38 Permeation resistant pipe SLA® Barrier Pipe Permeation resistant pipe system made of PE100 RC for the protection of drinking water and the environment. Fitted with a high strength PEplus sheath. SLA® Barrier Pipe is a permeation resistant pipe system made of PE100 RC fitted with a high strength sheath and an impermeable barrier made of conductive aluminium to prevent the penetration of contaminants. The barrier provides permanent protection of both sensitive media and the environment. The conductive properties of the impermeable barrier also allow detection and stress measurement after installation to check that no damage has occurred during pipelaying. The design also allows precise location of the pipeline system, which facilitates future planning and excavation. Impermeable barrier protects in both directions SLA® Barrier Pipe has the same properties as SLM® 3.0, but is also equipped with an aluminium impermeable barrier. This barrier works in both directions so the pipe protects the transportation of drinking water when laid in contaminated ground, as well as sensitive environments where the pipe transports waste water or other contaminated substances through or near a water source, for example. The pipe’s high strength sheath is made of PEplus, with a thickness, in the case of dim 250 mm/SDR17, corresponding to 25% of the pipe’s wall thickness. SLA® Barrier Pipe meets the requirements of PAS 1075 Type 3 (pipes with a higher strength sheath). Homogeneous inner pipe in PE100 RC with wall thickness according to EN standard. Permeation resistant layer to protect both media and the environment. The pipe’s high strength sheath is made of PEplus, with a thickness, in the case of dim 250 mm/SDR17, corresponding to 25% of the pipe’s wall thickness.
