Description



Welding Neck Flange

Weld Neck Flange features a neck extension and weld bevel. Provides a natural form connection ideal for larger, high-pressure applications.


Blind Flange

Blind Flange has no bore or inner diameter. They are often altered to include NPT threads or custom bore holes to function as hubless Slip On flanges.

Lap Joint Flange

Lap Joint Flanges are intended to saddle over a stub end fitting. They feature an extended hub and a machined radius at the base of the flat face.

Slip On Flange

Slip On Flange is designed to accept the pipe into the center/bore, allowing welding around the outer diameter of the pipe.

Socket Weld Flange

Socket Weld types have a socket to insert pipe when space limitations make Weld Neck flanges difficult to use.

Threaded Flange

Threaded Flanges contain a female NPT threaded center for connection to male threaded piping. These flanges are commonly implemented in reducing connections.
