What material is suitable for the heat exchange tubes at the outlet of the 15MPA ammonia synthesis tower, given the high hydrogen and high temperature conditions?
Reply #22010-04-22
It is recommended to use 12Cr2Mo, which is a pearlitic high-temperature and hydrogen-resistant steel. Its mechanical property parameters can be found in GB713-2008.
