Seamless steel pipes are also widely used in fields such as mechanical manufacturing, construction engineering, and aerospace industry. In mechanical manufacturing, seamless steel pipes can be used to manufacture various mechanical parts and components, such as cylinders for air compressors, bearings for supporting spindles, etc
Seamless steel pipe production process
①The main production processes of hot-rolled seamless steel pipes (main inspection processes):
Preparation and inspection of tube blank → heating of tube blank → perforation → pipe rolling → steel pipe reheating → diameter determination (reduction) → heat treatment → finished pipe straightening → finishing → inspection (non-destructive, physical and chemical, Taiwan inspection) → warehousing
②The main production processes of cold-rolled (drawn) seamless steel pipes:
Blank preparation→pickling and lubrication→cold rolling (drawing)→heat treatment→straight…
