Precision Rolling Steel Tube Pipe

Product Description

Shengji is the leading manufacture of alloy steel pipe. It is widely used as barrel & plunger, motor housing, gas springs, shock absorbers, cylinders, body-building instruments, automotive industry, etc. The alloy steel pipe is recommended for applications where accuracy, roughness and cleanness of the pipe is a priority. The inner and outer walls of the  alloy steel pipe have high accuracy and excellent roughness (Ra=0.2 - 0.6).The materials can be altered to meet customers' requirements. Shengji  alloy steel pipe can also withstand high pressure. Both the inner and outer walls have a smooth finish with no oxidation layer on the surface. Our pipe features the best technology in both domestic and international markets.
