WELD NECK FLANGE
Our most frequently requested flange, the Weld Neck Flange features a neck extension and weld bevel. Provides a natural form connection ideal for larger, high-pressure applications.
SLIP ON FLANGE
A simple alternative to the Weld Neck flange, a Slip On Flange is designed to accept the pipe into the center/bore, allowing welding around the outer diameter of the pipe.
BLIND FLANGE
Designed to cap off a line, a 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.
SOCKET WELD / COUNTER BORE FLANGE
Sometimes referred to as Counter Bore flanges, the Socket Weld types have a socket to insert pipe when space limitations make Weld Neck flanges difficult to use.
THREADED / COMPANION FLANGE
Threaded or Companion Flanges contain a female NPT threaded center for connection to male threaded piping. These flanges are commonly implemented in reducing connections.
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.
