Polyurethane Spraying Foam Preinsulated Steel Pipe equipment
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.

The hydraulic sensor automatically controls the upper and lower
tubes and monitors the thickness of the insulation layer online
The running speed of the production line is automatically
controlled according to the process requirements. The production
line is suitable for the production of insulation pipe products
with different insulation thickness and different pipe diameters.
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.
