Hot-rolled seamless steel pipe is a round, square, and rectangular steel with a hollow section and no joints on the periphery. When the bending and torsion strength is the same, the weight is lighter. It is an economical cross-section steel. What defects are prone to appear in the production process of steel pipes? Let’s explain it for everyone. 1)…

Read MoreCold-rolled seamless steel pipes are often of small diameter, and hot-rolled seamless steel pipes are often of large diameter. The accuracy of cold-rolled seamless steel pipe is higher than that of hot-rolled seamless steel pipe, and the price is also higher than that of hot-rolled seamless steel pipe. Cold drawn (rolled) tubes are divided into round tubes and special-shaped…
Read MoreIn order to improve the performance of stainless steel pipe (ss pipe), it is often necessary to adopt certain cold working methods, such as cold drawing, cold rolling, cold rolling, cold bending, cold expansion, cold twisting, etc., which can achieve a certain effect and cause certain damage. Cold working is actually like welding, which will inevitably damage the performance…
Read More(1) Hydrostatic test: The expanded steel pipe is inspected one by one on a hydraulic test machine to ensure that the steel pipe reaches the standard required test pressure. The machine has automatic recording and storage functions; (2) Expansion: Expand the diameter of the submerged arc steel pipe to improve the dimensional accuracy of the steel pipe and improve…
Read More1. The application field of pipe is very wide. Pipes are used in many industries. 2. Different industries have different characteristics of different industries, and thus have different technical requirements. 3. Pipe is a relatively mature product, and various industries have corresponding technical standards. 4. Test the pipe, select the corresponding product standard according to the industry in which…
