Pexal® is a WRAS approved multi-layer pipe offering various applications: from the distribution of hot and cold drinking water to centralised water supply systems, from radiator systems to radiant floor, wall and ceiling heating and cooling systems. Whether you're an architect, specifier, consultant or plumbing technician, Pexal® can help you deliver a superior job. Just take a look at the difference specifying, choosing and installing Pexal® can make:
- Resistance to corrosion
The total resistance to corrosion, to construction materials and the main chemical compounds allow it to be used in a wide variety of applications, both residential and industrial.
- Excellent flexibility
The combination of cross-linked polyethylene and aluminium guarantees excellent flexibility when bending (also when bent manually) and dimensional stability in the long term.
- Excellent acoustic insulation
The elastic nature of the cross-linked polyethylene allows excellent absorption of vibrations and therefore an excellent acoustic insulation.
- 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.
- 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.
- Wide range of diameters
Wide range of diameters from De 14 mm to De 90 mm.
- 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
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 techno-polymer to cover different system applications.
The Pexal® Difference.
The Advantages Of Plastic Materials & Metal In One Product:
A solution for all requirements
The Pexal® system is manufactured in compliance with the European Standard EN ISO 21003 and its characteristics of reliability and quality are guaranteed by the most severe certification bodies that control and verify product performance with meticulous frequency within the manufacturing plants
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.
An important trait of Pexal® multilayer pipes is that they combine the advantages of synthetic materials and in particular, those of crosslinked polyethylene, such as a high resistance to abrasion, corrosion and chemical agents, and a high standard of hygiene, with those of aluminium, such as an excellent resistance to high temperatures and pressures, dimensional stability, an unequalled barrier to oxygen and light and a low thermal expansion.
