Abstract:

This paper introduces the failure mechanism of TP304H pipe, and compares its high temperature performance with those of several typical heat-resistant steel. Combined with the working condition characteristics of high temperature steam pipes in convection coil of cracking furnace, the material selection method and principle are proposed. The specific working conditions of P91 replacing 304H are provided.

Key words: cracking furnace, convection coil, failure, material selection
