Multilayer pipe system

The multilayer system of excellence.
Pexal® is composed of multilayer pipes and different types of fittings that are chosen according to the installation technique adopted.
There are various applications: from the distribution of hot and cold drinking water to centralised water supply systems, from radiator and fan heating systems to radiant floor, wall and ceiling heating and cooling systems, from compressed air systems to industrial plants.

Further details
The advantages of synthetic materials and metal in one product
Reduced pressure loss
The extremely smooth internal surface, as well as preventing the formation of deposits such as lime scale, ensures reduced pressure loss also with the passage of time.

Guaranteed durability of at least 50 years
The system has a guaranteed durability of at least 50 years in compliance with product standards; in this period the product can be used at pressures of 10 bar and temperatures as high as 95°C.

Wide range
The range of fittings, accessories and relative tools is extremely wide and allows all requirements to be met. The fittings are available both in metal and in technopolymer to cover different system applications.

Barrier against oxygen and light
The butt welded aluminium layer acts as a total barrier against oxygen and light, which in plastic pipes would otherwise favour algae growth and the corrosion of the metal parts that make up the system.
Non-toxic materials
The system is made up of materials that are completely non-toxic and is certified for the transport of consumable fluids and drinking water.

Lower thermal expansion
Thermal expansion is approximately 8 times lower than all-plastic pipes and is similar to the expansion in metal pipes.

Ideal solution in areas subject to earthquakes
It is the ideal solution in areas subject to earthquakes thanks to the excellent mechanical properties such as flexibility and the capacity to alleviate vibrations.

Light in weight
The pipes are extremely light in weight as compared with metal pipes: weight is 1/3 of a similar copper pipe and is 1/10 of a similar steel pipe.

Wide range of diameters
Wide range of diameters from De 14 mm to De 90 mm

Pexal® and Mixal® are produced with materials that can be completely recycled, which, at the end of their service life can be recovered. The production processes used are energy efficient and are of a low environmental impact; in terms of the environment and conservation of resources, Pexal® and Mixal® are in line with Green Building principles.
Pexal® multilayer system is suitable in renovations as well as new buildings such as shopping centres, hospitals, offices, schools, multistorey residential buildings, and industrial plants.

Thanks to their excellent qualities they can be used in surface mounting for any type of system:
- supply of high and low temperature water to radiators;
- supply of hot and refrigerated water to fans;
- distribution of hot and cold water;
- radiant floor, wall and ceiling heating and cooling systems;
- central heating stations;
- distribution of compressed air;
- laboratories, technical and industrial plants in general.
A solution for all requirements
The range is composed of pipes supplied in straight lengths (up to diameter 90 mm for the Pexal® pipe) and in coils (up to diameter 32 mm) of various lengths, from 50 m up to 200 m.
The Valsir multilayer pipes can also be supplied with a protective corrugated covering, either in red of blue and can be pre-insulated with a flame retardant layer in grey, blue or red.
The numerous solutions provided with the different types of fittings allow all system requirements to be satisfied, providing a wide choice of manifolds, valves, accessories and anchor clips.
Metal and techno polymer fittings for all systems requirements
Accessories for all requirements.
A wide range of accessories and special components complete the system in order to meet all system requirements.
Modular manifolds with and without interception valves, coplanar manifolds, manifolds with shut-off valves, in-wall ball valves, fixing plates for sanitary appliances and many other items provide several solutions for all types of systems whether they are heating, cooling, water supply, or for the distribution of compressed air or industrial systems
