One of the most popular products of industrial rolled metal products is stainless steel pipes. The steel from which the pipe is made resists corrosion well, is characterized by high strength and long service life. In addition, the appearance of stainless steel is aesthetic, which reduces the cost of external finishing, stainless steel pipes are a derivative product of rolled metal. Based on the production method, the following types of stainless steel pipes are distinguished:Hot-Deformed; Cold-Deformed; Heat-Deformed;
Products can be made from flat rolled products that are subjected to technological bending and subsequent welding. In this way, welded pipes are obtained. For seamless pipes, the starting material is a stainless circle, and in this case, when making the pipe, stitching, rolling and calibration are used. Stainless seamless pipe as a whole product has increased strength and high mechanical performance. Stainless steel pipes differ in geometric characteristics depending on the diameter and shape of the pipe section, as well as the type of surface treatment. The shape of the cross-section of the pipe can be round, square and rectangular. According to the type of processing, they are divided into: Matte, Polished, Polished.
