The threaded flange is similar to the slip-on flange, but the bore is threaded. Its cheif merit is that it can be assembled without welding, explaning its use in low pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding create a hazard.

Threaded flanges with a hub have published specifications that range from 1/2" thru 24".  JH STEEL provides threaded flanges in all material grades, specifications and sizes.
