Seamless steel tube surface crack coefficient
The cleanliness and smoothness of the seamless steel tube is a requirement for the choice of seamless steel tube. Now everyone will look at it when they buy it, which is the key to whether customers can buy it successfully. So what are the factors that lead to this? The seamless steel tube manufacturers below will tell you in detail.
First, the raw material factors. The poor quality of the tube blank will appear inside and outside the skin, crusting, cracks, etc.;
Second, the temperature factor. The first important process of seamless steel tube production is heating, poor heating (uneven, insufficient temperature, etc.) will cause internal skin, etc.;
Third, equipment factors. From the beginning of the furnace, each equipment component will affect the final quality of the pipe. For example, if the equipment parts are scratched, it will cause the outer skin and pits; if the punching machine is not smooth, the head of the tube blank will be bitten by water and it will be difficult to bite or the inside of the head will be warped;
Fourth, the process problems. Process problems are also quite complex, there are adjustment problems, problems with equipment failure, and the quality of the pipe produced after the wear of process parts (heads, guides, rolls, etc.). The problems caused are all-encompassing.
