Introduction of Product

Polyurethane spraying polyethylene wrapping pre-insulated pipe production line is used for the production of polyurethane prefabricated direct buried thermal insulating pipes, which are widely used in the field of heating, cooling and crude oil transportation.

Our company has independently developed a Polyurethane Spray-coated Polyethylene Heat-wrapped Insulation Pipe Production Line. This equipment is patented in multiple areas and has received a Level 5 rating in technical advancement according to third-party standardized evaluation reports, reaching a leading position in the domestic market. It has also been awarded as the first set of technological equipment in Shandong Province.

The production line utilizes a continuous or intermittent spray coating process, offering high automation, fast production efficiency, and material savings. The system increases the closed-cell rate of the foam, reduces water absorption, and achieves a triple-combined molding structure, ensuring more reliable performance. The products are low-carbon, environmentally friendly, and offer higher economic and social benefits.

This cutting-edge technology not only provides superior product quality but also contributes to a more sustainable and efficient future.
