Professional Precision Repairs & Fabrication
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.
We Love Big Projects!
One of the most exciting projects we’ve worked on has been the Goodman Industries Radio Controlled Pot Ash Loader.
From design, to welding, electrical, hydraulics and then field testing.
Tested & Trusted
Riggs products are used in all conditions, in all type of facilities and in many different environments.
Still wondering if Riggs can handle your job?
Rebuilds and Overhauls
After years of hard service your equipment will need an overhaul. Riggs will tear down your worn machinery and rebuild it from the ground up.
Using the newest components and most modern techniques, they might run better than they have in years!
Minimal Downtime – Fast Turnaround
Though coal and coke can be hard on your equipment, Riggs’ employees work even harder to get your machinery back on-line and keeping you operating.
Better Components …
A lot has changed since many of these units went into service.
Many components are just made better than the OEMs. Better springs, rings and gaskets mean more reliable equipment.
How safe do your employees feel working on your old, outdated platforms?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.
