Description
Rigid Polyurethane Spraying Polyethylene Winding Prefabricated Directly Buried Insulating Pipes Production Line
Spraying winding pipe production line, the spraying and winding process set by Walstar first carried out shot blasting and rust removal treatment on the surface of the steel pipe. After polyurethane spraying was completed, polyethylene sheet could be wrapped. After cooling and cooling, the polyethylene outer layer would produce circumferent shrinkage force, increasing the reliability of the trinity.

Advantage economy of materials


Rigid Polyurethane Spraying Polyethylene Winding Prefabricated Directly Buried Insulating Pipes Production Line
Polyethylene winding, the semi-finished pipe sprayed with polyurethane insulation layer is spirally run on the transmission line, the extruder extrudes a certain thickness of molten polyethylene sheet is wound on the outer surface of the insulation layer, with the continuous rotation of the semi-finished pipe, the extruder continuously extrudes the molten polyethylene sheet, and is superficially wound on the surface of the polyurethane layer according to the controlled pitch.

Technological flow of the polyurethane coating steel preinsulated pipe equipment:
1. Remove rust from steel pipe surface
2. Heat 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

Rigid Polyurethane Spraying Polyethylene Winding Prefabricated Directly Buried Insulating Pipes Production Line
Composition of the polyurethane coating steel preinsulated pipe equipment:

1. Shot blasting rust removel machine

2. Medium-frequency induction heating furnace

3. Polyurethane spraying unit

4. Single screw extruder and diehead mould

5. Finished pipe ends trimming machine

6. Conveyers, racks and robotics to move and handle the pipe

7. Electrical system and PLC

Rust removal of steel pipe/piece, the hydraulic lifting mechanism is used to transport the steel pipe/piece to the transmission pipe conveying line of the steel pipe shot blasting cleaning line, and the steel pipe/piece is turned and entered the shot blasting room. When the signal of the steel pipe/piece is collected by the internal sensor, the control system commands the shot gate to open, and the pellets are thrown against the outer wall of the steel pipe to remove the rust and impurities attached to the outer wall of the steel pipe. The steel pipe workpiece enters the output roller table, and after shot blasting, the outer surface of the steel pipe workpiece meets the requirements of sa2.5.

Polyurethane spraying, the steel pipe in a certain Angle of the rotating tugboat uniform speed, spraying robot will be the polyurethane raw materials in the shape of umbrella, fog and mixed evenly spray on the spiral forward steel pipe, polyurethane raw materials launched within a certain period of time, to meet the technical requirements of the compressive strength and design thickness, to complete the production of spraying insulation layer. Multiple spraying can be performed when the required thickness is large.
