Microstructure and Property Analysis of Furnace Pipe Used over a Design Cycle

Abstract:

The state analysis and evaluation of the furnace pipe including of riser pipe, collecting gas pipe run over service period by EPMA, dye penetration inspection, macro and microstructure analysis, mechanical properties at room and high temperature and high temperature rupture property. The results show that the chemical composition meets the technical requirements, Macro-and microstructure are good, corrosion of inside and outside surface is minor, the remaining life of pipe analyzed is longer by fitting extrapolation of data of rupture property in the L-M curve. It is good proposal to production enterprises that higher level of material is selected to reduce the wall thickness properly, expand the diameter and improve efficiency.
