Resistance to corrosion
The total resistance to corrosion, to construction materials and to the principal chemical compounds allows it to be used in the most varied applications.
Connection between the crosslinked polyethylene and aluminium guarantees excellent flexibility during bending (also manual) and structure permanence in the long term.
Excellent sound absorption
The elasticity of the crosslinked polyethylene means vibrations are absorbed which therefore guarantees excellent sound absorption.
Reduced pressure losses
The extreme smoothness of the internal surface ensures reduced pressure losses
Service life of at least 50 years
The system has a service life of at least 50 years that is guaranteed by product standards.
The range of fittings, accessories and relative tools is particularly wide and allows all requirements to be satisfied.
barrier to the passage of oxygen
The layer of butt-welded aluminium acts as an absolute barrier to the passage of oxygen, gas and light.
Wide range of pipes from De 16 mm to De 75 mm.
Lower thermal expansion
Thermal expansion is about 8 times lower than that of plastic pipes and is similar to that of metal pipes.
Ideal solution in areas subject to earthquakes
It is also the ideal solution in areas subject to earthquakes thanks to the excellent mechanical properties such as flexibility and capacity to dampen vibrations.
Light in weight
The pipes are extremely light as compared with metal pipes, the weight is 1/3 in comparison with the weight of a copper pipe and is 1/10 of the weight of a steel pipe.
The Valsir Pexal Gas® system is produced with materials that are completely recyclable which can be recovered at the end of their service life. The production processes employed are energy efficient and of reduced impact. Valsir has adopted the Green Building principles in terms of environmental protection and conservation of resources.
