Features

Integral heavy weight drill pipe are made of AISI 4142H - 4145H alloy structural steel. Production complies

with the provisions under the Standard SY/T 5146-1997. Connector screws comply with the provisions of the

Standard API SPEC 7-1. Heavyweight drill pipe is a kind of drilling tool of medium weight which is similar to

the drilling rod. Its wall thickness is greater than that of the drill rod but smaller than that of the drill collar.

The prolonged tool joint is linked to the pipe with thick walls. Generally, it is placed between the drill rod and

the drill collar during the formation of the drilling string to prevent the unexpected change in the section of

the drill string and reduce fatigue of the drill rod. It can be used for directional well drilling, to work quickly

when the torque is rather low in order to cut wear and damage of drilling string. As its steel performance is

lower than that of the drill collar and the contact area on the well wall is small, differential pressure jamming

is rare.

Drill collar data

Slick Drill Collar

A drill collar is made of structure steel alloy forged or rolled from AISI 4145H. Processing and thermal

treatment of deep-holes.

The drill collar is processed and made as per Standard API SPEC 7-1. Thermal treatment is conducted over

the whole length of the products to ensure that its mechanic performance can meet the provisions under

the Standard API SPEC 7-1. Its Brinell hardness ranges between 285 and 341. And impact energy of its

Charpy V-shaped notch can be 40 ft-lb at a temperature below the surface of the pipe.

Traceability: During the entire process of the making of a drill collar, complete data from performance

tests for the processing of each part including roughcast, thermal treatment and connecting thread will

be kept for reference. A separate number will be affixed to each single part.

Required testing procedures:

All the drill collars will be tested according to the API Standard. Testing of surface dimensions and

ultrasonic wave and magnetic particle testing over the whole length of a product will be included.

Cold forming of thread bases: Cold rolling must be done for the bolt root and elevator recess of a drill

collar. Thus, the bearing capacity of the upper radius will be increased via reducing crack diffusion to

increase fatigue strength of a drill collar and extend the service life.

Phosphating or brass plating: Phosphating or brass plating will be conducted for all screw threads to

increase their corrosion resistance and avoid thread jamming of drilling tools.

Dimensions for slip, elevator groove and elevator through-holes of the drill collar (API RP 7G)

Our company may, as per users' requirements, process slips and elevator grooves on drill collars. Hoisting

joints and safety grips are not required for the grooves to ensure safety during operations. The

dimensions and shapes of the slips and elevator grooves all comply with the provisions under the Code

API RP 7G.

Screw thread protector: Our company may, as per users' requirements, provide steel or plastic-steel ring

thread protectors (thread protector) for our products.

Rontech uses only the best material of 4145H from the best Chinese supplier Xingcheng Special Steel.

Spiral drill collar

Spiral drill collar are a kind of petroleum drilling tool series of our company. This kind of drill collar is

capable of preventing differential pressure detention of tools during drilling. Spiral grooves will enable

the mud to flow freely around the drill collar to use balance pressure to prevent the formation of

obstruction so as to effectively prevent differential pressure jamming. The contact area against the wall

of the well can be cut so as to effectively reduce the possibility of forming differential pressure

obstruction.

Spiral grooves will enable the mud to flow freely around the drill collar to use balance pressure to prevent

the formation of obstruction so as to effectively prevent differential pressure jamming. The contact area

against the wall of the well can be cut so as to effectively reduce the possibility of forming differential

pressure obstruction.

The extensive use of spiral drill collar is based on its characteristics. This special drill collar is able to

reduce the contact area between the well wall and the pipe so as to avoid "rock-drilling jamming"of the

drill string.

The weight of spiral drill collar is 4-6% less than that of the round drill collar.
