Abstract


This paper presents the results of research on the high temperature behavior of assemblies obtained by crimping copper pipe fittings used in natural gas supply installations. For the realization of this study, 18 specimens were made by crimping copper pipe fittings with outer diameters De = 15/18/22 mm and wall thickness wt = 1.0 mm. All 18 specimens were tested at elevated temperatures using the facility developed by the authors. The specimens were charged with nitrogen at a pressure of 5 bar, and placed inside the oven at a temperature of 650 °C for 30 minutes. The results obtained confirm the reliability of the crimping technology for use in natural gas supply installations, ensuring tightness under extreme conditions.
