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.
