Steel studded tubes are used instead of finned tubes for heat transfer in the processing industries, generally in furnaces, gas turbines, fired heaters and furnace applictions where the surface is exposed to a very corrosive environment and where very dirty gas streams require frequent or aggressive cleaning

The steel studs are automatically resistance welded to the tube, producing high quality forge welds. Our automatic studding machines are capable of handling tube diameters from 1" TO 8" o/d and standard stud diameter of 12.7mm.

The welding process enables the combination of any grades for studs and tube: carbon, alloy, stainless steels and high nickel alloys. Alloy steel pipes are stress-relieved after studding, according to the relevant specifications for the class and grade of steel used.
