The pipe consists of 3 layers bonded into a single unit. The HDPE outer layer provides protection and UV resistance. The central edge is welded to an aluminium layer providing high stability and an effective oxygen barrier, whilst the inner PE layer provides extreme resistance to limescale – significantly enhancing hygiene. Most Mepla pipe sizes can be bent, creating the opportunity to reduce fittings and hence lowers the overall installed cost. The system is suitable for an operating pressure of up to 10 bar and operating temperature of up to 70°C.
