Already many years, Schelde Exotech is a specialist with Internal Bore welding of tube-tubesheet welds for the chemical industry. An internal Bore tube-tubesheet weld is the solution when crevice corrosion can be a problem. Schelde Exotech is experienced with welding several alloys.
Two years ago we developed in-house our own internal bore weld for Waste Heat Boilers. Using this Internal Bore Weld on the inlet side extends the lifetime of the tube-tubesheet weld and thus reduces maintenance costs
Last year we successfully fabricated the first Waste Heat Boiler with the Internal Bore weld to be used on a refinery. This year we are re-tubing an existing WHB with introduction of the Internal Bore Weld.
