The equipment can continuously roll seamless steel, Pilger rolled seamless steel, longitudinally welded pipe, spiral welded pipe, etc. It can be directly installed on the production line for online measurement, or installed on the flaw detection line and inspection line to measure the outer diameter of the finished pipe.

When the friction force increases, the positive pressure on the strip increases, and the deformation of the strip increases, which causes the roller to strain the strip and produce surface scratches.

Defects produced in the actual production of high-frequency welded pipes are sometimes not caused by one cause, but are usually the result of a combination of multiple factors.

Seamless steel pipe quality inspection is divided into the following aspects: chemical composition analysis; steel pipe geometric size and shape inspection; seamless pipe steel surface quality inspection; seamless pipe steel management performance inspection; seamless pipe steel pipe process performance inspection; none Metallographic analysis of seam pipe and steel pipe.

If the welded pipe is not straight, check first to see if the problem lies in the sizing, because it is a very important point to affect the straightness of the welded pipe.

The seamless steel pipe cone-roll piercing machine is an ancient piercing process. In the early 1980s, the cone-roll piercing machine with horizontal rolls was revived.
