The Komfort Multilayer Pert-Al-Pert Pipe with Internal Aluminium Oxygen Barrier has a welding joint method used for welding the aluminium oxygen barrier is a overlap joint which offer a weld width area of 4 mm or wider, unlike the but welded joint which is between 0.2 to 0.3mm with such narrow weld area this method it has weaker joint.
50 years warranty and 10 years guarantee against manufacturing defects.
They are composed of an inner and outer layer of PERT, that are bonded by a special glue to the intermediate layer of aluminium. By that way, a perfect oxygen barrier is accomplished, that ensures their perfect un-ruptured connection.
They are characterised as pipes of the century, because they combine the advantages of metal pipes (small linear expansion and high mechanical strength) with the advantages of plastic pipes (flexibility, without formation of salts inside the pipe, resistance to electro corrosion, low noise level, fast and easy installation )
The Komfort tubes AL-PERT is produced according to international standards ASTM F-1282 and accompanied by a certified SKZ for their mechanical strength and warranty 2.000.000 CHF (Swiss francs).
The Komfort multilayer pipe combines the properties of a metal and plastic pipe and despite it has the flexibility of a plastic pipe and is very light weight, in parallel has strong properties and provided higher dimensional stability under high water temperature and pressure, minimum thermal expansion and resistance to degradation.”
