Steel studs are welded onto the base tube. Studded Tubes Type of Studs Cylindrical , elliptical or lens type.
Studded Tube(Welded Stainless Tube) Advantages:
1)Satisfying connection surface, little heat loss .
2)Welding connection rate higher than 90 percent.
3)No need of welding power, hardly any welding tumor .
4)Narrow heated zone on the surface, no melted pool, without destroying the tissue of basic tube.
5) Welding parameters are strictly set to ensure the quality of bulk Studded Tube and avoid the instability of manual operation.
Studded Tube(Black Welded Pipe) Properties:
It occupies less space and is compact.
Highly durable.
Studded Tube(Weld Galvanized Pipe) Applications:
Studded tubes and studded pipes are widely used in heat recovery applications of petrochemical plants,oil&gas and chemical processing, mostly in areas of convection ovens, at very high temperature and harsh environments where corrosive elements such as sulfuric acid could be present.
