PE-AL-PE Aluminum-Plastic Composite Pipe Multilayer Pipe for Gas & Water

Description

Ruisongbuild PE-AL-PE Composite Pipe: The Ultimate Multilayer Piping Solution

The Ruisongbuild PE-AL-PE pipe (Polyethylene-Aluminum-Polyethylene) is a high-performance composite tubing that brings together the best of both worlds: the corrosion resistance of high-density polyethylene and the structural strength of aluminum. This advanced 5-layer construction ensures high mechanical strength and thermal stability, making it one of the most reliable piping materials for modern gas and water infrastructure.

Advanced 5-Layer Structure

1. Inner Layer: Food-grade PE, smooth and hygienic for fluid transport.

2. Adhesive Layer: High-strength hot-melt glue bonding the PE to the metal.

3. Aluminum Core: Overlap or Butt-welded layer providing 100% oxygen barrier and rigidity.

4. Adhesive Layer: Secondary bonding layer for structural integrity.

5. Outer Layer: Durable PE protecting the pipe from external impacts and UV.

Top Benefits of PE-AL-PE Multilayer Pipes

• 100% Oxygen & Light Barrier: The aluminum layer prevents oxygen and light from penetrating the pipe, eliminating the growth of algae and protecting system components (like boilers) from oxidation.

• Shape Retention (Bendable & Stable): Unlike pure PE pipes that spring back, PE-AL-PE can be bent by hand and stays in its shape, reducing the number of fittings needed.

• Lower Thermal Expansion: The aluminum core significantly reduces the expansion and contraction common in plastic pipes during temperature changes.

• Superior Safety for Gas: The metal layer provides a high safety factor for indoor gas distribution (Natural Gas, LPG).

Choosing the Right Composite Pipe

• For Indoor Gas & Cold Water: This PE-AL-PE pipe is your most cost-effective and reliable choice.

• For High-Temp Underfloor Heating: We recommend upgrading to our [PEX-AL-PEX Pipe] which handles temperatures up to 95°C.

Frequently Asked Questions

Q1: Can PE-AL-PE pipes be used for gas transport?
A: Yes. PE-AL-PE composite pipes are widely used for indoor low-pressure gas distribution (Natural Gas and Liquid Petroleum Gas). The aluminum layer provides a reliable gas-tight barrier, and the yellow-colored jacket is typically used to identify gas lines.

Q2: What is the difference between PE-AL-PE and PEX-AL-PEX?
A: The main difference is the material’s temperature resistance. PE-AL-PE uses standard polyethylene and is generally used for cold water and gas (up to 65°C). PEX-AL-PEX uses cross-linked polyethylene, which allows it to handle much higher temperatures (up to 95°C), making it the standard for radiator and underfloor heating systems.

Q3: Does the aluminum layer rust?
A: いいえ. The aluminum layer is completely encased between two layers of polyethylene and high-strength adhesive. It never comes into contact with the water or the external atmosphere, ensuring it remains protected from corrosion for the life of the pipe.

Q4: How do I connect PE-AL-PE composite pipes?
A: These pipes are typically joined using compression fittings or press fittings. Because the pipe can be bent and holds its shape, you can often run long continuous lengths, significantly reducing the number of joints required compared to rigid PVC or metal pipes.

Q5: Is PE-AL-PE pipe safe for drinking water?
A: Yes. Ruisongbuild PE-AL-PE pipes use food-grade inner layers that are non-toxic, odorless, and lead-free, complying with international standards for potable water supply.
