Abstract: To evaluate the performance of the P92 steel pipe as made with the CC billet，three P92 large-sized，heavy wall steel pipes provided by a couple of domestic steel works are subjected to physical and chemical tests，and high temperature creep rupture test at 625 ℃. As a result it is revealed as follows. All the physical and chemical properties of the CC billet-made P92 steel pipe are in compliance with applicable standard requirements. The 100 000 h extrapolated high temperature creep rupture strength at 625 ℃ is 93.1 MPa，which is higher than the recommended value in ap- plicable specification. The CC billet-made P92 steel pipe has met the engineering application condition，and thus the cost of the industrial chain can be reduced.
