Heavy weight drill pipes we produce are integral. Materials are from AISI 4145H modified drill collar material. Hardbanding on both end and center of the body increases abrasion resistance and extend service life. Heavy weight drill pipe is developed to provide a gradual transition from drill collars to the relatively light weight drill pipe. It can reduce fatigue damage to the drill pipes. Heavy weight drill pipe is intended primarily for directional drilling. It improves directional co...

Shenlong integral stabilizers are manufactured from singer bar of AISI series 4145 H professional-forged steel. The blades are formed by spiral milling operation that removes metal between the blades, thus leaving the blades as an "integral" part of tool. And are spiraled to give a maximum continuous wall contact and to minimize rotating torque and damage to the wall of the hole. Shenlong employs "pressed in" tungsten carbide alloy button. Strict ultrasonic inspections have been applied to all...

We offer square and hexagonal kellys. Kellys are available up to 14m long. Our kellys are made from AISI 4145H modified alloy bars that are quenched and tempered full length. A hardness range of 285 to 341 BHN and a minimum impact value of 54 joules as per ASTM A 370 BHN chirpy are maintained one inch bellow the surface at room temperature. All ends and center drive section-trepanned to provide true bores. To improve resistance to galling. all connections are phosphatized and coated with API thr...
