Investigation of carburization extent from the inner diameter (ID) of ethylene furnace tubes using non-destructive examination (NDE) applied on the outer diameter (OD)
This research project is to investigate the possibility of measuring the depth and location of carburization and metal dusting on the inside of ethylene pyrolysis tubes using nondestructive tools applied to the outer surface. A carburization test was conducted in a specially designed and manufactured HK-40 alloy tube. Ethylene pyrolysis is considered the most important process in the petrochemical industry for producing petrochemical products. Some furnace tubes used for ethylene pyrolysis often suffer severe high-temperature corrosion since the tube surfaces are heated up to about 1,100 0C in ...
