Description

PU Sprayed Foaming HDPE Winding Preinsulation Pipe Continuous 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.

Pipe structure

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:

Technological flow of the polyurethane coating steel preinsulated pipe equipment:

1. Remove rust from steel pipe surface

2. preheat the steel pipe to get it ready for polyurethane spraying

3. Spray polyurethane evenly on steel pipe outer surface

4. Wrap melted HDPE strap around the PU foam

5. Trim the pipe ends


Other supplier racks

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.
