Hot-rolled seamless steel pipes are rolled above the recrystallization temperature. Compared with cold-rolled steel pipes, the diameter of hot-rolled steel pipes is larger, the price is lower, and the accuracy is slightly lower than that of cold-rolled steel pipes. Hot-rolled seamless pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.
