Now this is an Expansion Joint !  This replacement Fluid Catalytic Cracking Regenerator Standpipe Expansion Joint, coming in at 32.5 feet long, 62 inches in diameter and weighing over 61,000 pounds, was shipped earlier this year to a North American refinery.  Bachmann converted and upgraded the existing hot wall design to a cold wall.  The design also included pantograph linkage to equalize bellows movement, slotted hinges to carry weight of the center section and gimbal box with pinned end spool connections to allow for out of plane lateral movements.


Unit includes 2 ply metal bellows made with Inconel 625LCF
