A boiler gets hot, really hot. And when it does, the walls expand.
To help control expansion, one solution is to cut slots in the walls and weld “Expansion Folds” over top of these slots.
This gives the plate a little more room to expand as the pressure builds in the unit. They are placed around the plate helping it expand as it heats.
How safe do your employees feel working on your old, outdated platforms? Are they still up to code?
Replace those aging, rusted, dangerous platforms with new solid units from Riggs.
Getting Your Materials from Point A to B!
Everyone’s Hoppers and Chutes are a bit unique. They have to fit back in place just right. Getting that fit correct is something we know at Riggs.
A new custom replacement for a worn out unit or a rebuilt will fit like a glove. Access doors, cleanouts and manways back where they need to be.
You’ll be happy you chose Riggs.
Used during testing and turnarounds, the Target Blind is another example of the specialty blinds Riggs custom designs.
There’s a reason companies choose Riggs for their custom blind work. With other places, if it’s not on the shelf, they just can’t help you. That’s not how we work.
This Target Blind is the perfect example of that. From Spectacle Blinds with machined finishes to Double Bleeders with welded valves. “Not on the shelf” is never an excuse at Riggs.

As original steel guards deteriorate and go out of service …
They become dangerous to work on when removing to repair fans, bearings and shafts.
These new aluminum replacements designed by Riggs Machine are lighter and easier to handle (especially for the size!)
This means unit maintenance is faster, safer and more cost effective.
This specialty item was fabricated from the ground up at Riggs.
We designed the electrical system and the hydraulic system. We have the technical staff to design and build units like this.
These custom units are used in refineries across the country. Riggs even designed the operation manuals for the units.
