MLC Composite Pipe and Fittings

Product Description

MLC (Multilayer Composite) Pipe and Fittings are advanced plumbing components used in modern water supply and heating systems. These pipes are manufactured using multiple layers of materialstypically PEX (cross-linked polyethylene) and aluminumwhich are bonded together to form a strong, flexible, and durable pipe structure.

Structure

An MLC pipe usually consists of five layers:

1. Inner Layer (PEX) Safe for drinking water and resistant to corrosion and scaling.

2. Adhesive Layer Bonds the plastic layer to the aluminum layer.

3. Aluminum Layer Provides strength, shape stability, and prevents oxygen penetration.

4. Adhesive Layer Ensures strong bonding between layers.

5. Outer Layer (PEX or PE) Protects the pipe from external damage and environmental effects.

Key Features

• Corrosion Resistant Does not rust or corrode like metal pipes.

• High Temperature Resistance Suitable for both hot and cold water supply.

• Leak-proof Joints Compatible with press fittings, compression fittings, and push fittings.

• Flexible but Strong Easy to bend and install while maintaining strength.

• Low Thermal Expansion Aluminum layer reduces expansion compared to plastic pipes.

• Long Service Life Typically lasts 50 years or more under normal conditions.

Applications

• Residential and commercial hot and cold water supply systems

• Underfloor heating systems

• Radiator heating systems

• Compressed air systems

• Industrial fluid transportation

MLC Pipe Fittings

MLC pipes use special fittings such as:

• Elbow fittings

• Tee fittings

• Couplers

• Reducers

• Male and Female adapters

These fittings are usually made from brass or PPSU material and ensure secure, leak-free connections.

Advantages Over Traditional Pipes

• Lightweight and easy to install

• Better durability than PVC pipes

• Less expansion than PPR pipes

• Smooth inner surface for better water flow
