Polyethylene (PE) pipes are ...

Polyethylene (PE) pipes are best suited for long life times (dependent upon the conditions, >100years). Low maintenance, lightweight, flexibility, leak free systems and ease of installation are key characteristics. Most importantly PE pipes are corrosion free. Depending on the diameter, very long lengths can be supplied minimising the need for jointing. If jointing is required, this can easily be done through butt fusion welding or by using electrofusion fittings. This modular approach also gives the opportunity to to easily tap off the main flow pipe if required. New modern PE 100 products such as "crack resistant" grades may also be used in grounds where imported back fill is not required. As indicated previously, good quality PE resin suppliers and pipe manufacturers comply with various national and international standards to ensure products that are fit for purpose. As a minimum, ISO 4427 gives more details. As a rough guide, a good quality PE 100 SDR11 pipe can transport water safely at 16 bar (safety factor included), based on an ambient temperature of 20°C for 50 years.

I hope this helps a little !
