Forged pipe fittings are a product with good mechanical properties in flange products. Its raw material is generally a pipe blank, which is then cut and then continuously beaten to eliminate defects such as segregation and looseness in the steel ingot.

In the welding operation of stainless welded steel pipe manufacturers, the market faces three common problems: unqualified seams, incomplete penetration or burned through, cracks and pores.

High-frequency welding is a kind of induction welding (or pressure contact welding). It does not require weld fillers, no welding spatter, narrow welding heat-affected zone, beautiful welding shape, good welding mechanical performance and other advantages.

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.
