Special-Shaped Steel Pipe Customization

Special-Shaped Steel Pipe Customization

The special-shaped welded pipe is a precision hydraulic seamless steel pipe made of precision cold-drawn seamless steel pipe by black or gray phosphating process, and the phosphating steel pipe is sealed and rust-proof.

Cold-drawn special-shaped seamless steel pipe can be divided into oval, triangle, hexagonal, diamond, octagonal, unequal hexagonal, five-petal plum shaped seamless steel pipe and so on.

Special-shaped steel tube

Cold-drawn special-shaped seamless steel pipe can be divided into oval, triangle, hexagonal, diamond, octagonal, unequal hexagonal, five-petal plum shaped seamless steel pipe and so on.

The steel pipe used in the hydraulic system is mainly shaped welded pipe and ordinary seamless pipe, shaped welded pipe despite excellent mechanical properties, but due to high price, low precision, has not been widely used. Although the ordinary seamless steel pipe is widely used, its mechanical properties are poor, the accuracy is relatively low, before the use of usually through a series of welding, trial installation, pickling, alkali washing, water washing, long-term string oil, leakage test, complicated processes, time-consuming, unreliable materials, and has not been completely removed the residue in the tube, become a major concern of the entire hydraulic system failure at any time. According to statistics, 70% of the failures in the hydraulic system are caused by this reason.
