Stainless steel seamless pipes with inner diameter ≥6.0mm and wall thickness ≤13mm are tested using W-B75 Vickers hardness testers for rapid, non-destructive inspection. Pipes with inner diameter >30mm and wall thickness >1.2mm use Rockwell hardness testers (HRB/HRC). Pipes with inner diameter >30mm and wall thickness
