Cold pull tubes are used for cold or cold -rolled precision seamless steel pipes for mechanical structure and hydraulic equipment.Cold pipes, cold -rolled steel pipe crews are the entire set of equipment combinations of cold processing methods combined with cold, cold or cold rolling and cold pull -up methods. It is a unit of deep processing of hot -rolled tube or welding.
Cold pulp pipe standard
The raw material of the cold pull tube is the hot -rolled steel pipe. After pickling the oxidative skin of the hot -rolled steel pipe, the cold chain is tied. The finished product is a hard roll, because during the production processThen it caused cold hardening, so that the intensity and hardness of rolling rolled rolled rolled rolled rolled rolled rolled rolled rolled rolled scrolls, and the tough plastic indicators decreased. Therefore, the stamping performance is constantly deteriorating, because it can only be used for simple deformation parts, rolling hard rolls, rolling hard rollsIt can also be used as a raw material for the hot -dip galvanized factory. Because the facilities of the thermal galvanized unit are degraded, in general, the process of cold pull -out pipes is to be tuned and then heated.Then the annealing, after completing the acid washing, then the oil, the copper plating, and the multiple cold pull -off, which is the cold rolling, and the bad tube and thermal treatment.It also needs to be tested by hydraulic pressure, commonly known as detective, and finally entered the warehouse.
Cold pull tube hardness
The ability of metal materials to resist hard objects is called hardness.Depending on the test method and the scope of applications, the hardness can be divided into British hardness, Lowl Hardness, Victoria Hardness, Shaws hardness, microscopic hardness, and high temperature hardness.For pipes, there are three commonly used pipes: Budi, Lowl, and Victoria.The hardness of cold pull tubes is generally around HB330-380.
