Description of 25/30512402 DC 2025

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 and .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; For special surveillance systems it can be important to have additional training.preparatory works for joint casing system installation; - assembling weldable joint casing system;executing hot gas welding and hot gas extrusion weldingverifying 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).
