SCOPE

This procedure describes the steps to be followed in tightening the bolts during the

assembly of 25 to 1400 mm. for Fiberstrong and Wavistrong (FRP) flanges to full-face

steel flange or Fiberstrong and Wavistrong (FRP) flanges to raised face flange using Kroll

& Ziller or Integrated Gasket.

The flanges of diameters 25 to 1400 mm have a flat face.

The gasket used with the flat face flanges is Kroll & Ziller type G-ST-P/S.

2.

PROCEDURE

a) Thoroughly clean the face of the flanges & the gaskets.

b) Inspect the gasket (Kroll & Ziller type) or integrated rubber gasket of valve forany damage. Do not use damaged gasket or integrated rubber gasket of valve.

c) For the flat face flanges, place the gasket in position & hold it in right place by

masking tape. Ensure that the holes of the gasket & the flange are aligned.

d) Place the flange. Make sure that the mating flange is properly supported to avoid

load being transmitted to the fiberglass flange.

e) Insert the flanges bolts.

f) Install washer and apply nut until it is hand tight.

g) Number each bolt starting at the top in a clock-wise direction.

h) Tighten all the bolts at 70% of the recommended torque value as specify in Table

1 depending on its piping class using the diagonally sequence.

i) Tighten all the bolts at 100% of the recommended torque value as shown in

Table 1 using the diagonally sequence for two rounds.

j) Add spacer in case fiberglass flanges is connected to a raised face flange.

Note:

a) Do not over torque the flange bolts. The over torque may cause permanent

damage to fiberglass flanges.

b) In case bolts are not properly lubricated, or when the flange joint is not sealing, it

is allowed to increase the bolt torque value up to a maximum of 150% of the

recommend bolt torque.

c) Do not laminate the flange joint until the original supports are fixed in location

and the full torque is applied to the flanges in order ensure that the GRE/GRV

flanges are stress free.

d) The Table (1) specifies the torque values for flanged connection.

e) Same bolt torque values in Table (1) can be applied for EPDM /Neoprene (FF) gaskets.

f) For more information please see Flange Guidecatalogue.

Fiberstrong & Wavistrong Flange Guide4

1. General

This Flange Guide describes the requirements, needs and methods for the installation of Fiberstrong and Wavistrong fibre-reinforced plastic (FRP) flanges.

To ensure proper installation of FRP flanges, information, guidelines and instructions on drilling dimensions, sealing

material, bellows, spacer rings, flange supports, fasteners and flange assembly are given.

A flanged joint can consist of any combination containing a fixed flange, a stub-end flange or a blind flange. In this

document, fixed flange, stub-end flange and blind flange will be referred to as flange.

The Fiberstrong and Wavistrong flange design for fixed flanges is in line with (i) the design rules for flanged joints as

described in ASME 2010 section X and (ii) the flange rigidity criterion as described in ASME 2010 section VIII, division 2.

Definition of words used in these instructions: The word shall indicates a requirement

The word should indicates a recommendation

2. Product range and flange types

2.1. Product range

This Flange Guide describes the Fiberstrong as well as the Wavistrong flanges.

The standard Fiberstrong flange product range runs from ID 25 to ID 4000 mm and is available in pressure classes PN 4 to

PN 16 bar.

The standard Wavistrong flange product range runs from ID 25 to ID 1800 mm and is available in pressure classes PN 8to PN 50 bar. For the Wavistrong product range reference is made to the Wavistrong Product List.


12/52


5Fiberstrong & Wavistrong Flange Guide

2.2. Flange types

The FPI product range contains various types of flanges, namely fixed flanges,stub-end flanges and blind flanges.

A fixed flange is a flange with an integral hub (see fig. 1). Fiberstrong fixed

flanges are produced using either the filament winding (FW) process or the

contact moulding process (CM). Wavistrong fixed flanges are available as FW

only.

A stub-end flange is an assembly of a FRP stub-end and a loose flange ring.

Stub-end flanges are available in two varieties:

1. Stub-end flanges having a cylindrical shaped internal configuration(see fig. 2), these products are referred to as stub-end flange CB/FL

and are available for the Wavistrong product range only. The flange

ring of those products is available in steel only.

2. Stub-end flanges having a 45 degree conical shaped configuration

(see fig 3), these products are referred to as stub-end flange FL/PL.

The flange ring is available in both FRP and steel.

3. Drilling standards

The product dimensions of Fiberstrong and Wavistrong FRP flanges are defined by, diameter, drilling pattern and pressure

class. The pressure rating is defined by the pressure class of the flange.

This practice deviates from the method as used for steel flange, where flanges are rated by the applicable drilling class.

Fiberstrong and Wavistrong flanges up to and including ID 600 mm are, depending on the pressure class of the product,

available as standard item according drilling standards ASA 150, ASA 300 and PN 10 to PN 63.ASME, AWWA and MSS drilling patterns are described by the ASA drilling pattern.

Other drilling standards (API/JIS/etc.) are non standard but are available upon request.

Fiberstrong and Wavistrong flanges ID 700 mm and above are available as standard item for drilling standards ASA 150

and ASA 300.

Other drilling standards (API/JIS/PN/etc.) are non standard, but are available upon request.

The drilling patterns of the most common drilling standards are given in Annex H.

4. Gasket and O-ring seal

Flanges ID 25 ID 1400 mm should be assembled using FPI recommendedtype rubber gaskets with steel inlay (see fig. 4):

Kroll & Ziller type G-ST-P/K

Kroll & Ziller type G-ST-P/KN

Kroll & Ziller type G-ST-P/S

Kempchen type WG2

Flanges ID 1500 4000 mm, have a grooved face and shall be assembled using a rubber O-ring seal.

The O-ring dimensions are given in Annex C.

The sealing material depends on the transported medium and temperature and shall be specified by the gasket or O-ring

supplier. The hardness of the gasket sealing material shall be of class 70 or 80 5 Shore A.The hardness of the O-ring material shall be of class 70 5 Shore A.

5. Bellows

Rubber bellows are primarily used to reduce loads

and to facilitate removal of pipe sections, valves

or gaskets.

Bellows are also used to absorb noise and

vibration between equipment such as pumps,

condensers and their mating pipe work.Their high flexibility also makes them suitable for

compensating thermal expansions and small

installation misalignments.

Axial and universal bellows are designed to absorb any combination of three basic movements, i.e. axial movement,

lateral deflection and angular rotation. These bellows are non-restrained, therefore to absorb axial forces it shall be

ensured that the mating pipe systems at both sides of the bellow are fixed.

Lateral bellows (see fig. 5) are designed to absorb lateral deflection. Tie rods shall be used on lateral bellows to transfer the

pressure thrust load. Sufficient tie rods shall be used, to prevent local overloading of the FRP flange. Tie rods shall never be

jointed directly to the FRP flange or to the FRP piping systems, as this will create excessive axial loads on the FRP flange. Thebacking flange, which is part of the axial bellow shall be a solid construction, the usage of fish-plates is not allowed.

Hinged bellows or gimbal bellows are designed to absorb angular rotation. Hinged and gimbal bellows are due to their

construction capable in transferring the axial load, therefore tie rods are not required.

Bolt torque values as specified by bellow suppliers might deviate from the torque values as specified in this document. To

prevent overloading of the FRP flange, the torque values specified in chapter 8 shall not be exceeded unless agreed by the

FPI Technical Support team.

The maximum deflection specified by the bellow supllier may not be exceeded.

UV covers should be installed, to protect the rubber of the outdoors installed bellows.

In order to ensure a proper usage of bellows, their selection shall be reviewed by the FPI Technical Support team.

6. Spacer rings

Spacer rings may be used, if FRP flanges are jointed to raised face flanges, in order to create a flat face configuration. Themating flange might have an uneven surface, therefore the thickness of each spacer ring has to be adjusted to its specific

required dimension.

By using the proper spacer ring thickness, local overloading of the FRP flange is prevented and sufficient gasket

compression is obtained.

7. Fasteners

This section gives information about the type, the quality, the thread standard and dimensions of fasteners to be used for

the assembly of a flanged joint.

7.1. Bolts, stud bolts, washers

Flanges are jointed using either bolts or stud bolts. Stud bolts are typically used in case of assembly in limited spaces, or if

long bolt lengths are required.

The bolt sizes accompanying washer shall be used (see Annex B for washer dimensions).

7.2. Fastener quality

Bolts, nuts and washers should be either made of hot dip galvanized steel or

made of stainless steel. For non corrosive environments zinc plated steel

products may be used.The minimum quality of hot dip galvanized and zinc plated steel bolts, nuts and

washers should be of class 8.8 or grade 5. The minimum quality of stainless

steel fasteners should be of class 70. Figures 6 and 7 show the identification

for class 8.8 and for grade 5 bolts.

In case hot dip galvanized or zinc plated steel products are cut to length,

the cut area should be coated to protect it against corrosion.

7.3. Thread standard

The thread standard of the fasteners shall comply with either ISO metric orUnified Thread Standard (UTS). In case of assembly against a component

containing a threaded hole, the bolt size shall match the holes thread.

Metric and UTS bolts and nuts, shall have a coarse pitch; for UTS this is

specified as UNC or NC, for metric this is specified as coarse.

Flanges shall be assembled using the bolt size as specified in Annex H.

7.4. Bolt length

The bolt length definition for two fixed flanges is specified in paragraph 7.4.1 and for two stub-end flanges in paragraph7.4.2. The same method can be followed for the bolt length definition of any flange combination, such as fixed flange to

stub-end flange or combinations containing blinds. The bolt length definition is a recommendation and does not necessarily

have to be followed. The calculated (stud) bolt length needs to be rounded up to the next available bolt length. It is required

that full thread engagement is obtained after the assembly.

In Annex A, a flowchart for bolt selection is given.

In Annex D to Annex G, the flange thicknesses of fixed flanges and assembly lengths of stub-end flanges are given for

standard products. Special products may have different dimensions; for dimensions of special products FPI shall be

contacted.

7.4.1. Bolt length - Fixed flanges

The (stud) bolt length for fixed flanges can be defined using the following

calculation method.

Bolt length:

Lbolt = 2 (TF + TFtol+ w + p) + g + n

Stud bolt length:

8. Bolt torques

The bolts of flange joints shall be tightened using the prescribed bolt torques, which are given in tables 1 and 2.These torque values are applicable for ASA 150, ASA 300 and PN 10 to PN 63 drilling patterns in combination with the

recommended sealing material as specified in chapter 4.

Bolt torques for other drilling patterns (API/JIS/ASA 600/etc) or for gaskets, other than recommended by FPI, including

special gaskets on valves, pumps, etc, might differ from the values given in tables 1 and 2. Recommended bolt torque

values for these applications shall be reviewed on a case-by-case basis by the FPI Technical Support team.

9. Supports

Aboveground pipeline systems are installed using supports.When jointing FRP flanges to heavy equipment such as butterfly valves, it shall be ensured that the load due to the

weight of the equipment is not transferred to the FRP flange. This load shall be limited by proper supporting of the heavy

equipment. The support for heavy equipment should not be connected to the FRP flange.

The Wavistrong Engineering Guide provides information on types of supports and on the support to support spans.

10. Misalignment

Flanges shall be properly aligned and shall not be subjected to any overload

to meet each other.

Flanges are jointed using rubber type sealing elements, small misalignments canbe consumed by the flexibility of the sealing element.

To prevent overloading of a FRP flange, the bolt torques specified in chapter 8

shall not be exceeded.

An example of exceeded flange parallelism is shown in figure 12.

The allowable for flange parallelism is illustrated in figure 13 where the values

for x are defined in table 3.

11. Assembly instruction

This section describes the assembly of a flange joint. To ensure that the performance of the assembled joint complies withthe requirements used for the design, it is essential that all personnel involved in the jointing procedure is familiar with and

fully understands the techniques described in this assembly instruction.

The instruction is as complete as possible. However, it is not possible to describe all circumstances that might be

encountered in the field. Therefore, our experienced supervisors may deviate from the described method, in order to

achieve an optimum solution using the latest techniques and methods.

Besides, our supervisors may be consulted for clarification of statements made in this document and for advice about

specific problems encountered in the field.

11.1. Quality

It is advised that the jointer possesses a valid jointer certificate, issued by the pipe manufacturer or a qualified certifier.

11.2. Health and safety

When working with FRP products, the following safety precautions

shall be taken:

Wear at all time suitable protective clothing

Use Personal Protective Equipment (PPE), such as:- Safety shoes

- Safety glasses

- Working gloves

- Safety helmet (if required by site conditions)

11.3. Tools and consumables

Torque wrench including box spanner

Ring spanner

Bolts, nuts and washers Gasket or O-ring

Lubricant; suitable for nuts and bolts

Brush

11.4. Inspection

All pipes, fittings and components used in the pipeline system shall be inspected

for damages, prior to the actual assembly activity. Rejected items shall be separated and quarantined from undamaged

materials to avoid unintentional use.

Ensure that all the necessary tools and materials are available. Take notice of the safety precautions stated in this document

and those as per site conditions.

Fig. 14. Health and safety

Fig. 15. Material required for

20/52



11.5. Assembly

The following steps shall be followed to ensure proper assembly of a flange joint.

a Determine the assembly sequence, such that flange assembly in limited

spaces will not be blocked by previous assembled components (see fig.

16).

b Flanges shall be properly aligned and shall not be subjected to any

overload to meet each other. When using the recommended sealing

type, then small misalignments can be consumed by the flexibility of the

sealing, the maximum allowed misalignment is defined in chapter 10.

c For stub-end flanges: the loose ring of the stub-end flange shall be

positioned centred on the stub-end, such that there is an even distance

between the outer diameter of the stub-end and the inner diameter of the

loose ring (see fig. 17).

d Bolt holes should be orientated to straddle the centerlines (see fig. 18).

e Clean the flange sealing face and if applicable the O-ring groove.

Ensure that the O-ring or gasket and all bolts, nuts and washers are

clean. Do not use defective material.

f For assembly using an O-ring: position the O-ring in the groove.

When jointing two flanges with an O-ring seal, only one flange shallhave an O-ring groove.

For assembly using a gasket: position the gasket between the two

flanges, ensure that the gasket is centred relative to the internal diameter

of the flange. The gasket can be centred by inserting a number of bolts,

such that the gasket is supported by the bolts. (see fig. 19).

g Lubricate the thread of the bolts (see fig. 20).

Use suitable lubricant for bolts, for example Molykote.

h Insert all bolts in the bolt holes and assemble them using washers

and nuts. Bolts and nuts shall have washers to avoid exceeding the

allowable surface stress on the FRP flange.

i Ensure that the quality identification on bolts and nuts is visible

(see fig. 21).

j First, the bolts and nuts shall be tightened hand tight.

k Next, the bolts and nuts shall be tightened using a torque wrench anda spanner (see fig. 22). Tightening shall be as per the bolt torquing

sequence as described in ASTM D4024 (see fig. 23). Bolts shall be

tightened, following the bolt torque sequence, first up to 60% of the

prescribed torque value and next up to 100% of the prescribed value as

given in tables 1 and 2.

For flanges having more than 20 bolts, similar alternating bolt

tightening sequences shall be used, where required the FPI technical

support team may be contacted.

l Finally, the bolts and nuts shall be tightened clockwise using 100 % ofthe prescribed torque value. This step has to be repeated until all bolts

are assembled at the prescribed torque value.

Annex H. Drilling standards

The following tables provide the dimensions for API 75, API 150, ASA 150, ASA 300, ASA 600, JIS 5K, JIS 10K and PN6 to PN 63 drilling patterns. For diameters ID 3700 mm and above a FPI specific drilling pattern applies, as no standard is

available. The dimensions of the flange outer diameter (DU) and bolt hole (d), can slightly deviate from the values given in

the related drilling standard. Bolt sizes as specified in API, ASME and AWWA have been converted to metric dimensions.
