Description
China Polyurethane Spraying Foam Preinsulated Steel Pipe Assembly 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


Polyurethane Spraying Foam Pre Insulated Steel Tube Making Machine High Pressure Airless Spraying
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

The polyethylene outer protective layer can reduce the manufacturing cost by 50%, while the ability to resist ring cracking is enhanced, which can meet the use in high cold areas.

The thickness of the insulation layer can be adjusted arbitrarily to meet the different needs of the project and save the project cost.

The polyurethane insulation layer has uniform density and no defects such as cavities.

The surface of the thermal insulation layer formed by spraying is rough, the adhesion with the polyethylene outer sheath is strengthened, and the trinity function of the pipe is strengthened.

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.

In China's thermal insulation pipe production equipment, mainly in the pipe in the pipe, intermittent spray winding process, there are poor production continuity (complex equipment structure, need to be processed in zones, between zones through transfer equipment transfer pipeline), processing pipe diameter and insulation layer thickness limited, lack of accurate working condition monitoring, raw material consumption and energy consumption, some auxiliary operations still rely on manual and other problems. The application of insulation pipe production equipment is restricted.
