International Standard HDD Drill Pipe Stainless Steel Forging Processing Type
Description of International Standard HDD Rock Drill Rods Stainless Steel Forging Processing Type
HDD drill rods are all manufactured by CNC machines. They're made of high quality steel with heat-treated.We choose the best steel tubes in the market to manufacture our rods and pipes. Spot check will be conducted after the steel tubes delivered to company. We will make sure the compositions and specifications match the inspection report form the suppliers.
Heat treatment will greatly improve the material strength and increase the thread wear life of the rods and casings. We conduct either tru-wall or both ends heat treatment to the tube body. After heat treatment, strength, hardness, straightness and concentricity of the treated tubes will be tested in our lab.
