Our core competency lies in the manufacturing of boiler components and spares for very large fossil fuel fired steam boilers in thermal power plants, sugar & fertilizer industries, refineries, petrochemical, steel industries, smelter waste heat boiler, fluidised bed boilers etc..

Waste Heat Boilers

Studded tubes are used in Reheaters in refineries and in the Fluidised Bed of an FBC Boiler. The tubes are securely welded with studs to increase the surface area for better heat-transfer. Tube weld can give very closely studded tubes in High Alloy Steels using Automatic Stud Welders. The studs are welded both by an Automatic Drawn Arc Process and by Resistance Welding. On Alloy Steel Pipes Studded with Carbon or Alloy or Stainless Steel Studs both Pre & Post weld heating is carried out on line using state of the art technique.
