Multi-layer co-extruded barrier high-density polyethylene pressure piping systems engineered specifically for contaminated ground, refinery brownfield corridors, and areas with high risk of organic hydrocarbon and chemical permeation. Compliant with ISO 21003, EN 12201, and WIS 4-32-19 standards, featuring a specialized five-layer composite structure: an inner virgin PE100 drinking water core, an adhesive tie layer, an impermeable solid aluminum or EVOH (Ethylene Vinyl Alcohol) continuous diffusion barrier, a secondary bonding layer, and an outer protective PE100/PP protective casing. Provides an absolute, 100% impermeable barrier that prevents volatile organic compounds (VOCs), benzene, toluene, MTBE, fuel oils, and agricultural pesticides from permeating through the plastic pipe wall into municipal potable water supplies. Available in outside diameters from OD 32mm up to 800mm across pressure classes PN10 to PN25.

Potable water pipelines traversing oilfield concessions, refinery brownfield zones, gas station perimeters, chemical processing plants, airport fuel storage zones, and industrial contaminated land across Basra, Zubair, Kirkuk, and Baiji.
Conventional polyolefin materials, including standard PE100, are semi-permeable to low-molecular-weight non-polar hydrocarbons, chlorinated solvents, and petroleum fuels. When standard plastic pipes are buried through brownfield industrial ground, refinery proximity zones, or near fuel filling stations, volatile organic compounds can diffuse through the pipe wall at a molecular level, contaminating municipal potable drinking water with hazardous carcinogenic substances. Co-extruded multi-layer barrier PE100 pipes solve this critical vulnerability through an integrated, continuous metallic aluminum foil or high-barrier EVOH diffusion barrier layer, manufactured and tested strictly in accordance with WIS 4-32-19 and EN ISO 21003 specifications.
The mechanical performance of barrier PE100 pipe matches or exceeds standard PE100 while adding absolute chemical containment. The inner core consists of 100% virgin drinking-water-approved PE100 with smooth hydraulic characteristics (Hazen-Williams C = 150). The central aluminum layer is helically or longitudinally overlap-welded, providing zero permeation to hydrocarbons, chlorinated hydrocarbons, and toxic industrial solvents under test conditions according to ISO 17456. The external protective skin shields the barrier layer against mechanical scratching during pipe installation and UV degradation during open-air storage. Specialized sealed electrofusion fittings and barrier mechanical adaptors ensure that the barrier layer remains continuous across all joint interfaces without chemical bypass.
Across Iraq’s primary petroleum provinces—including Basra, Zubair, Missan, and Kirkuk—infrastructure pipelines frequently intersect oilfield concession boundaries, refinery wastewater corridors, and legacy hydrocarbon-soaked soils. Installing standard polyethylene pipes in these zones presents severe public health hazards and pipeline swelling failures. Our barrier PE100 systems provide certified, permanent protection for municipal potable water supply lines traversing contaminated oilfield corridors, ensuring pristine water quality for communities throughout Iraq.
Standard polyethylene has a non-polar polymer structure that allows volatile organic hydrocarbons (such as benzene, gasoline, and diesel) to slowly permeate through the wall into drinking water, causing toxic contamination and chemical swelling that compromises structural integrity.
Barrier pipe systems utilize specialized electrofusion fittings featuring integrated elastomeric barrier sealing rings that completely encapsulate the cut pipe ends, ensuring the aluminum barrier layer is continuous and isolated from chemical contact.
Yes. Because barrier PE100 pipes feature a continuous metallic aluminum inner layer, they can be located directly using standard electromagnetic pipe locators without needing an auxiliary external tracer wire.
