Shell Furnace Tube Repair

Replacing part of the front and rear outer casing and part of the furnace tube on this unit involves careful planning and preparation between BTH Kettle Service and the client. Cracked welds, infusion soils, inter-dab voids, or inclusive plates are some of the reasons for boiler failure. The failure in this case was due to a toe crack in the inner filet weld, which we found to be the most common fault of all.

to perfectly realign the burners when they are re-placed in critical positions, so as not to cause flame impingement in the repaired furnace bath. Weld a ‘J’ type around each end of the tube to a depth of 3ml in addition to the thickness of the tube as specified in BS 2790.

Combustion chamber tube plates after being diluted and engine ‘J’ prepared. These tube plates are subjected to magnetic particle inspection (MPI) as part of the quality assurance procedures used by BTH and by many leading Insurance and Inspection authorities.

Method used to reduce the thickness of the combustion chamber tube plates, to allow faster heat transmission through the combustion chamber tube plates, reducing the problem of cracked tube plates and tube ends. Mirror finish and tube end radius ensure less heat at the tube ends.


All welding is performed by highly skilled welders to the highest standards. At BTH Kettle Administrations Ltd we take pride in the finished product. It is the skills of our welders that allow us to maintain the highest standards. All of our welders are coded for the list below:

BS EN ISO 15614 Part 1
BS E NISO 15614-8-2002
47BS EN 287-1-A1-2008
