WELDED FIREBOXES

We have manufactured all shapes and sizes of welded firebox for over thirty years. We have built up a large quantity of firebox endplate and wrapper tooling to enable us to hot form both endplates and wrappers.

Our Flanged and Butt Welded Fireboxes are built to the latest Insurance standards. Each firebox is viewed by insurance surveyors at various points during its manufacture, and is finally 100% NDT tested to prove there are no flaws in the welding. Certification is supplied on completion.

CASE STUDY: WELDED FIREBOX
CLIENT: BARRACKS STEAM MUSEUM, ABERDEEN Traction Engine Rebuild
JOB: MANUFACTURE OF FLANGED & BUTT WELDED FIREBOX

SCOPE OF WORK
Careful dimensions are taken from the original firebox, and plate sizes are ascertained before being ordered.  Once we have the new boiler plate, we press two new firebox endplates and hot form the wrapper over a curved former.

The two endplates and wrapper are then prepped for welding by grinding a bevel onto the plate edges, the box is then tack welded together before being checked by the insurance surveyor. Once given the all clear it’s then fully fusion welded by our coded welders. In this case the foundation ring and firedoor ring were re-usable so were seal welded to the box. A new set of roof girders were manufactured and stay bars machined and fit.
