PE 100 RC+DCR BarrierAl-DCR Type 3 Pipes for Water

PRODUCT DESCRIPTION

PE100-RC DCR triple-layer piping (Type 3 – BARRIER) for pressurized water transport, consisting of a solid-wall inner pipe made of black high-density polyethylene (PE100-RC) with blue identification stripes on the outer surface. The pipe bears product conformity marks according to (UNI) EN 12201-2 norm and DIN PAS 1075 technical specification.

It is manufactured using a homogeneous resin and offers enhanced resistance to:

–           premature aging caused by chlorine-based disinfectants (DCR) – classified as Category 2 (CC2) according to PPI TN-43/2012 and tested in compliance with ASTM F2263-14

–           slow crack growth (RC) in accordance with (UNI) EN 12201-2 and the DIN PAS 1075.

The standard pipe complies with the hygienic and sanitary requirements established by Italian health regulations — as well as those of several other countries — for materials intended for contact with drinking water. The inner pipe features continuous metric marking, including all information required by the relevant standards and technical specifications for Type 3 pipes, such as conformity marks and the code for the raw material used.

The PE100-RC DCR core pipe is encased in an aluminium barrier layer made of wrapped adhesive bonded foil with 50% overlap, which remains peelable to facilitate the preparation of joints for butt fusion or electrofusion welding with fittings. The aluminium barrier layer ensures the pipe is completely impermeable to the penetration of pollutants present in contaminated or at-risk soil. The aluminium barrier is jacketed by an extruded blue polyethylene protective layer with green identification stripes. Outer layer marking mirrors the core pipe marking at every metre.

ADVANTAGES

HYGIENIC SAFETY: aluminium is impermeable to soil contaminants, making barrier pipes ideal for installation in contaminated or high-risk ground
RESILIENCE & SAFETY: enhanced resistance to improper handling and accidental site damage during storage, transport and laying, thanks to protective outer layer that preserve pipe integrity
PERFORMANCE: combined structural action of the adhered aluminium layer and outer PE sheath increases overall mechanical strength, extending service life and lowering maintenance demands
RELIABILITY & DURABILITY INCREASING: premium raw material formulation combining RC and DCR properties, meanwhile the external PE layer protecting the barrier foil and core pipe from accidental damages
TRENCHLESS COMPATIBILITY: ideally suited for trenchless installation and pipeline rehabilitation techniques
WELDABILITY: standard butt fusion and electrofusion techniques can be used once the protective outer layers are peeled back.
WEATHERING PROTECTION: core PE pipe is protected against UV radiation and weathering during outdoor storage.
