API 7-1 Oilfield Drill Collar High-Performance Drill Collar

Drill pipe comply with the provisions under the Standards API SPEC 5DP and API SPEC7. The grade of steel for the drill pipe willbe determined according to the requirements of Group 1 and Group 3 of API SPEC 5DP.(i.e.: Group 1--Grade E; Group 3--Grade X-95, Grade -G-105 and Grade -S-135)As per requirements of customers, drill pipe joints at the same level will be provided, and manufactured drill pipe joints will comply with the provisions under the Standard API SPEC 7-1.

standard heavy weight drill pipe assembly is made up of pin and box tool joints and a heavy weight tube with center upset or wear pad.This configuration helps to prevent stress concentration which could otherwise occur and allows directional drilling with controlled torque and reduce differential pressure sticking.The service life of the HWDP is extended to maximize your investment by; • Providing extra‑long tool joint that increases tong space which allows more connection recuts. • Reducing wear rate on tube OD through additional protection by the center upset or wear pad which keep the tube away from the hole.
