In a gradually developed intermediate weight, with a wall thickness between pipe and collar, the pipes are used as a kind of drill tool between pipe and collar with a gradual change of section plane to reduce drilling fatigue to prevent stress concentration at the top of the drill collars. It also allows you to drill at high speed with a reducing torture in case of different pressure sticking during directional well drilling works. Because of its relatively low steel strength, it reduces directional resisting and minimizes contact fatigue, both of which are common problems in large angle or horizontal drilling. The reduced number of pipe failures and increased drill pipe life also make it appropriate for some straight hole�s drilling. Integral heavy weights drill pipes Size Outside Dia. Inside Dia.

Tri-spiral heavy weight drill pipe features will make less contact with the well wall, therefore it has greater ability in drill-pipe-sticking prevention and better auto-cleaning characteristics than standard heavy weight drill pipe, and provides optimum performance in severe drilling conditions. Tri-spiral heavy weight drill pipe is designed to deliver the maximum stress to the drilling bit, so as to save time and reduce drilling cost, especially in pliable and tough drilling conditions. Kellys Our company offers square and hexagonal kellys. Kellys are available up to 46 feet long. Our kellys are made from 4145H modified alloy bars which are quenched and tempered in the full processing course. A hardness range of 285 to 341 BHN and a minimum impact value of 40ft-lbs are maintained one inch below the surface at room temperature. All ends and center drive sections trepanned to provide precise bores. They are drifted to API specifications, and all connections are machined. Kellys are all stamped with the API monogram.

Processing and thermal treatment of the pipe hole The drill collar are trepanned and drifted to API Spec 7. Grinding crafts adopted finish boring technology eliminates regions of the weld stress concentration, making welding appearance more perfect, and increasing their life. The full length thermal treatment ensure the mechanical performance fullfil even exceed API Spec 7 requirements. Its brinell hardness ranges from 285 to 341, moreover, charpy �v� notch minimum impact strength of 40 ft-lb at 70� are guaranteed one inch below the surface. Traceability From receipt of mill�s certified raw material to the completion of all the processing, in each process of which complete traceablity mechanism workcraft. Serial numbers are die stamped on bar bodies. Routine and strict inspection procedures All our drill collars are inspected to comply with the API standards. These inspections include fluorescent magnetic-particle detection and inner ultrasonic flaw detection and hardness detection over the entire body of the drill collar as well as other mechanical performance detection. Cold rolling process The thread roots, as well as the elevator recess, shall be cold-rolled. Cold rolling creates such a compressive upper radius stress that increases fatigue resistance by minimizing crack initiation. Phosphate-coated or copper plating All connections shall undergo phosphate-coated or copper plating process to ensure corrosion resistance, so as to avoid galled thread. Slip groove, elevator groove and size Our company offers optional slip and elevate and accepts reprocesses orders, improving the handling efficiency and guarantee safety. Unless special specification is required, slip and elevator are processed in compliance with API rp 7G guidelines.

Spiral grooves make mud circulate freely around the drill collar to equalize pressure for sake of drill pipe sticking. It reduces the probability of sticking occurrence due to different pressure through reduction of touching area. Spiral drill collar is widely used because of its special structure. The special grooves decrease the volume of the contact with the well wall. It leads to the decrease of the sticking and turning of the drill pipe string. The weight of Spiral drill collar will be reduced approximately 4%-6% by spiral conversion. Inspections for spiral drill collars According to API SPEC, each collar undergoes inspections, including thread fluorescent magnetic-particle detection and full-length ultrasonic flaw detection and to ensure the quality Non-magnetic drill collars Non-magnetic drill collar adopts a kind of chrome manganese alloy steel as material, low carbon obtained by combining a proprietary chemical analysis and rotary hammer process. The material is resistant to corrosion crack, with low magnetic conductivity, with no tendency to galling and high wearproof performances.
