PPR Direct Fusion Plastic-Aluminum Stable Pipe-BearCross – Making global trade within your reach

PPR Direct Fusion Plastic-Aluminum Stable Pipe

Product Introduction

New aluminum-plastic composite pipe technology, manufactured with 5-layer composite process. The middle metal aluminum layer enhances pipe physical performance, 100% light and oxygen blocking, eliminating water body microbial growth and secondary water pollution. While retaining original PPR characteristics, the composite technology improves pipe insulation, frost resistance, compression resistance, and impact resistance by more than 2 times compared to standard PP-R pipes. The new direct-melt aluminum-plastic stabilized pipe requires no peeling, one-time direct-melt connection, saving construction time and reducing construction costs. It is the upgraded replacement product for aluminum-plastic stabilized pipes.

Application Scope

1. Production and domestic hot and cold water piping systems

2. Floor heating, wall-hung boiler heating, and radiator heating pipelines

3. Drinking water, reclaimed water, and solar systems

4. Central air conditioning and hot air circulation systems

5. Industrial liquid medium delivery piping systems

Product Features

Three-Layer Pressure BearingUnique three-layer pressure bearing structure with stronger compression performance; strength comparable to metal pipes, easy to bend, eliminating metal pipe brittleness, no rebound after bending.

Excellent PerformanceHigh temperature resistance, high pressure resistance, corrosion resistance; excellent performance suitable for cold and hot water fluid delivery.

Clean and HygienicAlloy aluminum reinforcement layer effectively prevents bacteria and microbial growth.

Low Thermal ConductivityExcellent thermal insulation with thermal conductivity of 0.25w/m·k, far lower than metal pipes; no scaling when conducting heat, no frost when conducting cold, saving external insulation materials. Fluid remains uncontaminated, non-toxic and odorless, ideal for water purification projects.

Easy ConstructionEasy to cut and process; small diameter pipes supplied in coils for arbitrary length; arbitrary bending saves elbows and fittings; convenient installation without peeling; homogeneous heat fusion connection ensures reliable joints.

More Stable PerformanceUnique process ensures 100% bonding at aluminum-plastic interface, fundamentally eliminating plastic-aluminum separation; inner layer made of high-quality PE-RT provides superior long-term high-pressure performance.

Long Service LifeUnder rated service temperature and pressure, PP-R pipe service life exceeds 50 years.
