Mechanical steel pipe is a seamless steel pipe for transporting petroleum, natural gas, water, various fluid substances and some solid materials, etc. Featured by light weight, good corrosion resistance and low price, our mechanical steel pipe is widely applied to manufacture structural and mechanical parts, including oil pipe, auto transmission shaft, bicycle racks and constructional scaffolding. Our mechanical steel pipe is also an ideal tool for making annular parts like rolling bearing collar, jack sets, and more. Besides, it plays an indispensable role for making conventional weapons such as gun barrels.
