Production Process and Feature
High-pressure pipes' production process: heating of perforation of billets, billets and billets, and expansion of steel pipes.
The rolling of high-pressure pipes, the sizing and decrease in steel pipes, the heating and finishing of steel pipes, or the heating and perforation of steel blanks, hot rolling, pickling, cold-drawn carbon burning, along with the final product, a seamless steel pipe manufacturing method, Is characterized by the installation of a mandrel-type seamless tube rolling mill where a rolling rack with a plurality of rolls and a plurality of successively arranged rolling instructions different from each other are set up, and the seamless steel tubing is rolled on this type of production line Then, measure the wall thickness at the circumferential direction of the wrapped steel pipe at multiple points, and according to the measurement outcome, at least to control the positions of both ends of each axis of the rolls onto the last rolling stand of the mandrel-type smooth pipe rolling mill. To be able to lessen the wall thickness.
Application
High-pressure pipe is a sort of pipe that can withstand pressure. This tube is used to transport liquid. There are various kinds of it, such as steel pipe, copper pipe, stainless steel pipe, and many others. It's mainly utilized to fabricate high quality carbon structural steel and metal structural steel high-pressure pipes for steam boiler pipes with high pressure and over. Stainless steel high-pressure pipes are used more and more broadly
