Brief Description

RISONG multilayer pipe is a 5-layers composite pipe that combines the advantages of metal and plastic pipe and eliminates the disadvantages of both materials at the same time. The inner layers and outer layers of mutilayer pipes are made from HDPE, Pex-b or PERTmaterials, which are tightly boned with middle aluminum core layer by using a special glue.The aluminum core is absolutely diffusion tight, it reliably prevents oxygen/gases from permeating into pipe.It compensates and reduces snap-back forces and heat expansion with changes of temperature.

Advantages 

■   Resistance to high temperature and high pressure, resistance to erosion and the noiseless  water hammer.

■   Clean and hygienic and oxygen-proof, flexural resilience.

■   Smooth in wall guaranteeing the least resisting force and the largest amount of water.

■   Easily transferred and stored, a longevity of over 50 years.
