Spiral pipe end-expansion machine
1.Equipment Description: The machine is a special equipment for spiral submerged arc welded pipe production line,which is used to expand the pipe end of the produced spiral submerged arc welded pipe so that the diameter and roundness of the pipe end within a certain length reach the allowable range.Among them,the wall thickness of expandable steel pipe is 5-25.4mm,and the diameter range of expandable steel pipe is:Φ219∼ Φ3000mm 2.Selection range: specification (mm) thicknes s(mm) installed capacity (kw) occupation (m) Φ2540*25.4mm pipe-end expanding machine Φ950*12.7mm pipe-end expanding machine pipe end expansion machine single head layout Φ950*12.7mm pipe-end expanding machine Φ1620*25.4mm pipe end expanding machine
The aircraft by the host,auxiliary equipment,hydraulic,lubrication and electrical systems.
The machine uses a unique expansion of the module technology,so that the base material along the wall stretching and flow,strict control of mold expansion can be the size of the tube end roundness and other precision is improved,this process is called Expanded diameter.
Hydraulic system:The expansion machine is generally double-headed two arrangements,the relative display made,each expansion machine has a separate hydraulic station.The hdraulic station has two main pumps,one for the high-pressure pump,a low-pressure pump,there is an auxiliary pump,the main pump to complete the expansion of hydraulic cylinder fast forward,expanding,packing,unloading and other four workers step;auxiliary pump to complete the module alignment,the carriage forward,back,care rack lift and other steps.
