Pyrolysis Heaters

Pyrolysis heaters are similar to steam/methane-reforming heaters. The same materials are often used for both. There are a few notable differences. Both Ys and U-bends are used in pyrolysis heaters and suffer erosion. The reaction in the tubes is usually carburizing and requires that the surfaces be smooth from boring or honing and that the material be more resistant to carburization. The material used in pyrolysis heaters is often a modification of a high-strength material that is adequate in reforming heaters.
