Product Profile of Studded Tubes and Studded Coils
TubeWeld [India] Limited supplies Studded Tubes and Studded Coils. TubeWeld [India] Limited manufactures a range of industrial boiler plants. The Studded Tubes and Studded Coils are used in Fired Heaters under Very High Pressure & Temperature mainly in Petroleum refineries.
Specifications of making Studded Tubes and Studded Coils are:
An electric current is applied by contacts on the stud and tube and the studded coils resistance in this circuit produces the heat necessary for welding.
Maximum resistance and therefore maximum heating occurs at the interface between the Stud and the tube.
Pressure to forge the Stud and the tube together at the point of maximum heating is applied by various forms of tooling.
These resistance welding processes produce a strong metallurgical bond between the stud and the tube while minimizing the heat affected zone [HAZ] in the tube.
The use of pressure to forge the fin and the tube together helps to minimize the heat input necessary to make the weld.
This Product is studding of pipes up to 8 inch diameter and stud diameter up to 18mm can be supplied in carbon steel, alloy steel and stainless steel pipes.
