The difference between precision rolled steel pipe and cold drawn pipe

Finish-rolled steel pipe can also be called cold-rolled precision steel pipe. The production of seamless steel pipe is a process with high dimensional tolerance and precision. The inner and outer walls of the finished steel pipe are good, and the surface oxide layer does not exist. The overall performance is good, because if it is used Processing or deformation treatment can improve production efficiency and reduce costs, so the product quality is excellent. Therefore, it has a wide range of applications in the fields of automobiles, petrochemicals, electric power, shipbuilding, aerospace, pneumatic components and other fields.
Cold drawn pipes are made of metal pipes that are cold drawn, usually using a cold drawing machine, so they are not required to be in a high temperature environment, but the residual stress in the cold drawn pipes is large and not too long, but it can improve the toughness of the steel pipes. Mechanical properties and tensile strength. Cold drawn tubes are suitable for some steel mechanical properties such as precision, smoothness and cleanliness, as required.
