Technical Informations
Spiral winding of extruded HDPE bands over heated steel mandrel, simultaneously winding of HDPE coated profiles over the band joining places as well as conduction of this process at the melting temperature of PE materials provide FKS pipes to have a completely homogenous fusion.
FKS pipes are produced according to TS 12132 and DIN 19661-1 and DIN 16961-2 standards.
