The China PVC Pipe Mold company introduces much international and advanced equipment at home and abroad.
Seamless steel pipe is a long strip of steel with a hollow section and no welds around it. Mainly used to transport fluids, such as oil, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, seamless steel pipe is lighter with the same bending and torsional strength. It is an economical cross-section steel. It is widely used in the manufacture of Home Appliance Mould Factory structural parts and mechanical parts. Stainless seamless steel pipes are used to manufacture ring parts, which can improve the material Utilization rate, simplifying the manufacturing process, saving material costs and processing hours, such as rolling bearing rings, jack sleeves, etc., are currently widely used in steel pipe manufacturing.
Seamless steel pipe can be divided into round pipes and special-shaped tubes according to the different cross-sectional area shapes. Since the circular area is the largest under the condition of equal perimeter, more fluid can be transported by the circular tube. In addition, the ring cross section is more uniform when subjected to internal or external radial pressure. Therefore, most seamless steel pipes are round pipes. However, round pipes also have certain limitations. For example, under the condition of being bent in a plane, round pipes are not as strong as square or rectangular pipes. Some agricultural machinery skeletons, steel-wood furniture, etc. are often used in square and rectangular pipes.
Seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe, extruded pipe and so on according to different production methods. 3.2 According to the shape classification, there are round tubes and special-shaped tubes. In addition to square tubes and rectangular tubes, there are oval tubes, semi-circular tubes, triangular tubes, hexagonal tubes, convex tubes, plum-shaped tubes, etc. 3.3 According to different materials, it is divided into ordinary carbon structure pipe, low alloy structure pipe, high quality carbon structure pipe, alloy structure pipe, stainless pipe and so on. 3.4. According to special purpose, there are boiler tubes, geological tubes, petroleum tubes, etc. Changsha Xiangjia Metal Materical Co., Ltd. the Steel Pipe Division of ADTO GROUP, is one of the leading manufacturers of steel pipe in China. We supply ERW steel pipe in high quality. We supplier high qulity seamless steel pipe in various calibers.
