Creep analyses of a steam pipe system
Abstract
Elastic pipe stress analyses are frequently performed tocheck that the stresses in pipe systems are allowed. Foroperation in the creep range such analyses may describethe stress distribution in the beginning but not aftercreep relaxation starts to take place. In the presentwork effects of creep are considered. A pipe system ofP22 material that had been analysed by software forelastic analysis was also modelled for creep. By use oftabled creep data the following was studied: - Creepstress relaxation in the pipe system, - The effects ofstarts and stops on stress and strain distributions, -Creep in T-pieces with super imposed system stresses fromthe pipe system creep analysis. The creep properties of avirgin weld and a service exposed weld were determined byimpression creep testing. The tests were performed in theparent metal, different parts of the HAZ and the weldmetal. A weld was included in the model and analysed withthese data. Resulting creep strain distributions fromanalyses with tabled and present creep test data werecompared to each other and also to actual creep damagethat was observed in components from the system.
