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.
