Stainless steel welded pipe needs to be protected by nitrogen when welding. What is the principle of nitrogen-protected stainless steel welded pipe ?
When the stainless steel welded pipe is welded, the weld bead in the stainless steel welded pipe is cooled in an oxygen-free environment to ensure that the inner bead is not oxidized by high temperature. The protected bead presents a white-like line instead of an oxidized red or black line. Such a weld bead is smooth and tidy, does not burst easily when bent, and is more malleable.
The cost will be considered in production, and the cost of other pipes without internal protection will definitely increase. However, we insist on the quality as the core and insist on the use of nitrogen protection when producing stainless steel pipes. Although the addition of nitrogen gas protection increases the cost, it is a good quality guarantee for manufacturers who process stainless steel welded pipes!
