FCC Spent Catalyst Standpipe Expansion Joint for US Refinery
Fluid catalytic cracking (FCC) process is a core and critical process in many refineries. It converts, inside a reactor, hydrocarbon fractions of petroleum crude or heavy oils into more valuable gasoline, olefinic gases, and other products.
Expansion joints used in FCCU service combines high temperatures and corrosive and abrasive medium and therefore they are considered highly engineered units and one of the most critical and complex types of expansion joints to be manufactured.
