Zhongcai Aluminum-plastic Composite Pipeline
The PP-R aluminum plastic steady state composite pipe is a five-layer composite pipe. It is created by organically bonding a PP-R pipe and an aluminum layer with a specially made hot-melt adhesive at high temperatures. This forms a unique composite structure of polypropylene-hot melt adhesive-aluminum layer-hot melt adhesive-polypropylene. The inner and outer PP-R material guarantees the hygienic performance of the material in water supply applications. The inner layer of PP-R, which is close in size to regular PP-R pipe, is the main pressure-bearing body, while the middle aluminum layer provides reinforcement and protection. The organic combination of these five layers achieves stable physical and mechanical properties.
The Advantage of Aluminum-plastic Composite Pipeline

Energy-saving and thermal insulation, more economical. The thermal conductivity is 0.23-0.24 W/M.K, much smaller than steel pipes (43-52 W/M.K) and copper pipes (383 W/M.K), which makes it a good insulating material for customers;

The connection is firm, non-leaking, and easy to install. The PP-R plastic aluminum pipe still uses the same hot-melt socket connection method as the ordinary PP-R pipe.

It has a small linear expansion coefficient, and it does not deform at all when surface mounted. This is 1/5 of that of pure aluminum plastic pipes, close to metal pipes;

High-temperature operation does not allow oxygen to permeate, it is anti-corrosive. The alloy aluminum completely isolates the external air, ensuring safe, stable, and efficient system operation;
Zhongcai SW Direct Melting Steady Pipe-A Blend of Innovation and Performance
The Zhongcai SW Direct Melting Steady Pipe is a multi-layered composite pipe. It uses lap joint aluminum as the middle layer and the inner layer is constructed from PE-RT II type materials. The inner layer, which comes in direct contact with the fluid being transported, primarily protects the aluminum layer and also has some compressive properties. The outer layer, which is the pressure-bearing component, is made from PP-R.


Aluminum Composite Pipe Application
In the production process, a special hot-melt adhesive is used and integrated into the pipe material through extrusion molding. This approach endows the pipe with the key properties of plastic pipes, including corrosion resistance, ageing resistance, good fluid flow, and non-scaling attributes. Furthermore, it brings the advantages of plastic aluminum steady composite pipes, such as high pressure resistance, light-proofing, oxygen seepage prevention, and a low linear expansion coefficient.
Multilayer Pipe Specifications
● It does not need peeling, and can achieve the homogeneous hot melting joint with the reliable connection.
● Unique three- course pressure- bearing structure, and stronger compressive property
● Unique technology makes 100% bonding of the aluminum plastic juncture, to eradicate the occurrence of tripping out of the aluminum plastic juncture fundamentally.
● The inner layer adopts high quality PE-RT II for manufacturing, and the long-term high pressure resistance performance is superior.
● While welding, it is not easy to shrink the hole, and will not influence the flow of the media, to reduce the energy consumption of the system operation.
