Study on Oxide-layer Drop of Inner Pipe for High Temperature Over-heater of 102 Steel
Aimed at the tube-burst accident caused by blinding off the tube because of inner pipe oxide-layer drop of 102 steel high temperature over-heater,the microstructure and composition of oxide-layer were analyzed by SEM,metallurgical microscope,EDS.From material and practical running,the reasons of the production and drop,the mechanism of inner oxidation were studied.Some methods were put forward to avoid or remit the production and drop of inner pipe oxide-layer.
