Boiler Bank Tubes

Boiler bank tubes are bent to shape tubes or steam generating tubes where water is converted to steam. Boiler bank tubes carry a mixture of water and steam. Fabricated from tubes in various sizes and shapes, bending of these tubes is generally to larger radius hence they need some tube bending expertise to avoid wrinkles, surface cracking, irregularities, ensuring long life of tube resulting in smooth and efficient operation of the boiler.
boiler bank tubes connect steam and mud drums in a boiler. Natural circulation occurs with out the aid of any external down comers. First 20-30% rows act as risers and the rest act as down comers. Membrane division wall separates the boiler bank and the furnace. Drum coil heaters are provided in the lower drum to preheat the feed water before sending it to economizer.
we manufacture boiler bank tubes with or without fins with swaged (reduced diameter) ends are manufactured by us. We have a special purpose swaging machine which gives accurate thickness and concentricity of swaged tubes.
these bank tubes for replacements in boilers have been supplied by us to various industries like sugar, refineries steel plants, small and large utility / captive power plants. These shaped tubes are generally fabricated from seamless/ erw tubes. The sizes of tubes having different shapes vary from 114mm od. X 4 mm thk. To 50. 8 mm od. X 5. 60mm thick with or without swaged ends and with or without welded fins and with wrap around /man hole bends.
