seamless pipe processing line
Seamless pipe processing line as below:
Production process of seamless steel pipe:
① Main production process (main inspection process) of hot rolled seamless steel pipe:
Tube blank preparation and inspection → tube blank heating → perforation → tube rolling → reheating of raw tube → sizing (reducing) → heat treatment → straightening of finished tube → finishing → inspection (nondestructive, physical and chemical, bench test) → warehousing
② Main production processes of cold rolled (drawn) seamless steel pipe
Blank preparation → pickling and lubrication → cold rolling (drawing) → heat treatment → straightening → finishing → inspection
During the processing of seamless pipe,rolls as piercing rolls,sizing rolls ,reducing rolls and the other type is largely needed.
