Studs are automatically welded to the base tube using electric resistance welding machines controlled by PLC programming. Our proprietary automatic stud feeder technology ensures consistent welding quality and production efficiency.
- Base Tube Materials: Carbon Steel, Low Alloy Steels, Stainless Steel
- Stud Types: Cylindrical, elliptical, or lens configurations
- Heat exchange efficiency equivalent to 2-3 times that of bare pipe
- Enhanced cleaning capability for dirty flue gas environments
- High rigidity for extreme temperature and pressure conditions
- Reduces bare pipe usage (1 studded pipe replaces 4-10 bare pipes)
- Ideal for harsh environments with temperature extremes and corrosion
Furnaces, chemical processing plants, petrochemical facilities, power stations, and boilers where liquid media under high pressure require heating or cooling in corrosive environments.
Comprehensive quality control throughout production including raw material inspection, dimensional verification, water pressure testing, and strength testing with mill test certifications for all components.
