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.
