What is the difference between hot rolling and cold rolling in stainless steel pipes, and are their uses the same? We usually call hot rolling hot expansion, which is to use a mold to expand and round the pipe. Cold rolling is the opposite, with a fixed mold on the outside and a fixed mandrel on the inner hole, which makes it thinner from the outside. Annealing is required before hot rolling, but not for cold rolling.

There is no difference in use between hot rolling and cold rolling in Sanitary Valve, except for the different processes.

Cold drawing is now widely used in the production of industrial-grade stainless steel pipes in Wenzhou. However, after the emergence of the more efficient 2-roll cold rolling unit, many powerful manufacturers have equipped it. Due to the high price, most manufacturers purchase a small number of them. It is generally produced in conjunction with the cold drawing unit to improve efficiency and reduce production costs.
