PE 100 RC BarrierAI-G Type 3 Pipes for Gas

PRODUCT DESCRIPTION

Three-layer pipeline system (Type 3) for pressurized conveyance of combustible gas and hydrogen, consisting of a smooth solid-wall inner core pipe made of black PE100-RC high-density with co-extruded orange identification stripes. Compliant with (UNI) EN 1555-2, produced from homogeneous, fully compounded resin with high resistance to Slow Crack Growth (RC) pursuant to DIN PAS 1075 technical specification. Core pipe features continuous metre marking with full standard data, approval marks, DIN PAS 1075 Type 3 code, and raw material designation. The polyethylene core pipe 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.

The PE100-RC DCR core pipe is encased in an aluminium barrier layer made of wrapped, overlapping, adhesivebonded foil, which remains peelable for joint preparation. The aluminium barrier is jacketed by an extruded orange PE 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
