Limitations of SSAW Steel Pipe

Spiral submerged arc welded pipe also has its own shortcomings, the spiral pipe section as a large number of pipeline fluid, such as the transmission of oil, natural gas, gas, water and some solid materials such as pipes. The same low bending strength compared to other steel and solid bars, an economical section steel, is widely used in the manufacture of structural and mechanical parts such as drill pipe, drive shaft, bicycle frame and steel scaffolding.


Steel pipe manufacturing ring parts, can improve material utilization, simplify the manufacturing process, saving materials and processing time, such as bearing rings, jackets, has been widely used in the manufacture of steel. Steel or a variety of indispensable weapons of conventional weapons, barrels, barrels are made of steel. According to different cross-sectional shape of the tube can be divided into tubular and special-shaped tube. Because of the same conditions on the circumference, the maximum area of the tube can accommodate more fluid. In addition, the circular cross-section is subject to internal or external radial pressure, the force is uniform, so the vast majority of pipelines are pipelines.


However, the pipe also has some limitations, such as bending under the conditions of the plane, such as square tube, rectangular tube bending strength, and some agricultural machinery skeleton, steel furniture and the popular square, rectangular tube. According to different uses should also have other shaped tube cross-sectional shape.
