Hunan Steel Industrial Zone, No.9 Xiangfu Road, Yuhua District, Changsha, China
The ERW steel pipe includes hot-rolled thick wall welded steel pipe, cold-rolled thick-walled welded steel pipe, cold drawn welded steel pipe, and thick-walled welded steel pipe. The welded steel pipe of jacking structure is used in a wide span, for example, it can be used in chemical, petroleum, textile, medical, food and machinery. What is more, the ERW steel pipe can be useful for industrial corrosion resistance because of its special parts and components made of welded steel hot-rolled and cold drawn welded steel pipe. The welded steel pipe used to convey fluid meets the standard of GB/T14976-1994.
The shaped seamless steel pipe is actually one kind of cross-section shape of the API seamless steel tubes. The pipe can be divided into shaped seamless steel pipe wall thickness, wall thickness ranging shaped seamless steel pipe and variable diameter shaped seamless steel pipe according to the different shapes and sizes of the pipe. The shaped seamless steel pipe is suitable for a variety of structural parts, tools and mechanical parts. Compared to the barrel, the ERW steel pipe has a greater capability of torsional bending, which in turn leads to the structural weight reduce and can save steel.
