Drill pipe

Minimum Order: 0
Quality/Safety Certification: 0.00


drill pipes are in accordance with API 5D. The
material of drill pipe body are chosen by 1&3 group of API 5D.

echnological conditions

Pipe joints and tube body strictly according to the selection criteria,for welding zone work procedure complete on C-132-J Friction welding machine, for welding parts carry on quenching and annealing after welding,hardening and tempering treatment. Each performance index and the specification request must be achieved related standard.
