PEX-a pipe

We manufacture PEX-a pipes with or without EVOH oxygen barrier (3 and 5 layers) according to the European regulation EN 1264-4 by adding a ethyl-vinyl alcohol copolymer layer that prevents the permeability of the tube to oxygen diffusion, eliminating the problem of oxygen supply to the water flow and corrosion in the metal elements of the installation extending its lifetime.

Achieving an average 75% of crosslinking degree during the manufacturing process (higher degree does not mean better product), our technology does not need further treatments and is the only process that guarantees an excellent crosslinking uniformity along the pipe (maximum difference of 0.5%) providing major traction and pressure resistance, better stability under extreme temperature conditions, more flexibility and chemical resistance to solvents, oils and water without incrustations, corrosion or aging.

Our PEX-a crosslinked polyethylene pipe is manufactured using the Organic Peroxide method, having as a result the highest quality PEX pipes on the market and being Certified by the main European Institutes (AENOR, SKZ, CSTB, IIP) complying with the UNE-EN ISO 15875 European regulations and ISO 9001.


Easy Installation: No welding or mechanization required as the fittings system gives simplicity and optimizes the costs.

Flexibility: Higher flexibility than other PEX pipes. Can be easily bent and curved in cold without special tooling, saving unions and installation time.

Temperature resistance: Allowing temperatures up to 95°C and even 110°C for short periods.

Pressure resistance: The high crosslinking degree provides more than 50 years lifetime durability.

Resistant to corrosion: Suitable for corrosive fluids transportation.

Minimal pressure losses: Much lower roughness than metallic pipes reducing energetic consumption and allowing a higher flow with the same internal pipe diameter.

No deposits: Layers very resistant to calcium, dirt and substances derived from galvanic corrosion.

Lightness: It weights 7 times less than copper and 13 times less than iron on equivalent diameters.

Excellent sanitary conditions: It does not modify the organoleptic characteristics of drinking water and the corrosion absence avoid proliferation of bacteria.

Thermal, Electrical and Noise Insulator: Providing energy savings by reducing heat losses.

Frost resistance: It prevents condensation, reducing the freezing process.

Suitable for seismic zones: Because of its elasticity can absorb higher stress than metal pipes.

Thermal memory: Recovering the original shape when hot air is applied allowing to be repaired.

Multilayer pipe

Our PERT-AI-PERT Multilayer pipe is composed by 5 layers using the butt welded system to deliver the highest quality and it is Certified by the most prestigious European Institutes (SKZ, AENOR) complying with the UNE-EN ISO 21003 European regulations and ISO 9001.

The combination of PE-RT and Aluminum provides excellent properties, obtaining the advantages of both materials:  Plastic (flexibility, corrosion, low thermal conductivity) and Metal (low linear expansion, pressure, and temperature resistance) eliminating disadvantages.

1- PE-RT inner layer: Polyethylene with high temperature resistance, according to the regulation UNE-EN ISO 21003.

2- Adhesive layer: Specially designed to paste plastic with metal, with a melting point higher than 120ºC.

3- Special butt welded Aluminum alloy designed for pressurized water pipes:  Perfect pipe symmetry for Fitting adjustment and major mechanical uniform resistance to water pressure and bending stress (the welded point is the strongest point of the aluminium layer).

4- Adhesive layer: specially designed to paste plastic with metal, with a melting point higher than 120ºC.

5- PE-RT outer layer: Polyethylene with high temperature resistance, according to the standard UNE-EN ISO 21003

Corrugated pre-sleeved pipe (Simple & DUO pipe in pipe)

We manufacture Simple & DUO Corrugated pre-sleeved pipes with multiple diameters according to CSTB standards. The Corrugated protects with a minimal resistance compression of 450N the PEX-a and Multilayer PERT-Al-PERT pipe installations, allowing a fast and easy replacement on buried installations and differenciating hot and cold pipes.
