Seamless steel pipe standard
Jun 03, 2016

Seamless steel tube is a kind of hollow, no seams around a strip of steel. Seamless hollow sections, can be used as a transmission fluid pipe, such as oil, natural gas, coal gas, water, some solid material piping and so on. Seamless steel tubes and solid steel round bar compared to resistance to bending and torsional strength is the same as light in weight, is a kind of economic section steel, widely used in the manufacture of structural components and mechanical parts, such as drill, propeller shafts, bike racks and construction steel scaffolding used in the construction. Manufacture of seamless circular parts, can increase material utilization, simplifying the manufacturing process, saving material and processing time, such as Jack and bearing rings, widely used to make. Steel or a variety of indispensable materials of conventional arms, the barrel, the barrel must steel pipe manufacturing. Pipe cross sectional area can be divided into different shapes round tube and tube. Because the perimeter under equal conditions, the largest, with circular tube can deliver more fluid. In addition, the ring cross-section when subjected to internal or external pressure, force more evenly, so most of the steel pipe is the pipe. However, the tube has certain limitations, such as under plane bending conditions, the tube is not square and rectangular tube bending strength, some farm equipment frame, steel-wood furniture, square and rectangular tubes. There need to be other cross-section shapes according to different uses of shaped steel tube.
