Studded Tube

Welding Process 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 38mm to 273 mm(1.5" to 10") o/d and stud diameter from 6mm〜25.4 mm(0.23" to 1"). 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. Production Capacity Total four(4) PLC automatic ERW studding lines, monthly production capacity is 5,000,000 studs in total. The automatic stud feeder was developed by our engineers combining both our large experience manufacturing extended surface and the most modern control technology available in the market. The technology has benefited us with more efficient production and consistent welding quality.
