After two years of intensive technological innovation, the Huashida PERT insulated pipe production line has successfully addressed 130 research and development challenges, establishing a comprehensive intellectual property rights solution that is entirely independent. By leveraging precisely engineered extruder screws and barrels, cutting-edge pipe die configurations, and optimally designed cooling systems, this production line ensures the high-quality manufacture of PERT insulated pipes. Its performance and reliability are now recognized as being at the forefront of the internation .

The characteristic of this production line is that the pouring process of polyurethane foam is continuous. The inner pipe is continuously conveyed into the pouring area together with the polyurethane foam mixture, then coated and formed with a film, and then passed through a round die head to be coated with the outer protective layer extruded by the extruder.
