| Resumen: | 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). |
