Neckless Flange

Neckless flange

The neckless flanges slide on the pipe without reaching the contact plane, to which it joins by means of internal and external weld beads.

Its mechanical resistance and fatigue conditions are good, but inferior to flanges with neck, whose replacement by the flange occurs when the working conditions are less demanding.
