| Dear experts, In attached images you will find the failure happened on the junctions of header to heater tubes of a natural gas + steam heater. The heater specification is as follows: Inside fluid: natural gas + steam Outside fluid : flue gas from burning of natural gas in the reformer of an Ammonia plant. Tube and header material : SA-312 TP 3047H Considering the above let me have your suggestion regarding the failure reasoning. Regards, Karandish |
