Seamless Steel Pipe Manufacturing Process
Main production processes of hot-rolled seamless steel pipes (main inspection processes):
Tube billet preparation and inspection → tube billet heating → perforation → tube rolling → steel pipe reheating → fixed (reduced)
diameter → heat treatment → finished tube straightening → finishing → inspection (non-destructive, physical and chemical, bench
inspection) →in storage.
Seamless Steel Pipe Quality Inspection
â‘ Inspection of steel pipe wall thickness
â‘¡Examination of outer diameter and ovality of steel pipe
â‘¢Check the length of steel pipe
â‘£ Inspection of steel pipe bending
⑤ Inspection of bevel angle and blunt edge of steel pipe end face
â‘¥Ultrasonic flaw detection UT
