District heating and district cooling pipes - Bonded single and twin pipe systems for directly buried hot and cold water networks - Part 2: Qualification testing of PE-Welder; German and English version prEN 18213-2:2025
Abstract
This document specifies the methods of examining the knowledge and skill set of the PE-welder required to carry out on-site joint casing connections on thermally insulated single and twin pipe systems for directly buried hot and cold water networks according to EN 13941‑1:2019 and EN 13941‑2:2019. The application of these specified methods specifications ensures that the examination is carried out according to a standardised examining procedure. This document applies to the following processes: — preparatory works for joint casing assembly; — assembling and testing the elements for surveillance systems; NOTE For special surveillance systems it might be necessary to have additional training. — preparatory works for joint casing system installation; — assembling weldable joint casing system; — executing hot gas welding and hot gas extrusion welding — verifying joint tightness (leakage testing); — thermally insulating the joint casing (PUR foaming or half-shell); — sealing fill & vent openings (weldable plugs); — assessing overall installation quality of the completed joint connection (non-destructive).
