Seamless Stainless Steel Pipe manufacturing process and use test
Oct 19, 2018

The Seamless Stainless Steel Pipe is referred to as a seamless tube, and the surface of the finished product is rough. Currently, it is mainly used for boilers, central air conditioners, steel structures, machining, pipeline gas, fire protection, and the like. Due to different application requirements, it is often necessary to adopt different manufacturing processes for processing. Mainly can be divided into hot rolling, extrusion, cold drawing and cold rolling these basic types.


In addition, according to the different cross-sectional shapes of seamless stainless steel pipe products, they can be mainly divided into round pipes and special-shaped pipes. The former is widely used, and there are also some square, rectangular, semi-circular, hexagonal, equilateral triangles, octagons, etc. Seamless tube products. For the time being, the market demand for this product is huge and the application range is more and more extensive.


In practical applications, in order to ensure the application effect, it is necessary to test the performance of seamless stainless steel pipe products, in which the steel pipe subjected to fluid pressure is subjected to hydraulic test to test its pressure resistance and quality, and no leakage occurs under the specified pressure. Wetting or expansion is qualified. Some steel pipes are also subjected to crimping test, flaring test and flattening test according to the standard or the requirements of the purchaser.
