摘要：
Creep testing has been made on a service-exposed header of 2.25Cr1Mo steel. Four series including parent metal, weld metal and cross-weld combinations were studied. A metallographic investigation of cavitation development on ruptured samples has also been performed. A model for the stress state in a thick-walled welded pipe has been derived. Results obtained from creep testing and metallographic investigation have been analysed and compared with the model.
