Why does 20# seamless steel tube have a fracture problem? The main possibilities are as follows:

1. Tube blank, the quality of tube blank directly affects the quality of the 20# seamless steel tube after rolling.

2. The temperature control of rolling tubes. In some small workshop-type factories, the processing temperature does not meet the standard requirements at all. The uneven heating and insufficient temperature of the steel tube will affect the quality of the 20# seamless steel tube.

3. Processing equipment. Old processing equipment or equipment with problems, will affect the quality of the 20# seamless steel tube, and such problems as pits, warped skin, inner layer fracture, etc. will generate.

This kind of 20# seamless steel tube quality is not up to standard, is a common thing in small workshops. Large manufacturers will strictly implement the standards and specifications to ensure the quality. At the same time, the price is appropriately higher.  You get what you pay for.
