Continuous Line For Spraying Polyurethane Foam Preinsulated Steel Pipe Production Line
Product description
Vacuum calibrating method pre-insulated pipe outside casing extrusion line is the most advanced and popular machinery in the world. HSD brand absorbs the advanced technology from German and improve to meet development. Especially compared with internal pressure method, Vacuum calibrating method is much better than it for stiffness, pressure resistance and surface smooth.
We aopt PLC automatic operation , Big length-radius proportion screw stem to improve extrusion capacity, optimized design for extrusion mould, Planet cutter suitable for varioul size pipe, and so on. So You choose HSD machinery then you choose saving cost and steady capability and lifelong service etc.
Rigid polyurethane spraying polyethylene winding prefabricated directly buried insulation pipe consists of steel working pipe, spraying polyurethane rigid foam insulation layer and winding polyethylene outer protective pipe. See the following figure for product structure
Technological flow:
Steel pipe Load-up online---->External shot blasting ----> dust collector---->internal blow out---->lifting transport pipe trolley---->transport to chuck----> chuck hoist cylinder----> alignment chuck center---->mechanical arm station adjust---->chuck hydraulic clamping---->chuck guard at both ends----> carrier pipe servo transport---->IF heating----> PU foam spraying----> pipe load down line----> transport pipe ----> PE film wrapping----> water cooling---->cutting down pipeline---->trim end of pipe---->printing mark&loading down finished pipe---->sealing end of pipe

The integrated welded structure, without adjustment devices, cannot be installed when the ground is uneven. The height of the stand cannot be adjusted, resulting in uneven rolling of steel pipes on the stand, too fast rolling, or difficult rolling, which poses a safety hazard.
