Product Description
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 in
the industry.
Feature
√ 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.Product Parameters

Our Advantages
√ Significantly reduce production cost
√ High degree of automation
√ Continuous production avoids restrictions on the length of the pipe
√ Flexible pre-insulated pipe can be directly buried underground, requiring smaller trenches
√ Excellent mechanical properties
√ The pre-insulated pipe is airtight and impermeable,anti-chemicaland
corrosion,and the inner pipe is free from oxidation.
√ The pipe can be rolled and transported in rolls, needs less pipe connectors,reduces construction costs, avoids a lot of trouble in
the construction.
