PPR-AL-PPR reinforced-plastic pipes

Specifications

The reinforced-plastic pipes are a next advance step in PPR pipe building industry evolution.
They do not apparently differ from the commonly used reinforced pipes featuring both the same polypropylene outer layer and aluminum foil. But the foil is disposed in another way more closer to the inner and not to the outer part of the pipe.

The outer diameter size of the new pipes is the same as the size of the conventional, not reinforced pipes, so they do not need shaving before welding operation, thus providing considerable time and labour savings, especially when the large pipe diameters  are concerned.
The second special feature of the new  reinforced-plastic pipes is that their inner layer coming in contact with gas and fluids, can be made of various plastics  such as PPR, PEX, FB, HDPE, LDPE depending on the given technical application. The pipe applications can be therefore greatly extended beginning from conventional heating systems up to narrowly-specialized areas, related, for instance, to the chemical industry.
During pipe fabrication the aluminum foil is subject to ultrasonic welding and bonded to the PPR layers by means of  special-purpose adhesive.

The reinforced-plastic pipes are certified in accordance with European Standard EN ISO 15874:2003 and German Standard DIN 8077-8078.
