Technical advantages of spray foaming method for producing directly buried pre insulation pipes

1. The PU spraying foam and winding PE film process can reasonably determine the thickness of the insulation layer and the thickness of the external protective layer based on the temperature of the transmission medium, thereby reducing unnecessary material waste.

2. The Polyurethane spray foaming production line has a compact structure and fewer links, reducing production costs.

3. The spraying foam density is uniform, ensuring the good insulation effect of the pre insulated pipe.

4. The spraying production method effectively ensures the concentricity of the working steel pipe and the outer sheath, greatly improving product quality.
