Advantages of multilayer composite pipe
Corrosion resistance
Multilayer composite pipes are completely impervious to consumption, guaranteeing a more extended life expectancy contrasted with conventional metal lines. They are appropriate for both hot and cold water applications.
01
Adaptability
The adaptability of multilayer composite pipe makes them simple to introduce in restricted spaces and around problems. Their adaptability additionally lessens the gamble of line blasts brought about by cold temperatures.
02
Thermal insulation
The aluminum layer in multilayer composite pipe gives brilliant warm protection properties, limiting intensity misfortune and further developing energy productivity.
03
Smooth inside surface
Multilayer composite pipes have a smooth inside surface, avoiding the development of scale and parts that can influence water stream and quality.
04
Oxygen barrier
The aluminum layer in the multilayer composite pipe acts as an effective oxygen barrier, preventing oxygen from entering the water, which is critical in hydronic heating systems.
05
Residential plumbing
Due to their flexibility and resistance to corrosion, multilayer composite pipes are increasingly being used in residential plumbing systems for both hot and cold water distribution.
Industrial piping systems
In industrial settings, where durability and resistance to chemicals are critical, multilayer composite pipes offer a reliable solution. They are commonly used in chemical plants, water treatment facilities, and food processing industries.
Heating and cooling systems
With their high thermal resistance, multilayer composite pipes are an excellent choice for heating and cooling systems in both residential and commercial buildings.
Gas distribution
Multilayer composite pipes are also used in gas distribution systems, offering a safe and durable solution that can handle high-pressure environments.

Parts of a Multilayer Composite Pipe
A multilayer composite pipe consists of three main layers:
Inner Layer
The inner layer is made of cross-linked polyethylene (PE-X), which provides excellent resistance to chemicals and high temperatures. This layer ensures that the pipe remains hygienic and prevents the growth of bacteria.
Intermediate Layer
The intermediate layer is typically made of aluminum, providing stability and strength to the pipe. The aluminum layer also acts as an oxygen barrier, preventing the diffusion of oxygen into the pipe and protecting against corrosion.
Outer Layer
The outer layer is made of cross-linked polyethylene (PE-X) or polyethylene (PE), which provides protection against UV rays and mechanical stress. This layer also ensures the pipe's flexibility and ease of installation.
The manufacturing process of multilayer composite pipes involves several steps:
Extrusion of inner and outer layers: The inner and outer layers are extruded separately using a high-quality cross-linked polyethylene or polyethylene material. The extrusion process ensures that the layers have uniform thickness and consistent quality.
Adhesive bonding: After extrusion, the inner and outer layers are bonded together using a special adhesive. This bonding process ensures the layers remain firmly attached, providing structural integrity to the pipe.
Insertion of aluminum layer: The aluminum layer is inserted between the inner and outer layers. This layer is typically made of thin aluminum sheets, which are corrugated to enhance flexibility. The corrugations also increase the contact surface between the aluminum and polymer layers, ensuring efficient heat transfer.
Welding and calibration: The multilayer pipe is then welded longitudinally to form a continuous pipe. This welding process ensures a strong and leak-free connection. After welding, the pipe undergoes calibration to achieve the desired dimensions and shape.
Quality control: Before the multilayer composite pipes are ready for the market, they undergo rigorous quality control checks. These checks include testing for pressure resistance, dimensional accuracy, and overall performance.
