With its excellent acoustic properties of PEX tube ASTO obligation in the first phase of its thick-walled construction, as well as its special molecular structure and high density astolana, material fittings and pipes is 1,9 g/cm3. Thus, these tubes are able to muffle both air and mechanical noise.
His contribution to the sound insulation also makes Shaft Coupling, which is a connecting element between the PEX pipes ASTO. It increases the distance between PEX pipe and follow the system up to 3 m (distance of the mechanical noise).
ASTO Pipes are resistant to hot water and meet the requirements of DIN EN 12056 and related standards DIN 1986 part 100, ie 95 ° C for short-term loads and 90 ° C under long-term loads, as well as the requirements of DIN 4109. They can be used for waste water with pH value ranging from 2 to 12 and therefore suitable for removal of water from home, from roofs, land and bridges.
