HDPE Polyurethane Foam Pre-Insulated Pipe Machine

Product Description

HDPE Polyurethane Foam Pre-insulated Pipe Machine 

Product Description

This high-efficiency, energy-saving HDPE outer casing extrusion production line is specifically designed for manufacturing high-density polyethylene protective shells for polyurethane foam insulated pre-fabricated pipes according to international standards.
The line utilizes a vacuum sizing process, resulting in pipes with smooth inner and outer walls, excellent corrosion resistance, superior insulation properties, and outstanding mechanical performance, ensuring a long service life.

The polyurethane sprayed polyethylene thermal winding preinsulation pipe production line independently developed by Huashida, consists of three parts: External shot blasting and derusting collector production line, polyurethane spraying production line, The line has a number of national patents, and the third-party standardized evaluation report has a technology advanced level of 5, reaching the domestic leading level. And won the first set of technical equipment in Shandong Province.
The line adopts continuous spraying production process. High automatic, fast production efficiency, saving raw materials, increased foaming and closed cell rate, lower water absorption rate, trinity molding, and more reliable performance. Products with low carbon environmental protection have higher economic and social benefits.
