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.
