WELCOME TO CSST The drill pipes produced by our company are processed from the materials produced by domestic well-known large iron and steel enterprises (Angang and Baosteel, etc.). The heat treatment of the materials is processed by an integrated multi-purpose furnace. All threads are processed by professional NC. All threads are equipped with thread gauges in line with international standards, with internal thickening treatment and tempering treatment after friction welding. Therefore, the quality of the processed drill pipe is stable and reliable, and the service cycle is greatly prolonged. We can not only process API standard threaded drill pipes with different lengths, diameters, wall thicknesses and materials, but also customize the drill pipes according to the materials, lengths, wall thicknesses and threads required by customers.
