Test Requirement
In addition to ensuring chemical composition and mechanical properties, hydrostatic tests are performed one by one, and flaring and flattening tests are performed. . In addition, there are certain requirements for the microstructure, grain size, and decarburization layer of the finished steel pipe.
Advantage
