using hot rolled steel pipe billet to make heating and piercing, elongating, sizing and stranghtening, cooling, finally hollow bars finished, this is the type most commonly used. Because it is hot rolled, so cost is lowest, but it is suit for large quantity, for small quantity, have to make cold drawn or round bar piercing. size:outer diameter 32mm- 499mm, wall thickness 4mm- 80mm.
How to distinguish hot rolling and cold rolling seamless tube?Hot rolled seamless steel pipe is generally divided into low, medium, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, geological steel pipe and other steel pipe. The outside diameter of hot rolled seamless tube is generally greater than 32mm and the wall thickness of that is 2.5-75mm. Difference
Production process and production technology of hot rolled Sep 18, 2020 · PQF unit can produce high strength (above P110) special grade oil well pipe, high pressure boiler pipe and 13Cr, 304L stainless steel pipe. The biggest advantage of PQF is that because the radius difference of three roll pass is less than that of two roll pass, the deformation of rolled piece is more uniform and stable, and the wall thickness accuracy and surface quality of products are higher
