What are the characteristics of aluminum alloy lined ppr pipe?

The definition of aluminum alloy lined ppr pipe is based on the CJ/T321-2010 standard. The aluminum alloy coated plastic composite pipe is defined as: the outer layer is an aluminum alloy pipe, and the inner layer is a thermoplastic plastic pipe, which is formed by prestressing The double-layer structure composite pipe. The outer layer of the aluminum alloy lined PPR tube is a seamless aluminum tube, which is formed by heating and extruding 6063 deformed aluminum, and then undergoing positive oxidation.

The outer layer of the aluminum alloy coated PPR pipe is 6063 grade modified aluminum, seamlessly extruded (the inner and outer surfaces of the aluminum alloy pipe are oxidized, and the surface coating is greater than 10um). "Plastic" is mainly a plastic tube made of three kinds of food polypropylene PPR polymer resin tube materials. The grade of ppr pipe is S4, which is referred to as "aluminum alloy lined ppr plastic pipe" for short.

PPR plastic pipe with aluminum alloy. The pressure gauge is marked as "dn" and the pipe size is dn20-160. The "lining" of the aluminum alloy composite plastic PPR pipe is the main feature of the production process. The seamless aluminum alloy tube and the plastic tube are organically combined through the prestressing process, and the bonding strength between layers is better.

Features of aluminum alloy lined ppr pipe:
1. Protect health and the environment
The aluminum alloy lined plastic ppr tube can prevent direct light from blocking oxygen, has strong opacity, harmless and balanced colonies, healthy and environmentally friendly food wading raw materials, and smooth medium fluid transmission without dirt, and the friction resistance coefficient on the road is only 0.007.

2. Light steel structure safety
Aluminum alloy lined plastic ppr pipe is a rigid and lightweight pipe, single-plug connection is very practical at home, corrosion resistance, oxygen resistance and aging resistance, S4 lined thermoplastic pipe, to ensure that the rated pressure of the medium transportation in the pipeline system is PN2.5MPa rated pressure After 50 years of normal use, it can operate without maintenance.
