Durability and mechanical properties is very important for the construction. It is responsible for most of the drilling process, and also the most expensive consumable. Chinastar drill pipes is torsion resistance\bending resistance\ tensile resistance, and it has high quality, high durability and high reliability. Its research development and manufacturing become the leader of the industry.

Our company's drill pipe materials are purchased from baosteel, hengyang steel, tianjin big seamless steel mills etc. Domestic first-class steel mill and the world famous Japanese sumitomo metal industry company.
Upsetting and heat treatment of drill pipe body\machining operation of tool joint\friction welding assembly and all kinds of production and inspection are completely done in our company.
