Precision hydraulic seamless steel pipe, cold-drawn precision hydraulic seamless steel pipe, cold-drawn black phosphated hydraulic seamless steel pipe, high-precision white galvanized hydraulic steel pipe. Precision hydraulic seamless steel pipes have superior mechanical properties. The salient features of steel pipes are high precision and high finish. Due to the special bright heat treatment process, the inner and outer walls of the steel pipe will not produce oxide layers after heat treatment, and the inner and outer walls of the steel pipe have high cleanliness; the mechanical process performance of the steel pipe is excellent, and the steel pipe can withstand high pressure and no leakage under various use environments. Deformation, flaring, flattening and no cracks. After the inner hole and surface are phosphated and antirust treated, they can be installed directly without pickling and rust removal, etc., which saves time for our customers and improves work efficiency. Precision hydraulic seamless steel pipes are widely used in injection molding machines, hydraulic presses, shoe-making machinery, hydraulic equipment, high-pressure tubing, ferrule (steel pipe) joint connections, rubber machinery, forging machinery, die-casting machines, engineering machinery, sanitation vehicles, automobiles Industry, shipbuilding industry, metal processing, military industry, diesel engines, internal combustion engines, air compressors, construction machinery, marine equipment (CCS certification), metallurgical equipment, agricultural and forestry machinery, etc., and have established a good reputation in various industries.
