Aluminum Alloy Plastic Composite Pipe System

Applications of aluminum alloy plastic composite pipe system
This pipe is utilized most often for high rise pipe system installation, and will not deform when exposed to excessive heat or compression. It can be installed either vertically or horizontally, and is UV and oxygen corrosion resistant, as well as resistant to corrosion on related metal parts and radiators, thus improving the overall service life of the pipe system.

Note: according to the national construction industry standard CJ/T321-2010 technical specification, the pressure and temperature resistance grade and service condition of aluminum alloy plastic composite pipes depends on the inner pipe and outer pipe wall thickness, which are not related to the inner pipe material, rules are as follows:

1) the inner and outer pipe wall thickness of aluminum alloy plastic composite pipe shall not be less than the data listed in this table, the allowable deviation is greater than or equal to 0.

2) the pressure resistance grade of aluminum alloy plastic composite pipe system shall not be less than PN2.5MPa.

Features of aluminum alloy plastic composite pipe system
1. Rigid and flexible: The aluminum alloy plastic composite pipe system has a number of advantages, including excellent hygienic performance, corrosion resistance, small thermal conductivity, great transportation performance, external composite hardness aluminum alloy protective surface, high rigidity, impact resistance, resistance to ultraviolet radiation, a high performance grade and smooth appearance.

2. Attractive in price and quality: Because the pipe material, including the main pipe components, are made of a polymer material, they overcome the shortcomings of expensive stainless steel or copper pipes, while still offering a lightweight, rigid performance with long term applications.

3. Applicable for a variety of projects: Compared to traditional pipes, these pipes save installation labor costs and equipment costs, as well as reduce operation and maintenance costs, all while extending the service life.

Product introduction
Palconn aluminum alloy (PB, PP-R, PE-RT) composite pipes are a new pipe variety developed independently here at Palconn industry. It utilizes unique technology for use of an aluminum alloy pipe and plastic pipe in order to form a two layered structured pipe using pre-stressed compositing.
