The structure of the new AQUART pipes incorporates three layers: the inner and the outer polypropylene (PPR) layers filled with special additives and PPR-to-PPR middle fiberglass layer.
The outer layer is made of PPR-copolymer which can be easily treated during conventional pipe welding. It contains special agent additives making the pipe ultraviolet-resistant.
The second, middle layer of the new AQUART pipes is formed by composite compounds consisting of PPR-copolymer and FB-fiberglass. Such composition provides for improving all technical features of the new AQUART pipes including mechanical strength and resistance against exposure to high and low environmental temperatures.
The employment of new AQUART pipes allowed, among other things, to solve the problem of polymer linear expansion/elongation which is found to be 4,5 times lower in comparison with conventional polypropylene pipes. The FB-fiberglass layer serves as an oxigen barrier allowing to employ the new AQUART pipes in individual heating systems instead of using metal-reinforced pipes.
The third, inner pipe layer is made of PPR-copolymer ensuring the operation of such pipes in water supply systems in full compliance with requirements of sanitary standards.
