Heat-resistant polyethylene (PE-RT II) pipes are a new type of polymer chemical building material, featuring excellent heat resistance, corrosion resistance, impact resistance, good flexibility and sealing properties, convenient construction and maintenance, and a service life of over 50 years. They are suitable for secondary piping systems in centralized heating.

Implementation standards:(GB/T 28799.2-2020) "Heat-resistant polyethylene (PE-RT) piping system for hot and cold water Part 2: Pipes"

Product performance characteristics and application advantages

1. 50-year service life
According to the international standard ISO9080, the long-term service life of PE-RT II heating pipes at 80°C can exceed 50 years.

2. Strong pipeline transport capacity
The inner surface of PE-RT II heat-resistant polyethylene heating pipes is smooth, preventing internal wall scaling. The fluid resistance is less than 1/20 that of steel pipes; under the same friction conditions, the thermal load transported by the pipe is at least increased by 25% compared to steel pipes.

3. Good insulation effect with low heat loss
PE-RT II material is a poor conductor of heat, with a thermal conductivity coefficient less than 1/10 that of steel pipes. PE-RT II heat-resistant polyethylene heating pipes reduce heat loss by at least 50% compared to steel pipes, with less than 0.1°C heat loss per kilometer.

4. Lightweight, high welding efficiency, low installation cost, fast progress

5. Reliable and efficient pipe connections
PE-RT II heat-resistant polyethylene heating pipes can be connected using methods such as hot melt connection, electric fusion connection, hot melt socket connection, and flange connection just like PE water supply and gas pipelines.

6. Safe and reliable pipe repair
After damage to PE-RT II heat-resistant polyethylene heating pipes, quick repairs can be made using electric fusion fittings; the repair quality is safe and reliable.

7. Flattened break water repair restoration technology
PE-RT II material is flexible with excellent performance against slow crack growth; it can use flattened break water repair technology for pipeline breaks. After repair under pressure, due to memory effect, the pipeline will naturally restore itself while still meeting long-term usage requirements.

Advantages of second-generation non-crosslinked heat-resistant polyethylene (PE-RT II) pipes

Compared to first-generation PE-RT pipes, all materials in PE-RT II type pipes are high-density heat-resistant polyethylene materials with higher molecular weight that provide better mechanical strength and scratch resistance.
