The process performance of seamless steel tubes (smls tube) can be inspected through four aspects: hydraulic (water) pressure test, flattening test, bending test, and flaring test, to test the suitability of the steel pipe’s own quality in the subsequent processing and manufacturing process. Commonly used process performance tests include water pressure, flattening, bending, and flaring tests. Let me share…
