Only by controlling the quality of longitudinally welded pipes can production operations be carried out safely, which is also an inevitable element to ensure the personal safety of operators.

There are strict and standardized testing methods for detecting whether the quality of fluid seamless pipes meets the standards.

In the production process of large-diameter steel pipes, since the primary processing is performed in a hot state, the heating operation is a very important process that determines the quality of the product.

The quality requirements of anti-corrosion spiral steel pipes are very important in the production process, because it will be related to the safe use of anti-corrosion spiral steel pipes in the later stage. After the production of anti-corrosion spiral steel pipes is completed, its quality needs to be strictly tested.

Understanding seamless pipes, we first need to understand the mechanical properties of this pipe material. The mechanical properties of seamless pipes are very stable, so they can be widely used.
