District heating and district cooling pipes - Bonded single and twin pipe systems for directly buried hot and cold water networks - Qualification testing of fitter
Abstract
This document specifies the methods of examining the knowledge and skill set of the fitter 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 13941‑2. The application of these specified methods specifications ensures that the examination is carried out according to a standardised examining procedure. This document covers 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. — preparing work for joint casing system installation; — assembling sealable joint casing system; — verifying joint tightness (leakage testing); — thermally insulating the joint casing (PUR foaming or half-shells); — sealing fill & vent openings (weldable or sealable plugs); — assessing overall installation quality of the completed joint connection (non-destructive).
