Through statistical analysis and probability analysis. 25% of the 70,000 tons of stainless steel welded pipes is used reliably in the petrochemical fertilizer boiler and nuclear power industry of aerospace spacecraft. There are still about 20% of nonconforming or usable products. The main problem is that the chemical composition of steel pipe exceeds the allowable deviation. The purity of steel is not enough, impurities exceed standard, resulting in unqualified particle size; Disqualification of intercrystallite corrosion; Internal and external surface defects are serious, internal wrinkles are not removed, and they are heavily biased to the wall.

Today, pipe welding plays an essential role in virtually every industry. Welded pipes often have tighter dimensional tolerances than seamless steel pipes. As a result, they better suit to environments where corrosion resistance is a greater factor than pressure containment. Welded tubes and pipes are generally more cost effective than the equivalent.
