Whether you’re running a simple-cycle or combined-cycle gas-fired power plant, odds are you have to run CEMS (continuous emissions monitors). Altech Environmental (Envea) can help you look at a new system, service and old system, or build a hybrid of the two.

If you look close you can see that the edge of this heavy-wall expansion joint was cut in order to fit next to the concrete structure. They welded the flow-liner in on both sides afterward to keep it from leaking. This works, but it adds additional stress the the EJ below it, which wasn’t originally planned for.

This crude oil preheater outlet duct has 5″ of lateral offset (meaning it’s really messed up). Rather than do structural steel work to repair the offset we field-fit an expansion joint solution that would accommodate such extreme offset.

Doing an install way up high on a preheater tower downcomer at a cement plant. The old expansion joint here failed and we were called in to supervise and verify the install of the replacement that we designed for them.

This is an expansion joint that feeds a liquid mixture of ash and silica out of the bottom of a fluidized bed boiler. The ash that comes through this tied-universal bellows is between 1200-1800 degrees F. In order to handle such high temperatures the expansion joint has a refractory-lined pipe that functions as a flow-liner inside of it and is only anchored at one end, so the other can slide freely and compensate for expansion and contraction.

If you beat on your metal bellows Expansion Joints with a sledge hammer in order to try and knock the material inside loose, the metal bellows become ineffective and may as well not be there. Also, this particular metal bellows has a flow-liner (or shield) inside, so the person who hit it probably didn’t even unplug the pipe like they’d hoped to.

Cement plants are full of fans and expansion joints that see a lot of abrasive particulate. We can help you design your fans and expansion joints to last longer by using the right abrasion-resistant materials for the job.
