Factory Making Gasoline Engine Water Pump - Drill Collar-Slick and Spiral Downhole Pipe – VS Detail:
The drill collar is made from AISI 4145H or finish rolling structural alloy steel, processed as per API SPEC 7 standard.
In the entire producing process of drill collar, the test data of each item’s performance test, from workblank, heat treatment to connecting thread and other manufacturing process, are traceable.
Drill collars’ detection is completely as per API standard.
All the threads undergo phosphatization or copper plating treatment so as to increase their corrosion resistance and avoid tool threads’ thread gluing phenomenon.
