Plastics piping systems for the supply of gaseous fuels - Polyethylene (PE) - Part 2: Pipes
Abstract
This document specifies the characteristics of pipes made from polyethylene (PE) for piping systems in the field of the supply of gaseous fuels. NOTE 1 Additional information related to the installation of PE 100-RC systems is given in prEN 1555-1:2024, Annex A. NOTE 2 Additional information about the suitability of PE pipe systems for hydrogen and its admixtures is given in prEN 1555-1:2024, Annex B. It also specifies the test parameters for the test methods referred to in this document. In conjunction with EN 1555-1, EN 1555-3, EN 1555-4 and EN 1555-5, this document is applicable to PE pipes, fittings and valves, their joints, and joints with components of PE and other materials intended to be used under the following conditions: a) a maximum operating pressure (MOP), up to and including 10 bar at a design reference temperature of 20 °C; b) an operating temperature between −20 °C and 40 °C. For operating temperatures between 20 °C and 40 °C derating coefficients are defined in EN 1555-5. The EN 1555 series covers a range of MOPs and gives requirements concerning colours. This document is applicable to three types of pipe: - PE pipes (outside diameter dn) including any identification stripes; - PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe (total outside diameter dn) as specified in Annex A, where all PE layers have the same MRS rating; - PE pipes (outside diameter dn) with a peelable and contiguous thermoplastics additional layer on the outside of the pipe ("coated pipe") as specified in Annex B. It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes.
