature above 10°C (50°F) so as to remove all traces of

moisture and/or extraneous matter.

Clean and dry thread protectors.

If running is to be delayed, an application of some corrosion

protection over the threads should be considered. If the

connection is cleaned until twelve hours before the joint is run,

a light oil should be applied by means of a brush or a spray

applicator. If it will be more than twelve hours until a joint is

to be run, some storage compound and clean thread protectors

should be re-applied.

Care must be taken to ensure that the cleaning process does

not cause environmental pollution.

Pipe Length Measurement

The length of each piece of casing and tubing should be

measured prior to running. A calibrated steel tape should

be used. The measurement should be made from the

outermost face of the coupling or box to the outermost

face of the pin nose.

The Effective Length (EL) of each joint is the Total Length

(TL) minus the Make-up loss (ML).

Before the make-up on the rig floor, all threads will be submitted

to visual inspection.

Pipe should be on a rack allowing enough space for 360°

revolution for inspection to assure that each connection is:

• Well cleaned

• Free from rust due to a long and/or incorrect storage

• Free from handling damages

• Free from longitudinal cuts and scratches in the seal area

• Free from burrs or wear

Minor anomalies on thread and torque shoulder surfaces can

be field repaired. Damage on seal surfaces, other than mild

oxidation, is cause for rejection (see Field Repair). After repairing,

threads must be re-cleaned and dried.

Exposed seal surfaces, such as pin nose areas, are particularly

susceptible to handling damage. Special care should be taken

in inspection of these areas for dings, dents, and/or mashed

ends.

Visual Inspection of ThreadsBefore Make-up

Running Manual 9

Field Repair

If necessary, slight thread repairs by # 400 emery cloth or file,

can be performed by Tenaris personnel or by certified personnel

of a thir party company.

Slight repairs can be made only on the thread or on the shoulder

area, but not on the seal area. Only mild oxidation is alloyed to

be removed from the seal by means of a Scotch Brite.

Repairs must not change the shape of the original surface.

When the damages cannot be solved by field repair, the joint

must be rejected.

Field Repair on Coated Pipes

Any damage on the coatings must be repaired either by the

coating company or by certified personnel of a third party

company.

Field Repair on Fiber Glass Lined Pipes

When tubulars with fiber glass lining are to be run, no damages

are allowed to be field repaired.

Installation of Seal Rings

If required by the customer, seal rings can be installed in the mill

prior to application of thread compound and protectors.

Otherwise, seal rings must be securely packaged and forwarded

to a location designated by the customer.

Prior to installation, seal rings identification shall be verified.

Appropriate seal rings shall be obtained through the Tenaris

Licensee Support Group.

Visually inspect the seal ring groove/location for cleanliness.

Remove all grease, oil, metal shavings, or other contaminants

before the installation of a seal ring. Dry the seal ring

groove/location before installing the seal ring.

For seal rings installation, compress the seal ring with the

fingers, so that it partially collapses into the inside diameter of

the pipe. Place the collapsed seal ring into the seal ring groove

and release it. Firmly seat the seal ring into the groove by

applying direct pressure to the face of the ring for the entire

circumference (360 degrees).

A tool to seat the seal ring may be made from a hammer handle,

an axe handle, or other similar device, depending on the OD of

the connection. The end of the tool shall be shaped to contact the

face of the seal ring squarely (metallic tools are not acceptable).

Leverage the tool against the face of the box to apply pressure

to the face of the seal ring.

Seal rings installed in the seal ring grooves shall not protrude

beyond the internal diameter of the coupling or the lining. This

shall be verified with a straight edge placed on the internal

diameter.

If the seal ring pops out of the coupling internal diameter, verify

the seal ring size and seal ring groove dimensions. The seal

rings should be installed shortly before the pipe´s running. Seal

rings and pipes should be aproximately at the same temperature

before installation.

Pipes Lifting from Rack to Rig Floor

During the transportation to the rig floor, the thread protectors

must be kept installed.

For CRA materials, the use of a pick-up/lay-down equipment

with travelling basket coated with rubber or with other soft

materials is requested. Metal to metal contact is not acceptable

for CRA materials.

For standard materials, load and unload using certified textile

slings.

Single joint elevators are recommended for all materials.

On the rig floor, the pipe string shall be sustained by a

device that must not leave incisions or dents on the external

surface of the pipe.

Seal ring (Normal and Collapsed)

10 Running Manual

Operations on the Rig Floor

While the pipe is in the travel basket or laid on the "V" door,

remove the thread protector of the box/coupling, wipe with a

clean cloth the box/coupling or blow it with a jet of compressed

air and apply the proper amount of thread compound as per

pipe manufacturer recommendations.

While the pin is lifted up in vertical position, remove the

protector and wipe the thread with a jet of compressed air.

Inspect the thread to assure that it has not been damaged and

it has been properly cleaned.

Apply the proper amount and type of thread compound as per

the pipe manufacturer recommendations.

Stab the pin into the box of the previous pipe, make them up

and run them into the hole.

Thread Compound Application

Thread storage compound shall be thoroughly removed from

the connection before applying running thread compound.

Apply an even coat of manufacturer recommended

connection thread compound (see Recommended Thread

Running Compound) filling the full thread area and

covering the seal surface and torque shoulder of pin or box

(as per connection manufacturer recommendation). Do

not overdope, the thread pattern should still be evident

after doping.

Running

Dope

Thread

Running Manual 11

Keep the dope well mixed, and stir it very well before using. If the

compound is too thick because of the low external temperature, it

can be warmed up to a maximum of 30°C and mixed up. Never

use oil or solvent to dilute the thread compound.

Keep the dope container covered in order to avoid

contamination from dust, water, or other dangerous elements.

Use new brushes with clean and soft bristle; never use metallic

brushes or spatulas. Use mustache type brush for box end and

plain type bruch for pin end.

Apply thread compound in a continuous film all over the

surface of threads and seals as per the connection manufacturer

recommendations.

When automatic dope applicator is used, try to check the

dope weight sprayed by collecting it and putting it on a

scale. Set up the dope applicator until the minimum weight is

reached. When a brush is used, weigh the minimum

requested quantity of dope with a scale, to have an idea of

the dope volume. Special care should be taken to make sure

that quantity of dope does not exceed the maximum

specified. Excessive thread dope may affect the connection

performance.

Thread Lock Application

When thread lock is required, both pin and box connections

must be cleaned, dried, and free of contaminants. Apply thread

lock compound only on the first two thirds of the pin threads

near the pipe end, excluding the seal area of the pin. A uniform

coat should be applied, a full 360 degrees.

Then, apply thread compound to the internal seal of the box,

covering 360 degrees. The connection shall be made-up as

soon as possible after the thread lock and thread compound

have been applied. A torque in excess of the maximum

make-up torque may be required to shoulder the connections.

Stabbing

Stabbing and initial thread engagement is the most critical

aspect of running premium connections. A stabbing guide shall

be used on the pipe box thread to prevent damage to thread and

seal surfaces. The pipe must be properly positioned and under

complete control before stabbing is conducted. The pipe must

be in true vertical alignment over the box. Movement or sway of

the pipe should be limited to the minimum extent possible.

Personnel on the rig floor and the stabbing board should always

control stability and movement of the pipe. Only after the

pipe is stabilized and properly positioned, lower the pipe slowly

to avoid thread damage. Once the face of the pin is even with

the face of the box, the pin connection should be lowered very

slowly into the box. This process will allow the stab flank of

the pin threads to align with the flank threads of the box and

reduce the possibility of misstabbing, or cross threading.

Thread Engagement

Remove stabbing guide after stabbing. Then rotate the pipe

by hand or manual wrench for a couple of turns. If the

weight of the pipe prohibits turning by hand, turn it very

slowly with tongs (connection should be free running without

torque required) to ensure proper thread engagement. Cross-

threading and misalignment may be corrected now. The

stabber must not rock the pipe during initial stab or make-up.

In case of a misstab, rotating the connection counter-

clockwise 1/4 to 1/2 turns will correct the misalignment and

give proper thread engagement. Re make-up following the

previous indications.

When making up corrosion resistant alloys (CRA) pipes,

strap wrenches should be used after stabbing to make the pin

up to the hand tight position or at minimum until a secure

thread start has been achieved.

Connection Make-up

Power tongs are required. Pipe wrenches, rig tongs or

spinning chain make-up are not recommended. A back-up

tong may

be required until sufficient string weight is developed to

prevent the joint from turning in the slips. Set the power tong

and the back-up tong as close as possible to prevent bending

during make-up. The back-up tong should be of a sufficient

width to prevent crushing the pipe body. Do not set the back-

up tong over the box threads. Do not latch the elevators on

the pipe until the connection is made-up completely.

During power make-up operations, the torque shall be

continuously monitored. The usage of Torque vs Turns make-up

monitoring system with a valid calibration is requested. The

accuracy of turn measurement shall be higher than 1/100 of a

turn. A computer display is required to monitor the make-up, and

shall be capable of printing hard copies of make-up graphs to be

kept on file. A make-up torque graph shall be generated for every

connection. In the event a graph is not produced or is lost, the

connection shall be considered as rejected.

When combining different weights (i.e. 5” x 15 lb/ft with 5” x

18 lb/ft) or different grades (i.e. L80 and P110), use the torque

corresponding to the lightest weight and the lowest grade.

Before starting the running, the equipment must be set up with

the following values provided by the connection manufacturer:

• Minimum make-up torque

• Optimum make-up torque

• Maximum make-up torque

• Minimum shoulder torque

• Maximum shoulder torque

• Reference torque

The initial recommended value for the reference torque is 5%

of the minimum recommended torque. While running, the

reference torque value shall be adjusted to have 1.0 to 1.5 turn

in the display, but it shall remain between 2% to 10% of the

minimum recommended torque.

Make-up Speed

After stabbing, the first 1 or 2 turns must be performed at low

speed to assure proper made-up. Then a higher rotation speed

can be applied, and at the last 1 or 2 turns, the speed must be

reduced again to a low value.

The stabbing operation is particularly critical withhigh alloy steels that have a tendency to gall.

Align the pipe with thecoupling axis

Running Manual 13

When the strings are run by means of automated rigs, the

running procedure varies due to the lack of people

operating around the rotary area. Tongs are remotely

operated from a safe distance from the working area.

Besides the pre-running operations (thread cleaning,

drifting, visual inspection, seal ring installation, pipe length

measurement), the thread compound (or thread lock) must

be applied while joints are on the racks.

After that, the arm of the automatic equipment will

pick each joint up and it will deposit them on the tray to

be transported to the rotary area.

There is no need for performing any manual operation

from this point, as the officer in charge of driving the

automatic equipment will position the pipe in a vertical

way and will make-up the connection according to the

desired rotary speed and torque value.

Running Manual 19

To break out the Tenaris family of premium connections, the

same equipment used to make them up will be required.

If string has been in service for some time, the break-out

torque will likely be higher than the torque required to make-

up the connections.

For coupled connections, the back-up tong should always be

set on the coupling central area during breaking-out, so it is

necessary to prepare the back-up tong die for the coupling size.

Hammering the cupling or connection is not allowed.

Connection Break-out

Backup Tong Position During Break-out

All connections should be broken out and rotated out in low

gear only.

To break-out the connections, unlatch the elevators before

breakout. Locate the connection to be broken out at a

comfortable working height above the slips. Set the power

tong and the backup tong or slips as close as possible to

prevent bending during breakout. Maintain vertical

alignment and control of pipe. This is accomplished by a man

on the stabbing board. Slowly apply the torque required to

break the connection. (Never use a hammer or other hard

object to beat on a connection. The resultant damage could

lead to a failure.) Depending on the torque required, the

upper end of the pipe may start moving. Pipe movement shall

be stopped before additional turning of the connection is

continued.

Maintain a steady, controlled speed until the pin jumps inside

the box. A single joint elevator is recommended to reduce

misalignment during the lifting process. A weight compensator

is recommended to be used to reduce thread galling during

break-out.

Stop rotation immediately when the pin jumps inside the box.

A stabbing guide shall be used prior to lifting the pin out of

the box. The pin must be carefully lifted out of the box to

avoid damage. This is critical on heavy weight pipe or when

pulling double or triple stands. Remove the power tong before

lifting the pin out of the box. Do not lift the exposed pin

threads through the tong. Before moving the pipe further,

protect the threads by installing a clean, dry thread protector

or lift plug as appropriate.

For flush connections, the use of safety clamps is highly

recommended.

Inspection

Once the connection is broken, a brief inspection of seal and

threads of both pin and box should be conducted.

Particular attention must be paid to:

• Seals for evidence of galling

• Threads for evidence of galling

• Pipe for damage caused by power tong or back-up tong dies

• Pipe for damage caused by elevator or slip dies

• Any foreign material in the threads or in the torque

shoulder/seal area of the box member

Re-Running

To re-run a string of Tenaris Premium Connections, the same

procedure as in the initial running should be followed.

20 Running Manual

Running

• Remove thread protectors from pin and coupling ends.

• Clean the connection with a non-metallic bristle brush

and steam or a quick drying solvent type cleaner (without

chlorine).

• Clean and dry thread protectors. Reject damaged

protectors.

• Make sure that the internal surface of the pipes is clean

and free from foreign material.

• Check and clean (by air jet) inside the tubulars to

eliminate any foreign material.

• Pass drift from the coupling or box end to the pin end

avoiding damages on threads and shoulders.

• Tubulars that do not pass the drift mandrel shall be

marked with a reject paint band and laid aside.

• For CRA and coated material, use a non-metallic drift or

a drift coated with plastic or Teflon.

• Measure the Total Length of each piece of casing / tubing /

accessory.

• Calculate the Effective Length of each joint by deducting

the Make-up Loss from the Total Length.

• Visually inspect the connection to assure they are:

- Free from dust due to a long and/or incorrect

storage.

- Free from handling and transport damages.

- Free from burrs or wear.

• Never attempt to repair the seal area of the connections.

• Slight repairs can be made by # 400 emery cloth or file

only on the threads or on the shoulder area.

• After repairing, threads must be cleaned again and dried.

• During pipe moving to the rig floor, thread protectors

must be kept installed.

• Use of weight compensator system is requested, specially

in the case of CRA grades.

Pulling

• Use of weight compensator system is requested, specially

in the case of CRA grades.

• For coupled connections break-out, the back-up tong shall

be set on the coupling middle position.

• The break-out torque will likely be higher than the torque

required to make up the connections.

• All connections should be broken out and rotated out in

low gear only.

• Never use a hammer or other hard object to beat on a

connection.

• Maintain a steady, controlled speed until the pin jumps inside

the coupling (avoid bumping).

• Stop rotation immediately when the pin jumps inside the

coupling.

• A stabbing guide shall be used prior to lifting the pin out of

the coupling.

• The pin must be carefully lifted out of the box avoiding to

damage it.

• Before moving the pipe further, protect the threads by

installing a clean and dry thread protector.

• Once the connection is broken out, a brief visual inspection

of both pin and coupling should be conducted. Particular

attention must be paid to:

- Threads for evidence of galling.

- Pipe body for damages caused by power tong,

backup tong, elevator or slip dies.

- Any foreign material in the threads or in the

torque shoulder of the coupling.

• If the string is pulled out in stands, pin thread protectors

should be on straight and tight.

• Stands should be properly tied with a band to prevent

bending.

Lining ERFV

Seal Ring Flange

For seal ring models always dope the box area between the

seal ring and the shoulder.

Do not apply dopein this area

Apply thread compound only on pin members.

Do not apply thread compound on the protruding nose of the connection.

Never run a pipe with damages in the ERFV lining

Special Care for Connectionswith Seal Ring

When installing seal rings of FGL Models, assure that the seal

ring is properly placed in the space between the flange and the

coupling. Avoid any misalignment.

Special Care for Connectionswith Fiber Glass Lining (FGL)

24 Running Manual

Part A

Part B

Note: Thread compound could be used to cover the seal area

instead of Molykote, in this case a thin, uniform film covering

the seal along the circumference (360°) should be applied. Avoid

doping the small protruding nose outside Part B.

In this case each made up connection must be checked with

a “Teflon drift” to verify the seal ring has not been damaged

during make up.

If pipe or coupling coated area is damaged, it must be repaired

before running the string. This activity can be performed by

the coating company or by authorized and certified personnel

of a third part company.

Torque vs. Turns Monitoring System

For the making up of the Tenaris ER connection the use of a

Torque vs. Turns Monitoring System is not required.

Use Shell HTHP 72732 thread compound for make up. The

use of compound with different properties may result in

low or over torque of the connection, galling and/or leaking.

Environmental friendly compounds may be used with Tenaris

approval.

Apply thread compound only on pin members.

The use of Molykote (Molybdenum disulphide) is recommended

to cover the seal area (Part B). Use the recommended thread

compound to cover the threaded area (Part A).
