Precision Rectangular Pipe - Nanning Rectangular Pipe - Nanchang, Jiangxi automobile frames dedicated Rectangular Pipe - Chengdu, Sichuan Rectangular Pipe - Xi'an, square and rectangular steel pipe manufacturing annular parts, can improve material utilization, simplify the manufacturing process, saving material and machining hours of work, such as bearing rings, jack sets, has been widely used to make steel. By cross-sectional shape of the pipe can be divided into tube and shaped tubes. Since the perimeter of equal conditions, the maximum area of ??a circle with a circular tube can carry more fluid. In addition, the circular cross section to withstand internal or external radial pressure, the force is uniform, so the vast majority of the pipe is pipe. However, the tube also has some limitations, such as by plane bending conditions, the tube is not as good as square, rectangular tube bending strength, some of the farm skeleton, steel and wood furniture to common square and rectangular pipes.
