pipe expanding machine is designed due to the insufficiency of large diameter seamless steel tube production and specification. It’s a two oil cylinder or four oil cylinder parallel uniform velocity pushing machine, pump station valve table adopts integrated form. Setting the power of medium frequency heating power supply, force and stroke of oil cylinder according to the outer diameter and length of the pipe.
Pipe expanding machine combined by main body,heating coil bracket,hydraulic system,electric system.Main body is welded,bracket welded by shape steel,hydraulic system is integrated system,stable working.
1.Max expanding size 530mm,thickness to 25mm,max raw pipe length available,can make thickness of 508*28mm.
2.Expanding specification: 325mm,426mm,480mm,508mm
3.Material: P11 P12 30CrMo 30CrMo4 35CrMo 12Cr1MoVG 12CrMoG 12CrMo 1Cr5Mo,X52 X70 20Cr20MnVB 12CrNi3
