PP-R/AL Stable Composite Pipes

Features

Five-storey structure, layers of protection

PP-R aluminum-plastic stable composite pipe has five-storey structure, the mid-layer is welding aluminum tubes, the inside and outside tube is PP-R Plastic, both the inside and outside tube between with the aluminum is PP-Based hot melt adhesive, the middle layer of aluminum alloy pipe is the core framework for the entire pipeline. This structure combines the rigid metal pipe and health and sealing plastic pipe perfectly.

Aluminum oxide layer resistance, health aseptic

The middle layer of aluminum isolates the external air, infiltrating the external oxygen barrier pipe, inhibiting the bacterial survival in the breeding pipeline. It is used to ensure the health of the water in the pipe and to prevent secondary pollution invisible.

Bears small influence of ’expansion in hot and reduction in cold ’, it has a good Anti-distortion performance.

The expansion properties of PP-R aluminum-plastic stable composite pipe is close to metallic materials, and has no apparent ’expansion in hot and reduction in cold ’when install and apply to use, the outside is more straight and attractive. It has obvious advantagesin high-temperature, hot water, heating the area, outdoor pipes installed applications.

Advantages

Greatly reduced linear expansion coefficient ,only 1/4 of that of PP-R ,which means the composite pipes have stable dimensions.

> 100% oxygen tightness,suitable for heating system. > Improved resistant to impulse under low temperature,resistant to UV-rays.

> Working under higher temperature and higher pressure for cool and hot water system. > Easily detected by detector when embedded,owing to the metal layer. > Good performance of heat preservation and low heat conduction coefficient of 0.45W/m.k. > Smooth and sanitary,being good selection for drinkable water system.

Applications > Distribution for cool and hot water; > Pipes for kinds of high-temperature and low-temperature heating system; > Pipes for heating and colling settings in solar energy system; > Pressure pipe for irrigation system. > Duct for drinkable water system; > Industrial transportation for chemical liquids; > Connecting pipe for air-conditions ;
