PE 100 RC BarrierAI-G Type 3 Pipes for Gas

PRODUCT DESCRIPTION

PE100-RC triple-layer piping (Type 3 – BARRIER) for pressurized natural gas and hydrogen transport, consisting of a solid-wall inner core pipe, an intermediate aluminium barrier layer and an outer protective polyethylene layer.

The solid-wall inner pipe:

–              is made of black high-density polyethylene (PE100-RC) with co-extruded orange stripes

–              is manufactured using a homogeneous resin with enhanced resistance to slow crack growth mechanism (RC), in compliance with the (UNI) EN 1555-2 standard and the DIN PAS 1075 technical specification (Type 3)

• bears product conformity marks in accordance with the standard and technical specification mentioned above
• has a third-party laboratory verified hydrogen permeability rating, confirming suitability for gaseous hydrogen blends up to 100% concentration as referenced in (UNI) EN 1555-1
• features continuous metric marking, including all information required by the relevant standards and technical specifications for Type 3 pipes, such as conformity marks and code for the raw material used.

The PE100-RC pipe is encased in a barrier layer consisting of a double-layered adhesive aluminium foil, applied as strips with a 50% overlap; this layer can be removed to facilitate the preparation of joints for butt fusion or electrofusion welding with fittings. The barrier layer reduces the slight permeation of gases, including hydrogen, through PE pipe walls, significantly improving network efficiency. The aluminium barrier is jacketed by an extruded orange polyethylene protective layer with green identification stripes. Outer layer marking mirrors the core pipe marking at every metre.

ADVANTAGES

HYDROGEN READY: polyethylene core pipe independently tested and verified for gaseous hydrogen blends up to 100% concentration in accordance with (UNI) EN 1555-1
NETWORK EFFICIENCY INCREASING: the aluminium barrier drastically reduces gas permeation and fugitive emissions through the pipe wall
RESILIENCE & SAFETY: enhanced resistance to improper handling and accidental site damages 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: outer protective layer shields the aluminium barrier and core pipe against surface damage
RELIABILITY & DURABILITY INCREASING: premium raw material formulation (PE100-RC) 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
