Take these worn boxes that attach to the sides of boilers. We needed to reuse some of the components, but build new, stronger frames.

These new Boiler Boxes will fit just like the old ones, but last a lot longer.

Boiler Face Plate w/Expansion Folds

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.

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.

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.
