Gas Corrosion of Pyrolysis Furnace Coils

Abstract:

The dependence of the rate of gas corrosion of high-alloy steels on temperature is investigated in this article. High corrosion resistance of steels is achieved by introducing into their composition of elements that form thin and strong oxide films on its surface. The most effective alloying elements are chromium, aluminum and nickel. Steel, containing these elements, becomes resistant to gas corrosion at high temperatures. Steels, containing less chromium, are susceptible to gas corrosion to the same extent as carbon steels. The steel 310 S and 316 Ti were tested for heat-resistance. Samples of steel 310 S were cut from a new pipe and from the coil of pyrolysis furnace, which was used for 6800 hours. Tests were carried out at 500 ... 1000 °С. It is established that steel 310 S is more heat-resistant than steel 316 Ti. It is shown that the heat-resistance of steel 310 S decreases after operation in the pyrolysis furnace and has lower values than values of the new steel.
