DIN 2634 PN25 Welding Neck Flange

May .14.2026

DIN 2634 PN 25 Weld Neck Flanges are generally used in high pressure applications, where hot or cold temperatures exist.

DIN 2633 PN16 Welding Neck Flange

May .12.2026

DIN 2633 PN16 Welding Neck Flange

DIN 2632 PN10 Welding Neck/WN Flange Dimensions

May .07.2026

DIN 2632 PN 10 Weld Neck Flanges are generally used in high pressure applications, where hot or cold temperatures exist. These steel DIN 2632 weld neck flanges are circumferentially welded into the system at its neck which means that the integrity of the butt welded area can be easily examined by radiography.
