Multilayer pipe SDR 7.4

Alfaidro NOFIRE Multilayer Pipe (FASER SDR 7.4) is the alternative to metal systems in the fire protection sector. The PP-RCT pipe with a special flame retardant additive has a glass fibre middle layer that gives the pipes greater dimensional stability. In fact, one of the main advantages of NOFIRE pipes is the reduction in linear thermal expansion, which translates into a reduced amount of bracketing (-30%) and therefore reduced installation time and costs in wet sprinkler systems.

FASER SDR 7.4 multilayer pipe is self-extinguishing and particularly suitable for fire protection systems and can be assembled with the entire range fittings of Alfaidro NOFIRE, using traditional polyfusion techniques of pocket welding and electro-welding: the fumes produced are non-toxic and are therefore not harmful to people and animals.
