According to the production method, steel pipes can be divided into two categories: seamless steel pipes and grooved steel pipes. According to the production method, seamless steel pipes can be divided into hot rolled seamless steel pipes, cold drawn steel pipes, precision steel pipes, thermal expansion pipes, cold spinning pipes and extruded pipes. Seamless steel pipes are made of high-quality carbon steel or alloy steel, which can be divided into hot-rolled and cold-rolled (drawn). So what is the difference between a heat pipe and a cold drawn pipe? let's see .
