适用范围：This European Standard specifies requirements for joints made under field conditions between adjacentpreinsulated pipes and/or fittings in district heating networks. The specified general requirements are also valid forfield-made T-branches, bends, reducers, caps, etc.This European Standard covers jointing of steel service pipes by means of fusion welding, the connecting of casingends with joint casings and the thermal insulation with poured rigid PUR foam or prefabricated PUR-foam insulation.This European Standard specifies methods for type tests of complete joints and PUR-foam for joints underlaboratory conditions.The requirements of this European Standard can also be applied to casing pipe weldings/connections of on sitemade fittings.The requirements of this European Standard aim to obtain a technical life of the joints of at least 30 years.
