Seamless pipe supplier tells you that the production process of general seamless steel pipes can be divided into two types: cold-drawn and hot-rolled. The production process of cold-rolled seamless steel pipes is generally more complicated than that of hot-rolled. After extrusion, a sizing test should be carried out. The Seamless pipe supplier tells you that if the surface does not respond to cracks, the round pipe should be cut by a cutting machine and cut into a blank of about one meter in length.

The Seamless pipe supplier tells you to enter the annealing process. The annealing should be pickled with acidic liquid. When pickling, pay attention to whether there is a lot of blistering on the surface. If there is a lot of blistering, it means that the quality of the steel pipe does not meet the corresponding standards. . Seamless pipe supplier tells you that cold-rolled seamless steel pipes are shorter than hot-rolled seamless steel pipes in appearance. The wall thickness of cold-rolled seamless steel pipes is generally smaller than that of hot-rolled seamless steel pipes, but the surface looks more than thick-walled seamless steel pipes. Bright, the surface is not too rough, and the caliber does not have too many burrs.
The above is the seamless steel pipe production process explained by Seamless pipe supplier. I believe you have some understanding. If you have any questions, please call us.
