Cold Storage Coal Mines Petroleum Chemical Flexible PERT / PE / PPR Pre-Insulated Pipe Production Line
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.
This kind of pipe is a new generation of PU insulation pipe, with many advantages, such as light, easy operation, few joints, and good flexibility.
It is mainly used to transport heat from main pipe system to housing estate or buildings.
√ Insulation:
The thermal conductivity is as low as 0.013, which is 4 to 9 times better than that of traditional materials. The 92% closed-cell rate ensures a lifespan of over 50 years.
√ Anti-corrosion property:
The foam layer is closely bonded, isolating air moisture and ensuring long-lasting durability in harsh environments.
√ Economy:
Save 50% of excavation costs and 90% of civil construction costs, shorten the construction period by half, and use intelligent control to reduce energy consumption.
√ Environmental friendliness:
Less land occupation, zero waste in production, and green processes are more sustainable.
