Plastic pipework is used for the conveyance of drinking water, waste water, chemicals, heating fluid and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gases, compressed air and vacuum system applications. Plastic pipe systems fulfil a wide variety of service requirements.Product standards for plastics pipe systems are prepared within the standards committee known as CEN/TC155. These requirements are precisely described in a complete set of European Product Standards for each application alongside their specific characteristics. For example: Conveyance of drinking water: Hygienic requirements Conveyance of gas: Highest Safety requirements Plastic pipes for radiant heating and floor heating: Temperature resistance over decades Sewer applications: High chemical resistance. Plastic pipes are perfectly capable of fulfilling the specific requirement for each application. They do so with a high level of performance over a long lifetime and with reliability and safety. The key factor for success is achieved by maintaining consistently high quality levels. For plastic pipe products, these levels are closely defined by the different standards.Źródło: https://en.wikipedia.org/wiki/Plastic_pipework.
