Welding Neck Flanges - PN16 and PN40

Welding neck flanges in carbon steel for butt welding, compliant with UNI standards. The tapered neck allows a gradual transition from the flange thickness to that of the pipe, reducing stress concentrations at the weld point. They are the most reliable flanges for high-pressure and high-temperature applications.

Technical specifications

  • Type: welding neck flange for butt welding
  • Material: carbon steel
  • Nominal pressures: PN16 (ref. UNI 2282) and PN40 (ref. UNI 2284)
  • Available nominal diameters: DN 10, DN 20, DN 40, DN 65, DN 125, DN 150, DN 200
  • Tapered neck for gradual transition to the pipe
  • Drilling and dimensions according to UNI standard

Applications and uses

  • Pressure and high-temperature systems
  • Steam and hot fluid pipework
  • Petrochemical and process plants
  • Boiler rooms and critical industrial plants
Note: PN40 flanges are available in diameters DN 20, DN 150 and DN 200 for applications with higher operating pressures. PN16 flanges cover diameters DN 10, DN 40, DN 65, DN 125 and DN 200.
