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. |
