The cleanliness and smoothness of seamless steel tube are the necessary conditions for choosing seamless steel tube. Now everyone will see it when they buy it, which is the key to whether customers can buy it successfully. So what is the cause of this situation? The following seamless steel pipe manufacturers will tell you in detail.


First, raw material factors. The quality of tube blank is poor, and there will be scabs, cracks and so on inside and outside the skin.


The second is the temperature coefficient. The first important process of seamless steel tube production is heating, and poor heating (uneven, insufficient temperature, etc.) will cause internal skin, etc.


Third, equipment factors. Beginning with the furnace, each component of the equipment will affect the final quality of the pipeline. For example, if the equipment parts are scratched, it will lead to skin and pits; if the punch is not smooth, the head of the billet will be bitten by water, it is difficult to bite or the head will warp inside;


Fourth, process issues. Technological problems are also very complex. There are adjustment problems, equipment failure problems and pipeline quality caused by wear and tear of process components (head, guide rail, rollers, etc.). The problems are all-encompassing.
