Thick-walled Carbon Seamless Pipe(ASTM A106)
Thick-walled Carbon Seamless Pipe(ASTM A106) Manufacturing Process:
Hot-rolled (extruded carbon seamless pipe) round tube → heating → perforation → three-roll rolling, rolling or extrusion → detached → sizing (or reducing) the cooling → straightening → hydrostatic test (or testing) flag → storage.
The raw material for rolling Thick-walled Carbon Seamless Pipe(ASTM A106) is seamless tube round.Heating is the furnace.The billet is fed to the furnace heating temperature of about 1200 ° C.The fuel is hydrogen or acetylene.The furnace temperature control is a critical issue.Round tube came out after pressure punch perforation.
Generally,the cone-shaped roller perforation machine is used for punching, This kind perforation machine have high production efficiency,good product quality and large amount of diameter,It can perforate a variety of of kinds of steel,The tube rounds were on the successively been three-roll skew rolling, continuous rolling or extruded.
