The drill pipe produced by our company is made of high-end technology. The steel of drill pipe body and joint is selected with high quality materials. Meanwhile, metallurgical technology is strictly controlled to increase hardenability of steel and ensure uniform microstructure and mechanical properties and good weldability. Ensure uniform and uniform hardness, increase the toughness of the material and improve the fracture toughness of the steel. Thus, the performance stability of the drill pipe is improved and the consumption of drill rod is reduced, which provides convenience for the majority of customers. Get the approval of the vast number of customers.
