Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.
More
Use these heavy duty forged flanges for high-pressure applications. Bolt two flat-surface flanges or two raised-surface flanges of same size together with a gasket (sold separately) to create an access point in a pipe line.
304 stainless steel flanges offer very good corrosion resistance. 316 stainless steel flanges have excellent corrosion resistance.
Butt-weld flanges are also known as weld-neck flanges; the flange neck has a beveled end that, when flush to pipe, creates a trough for a strong weld. Slip-on weld flanges have no internal stop; slide a pipe through the flange and weld on both sides. Socket-connect flanges have an internal stop that supports the pipe when welding and prevents the pipe from sliding all the way through.
Stub-end flanges are also known as lap-joint flanges; use them with a stub-end straight adapter (not included). The stub-end straight adapter slides into the flange and welds to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily for frequent cleaning and inspecting. Cap flanges are also known as blind flanges.

Create an access point in a high-pressure hydraulic fluid line with these flanges. They are also known as Code 61 SAE hydraulic flanges. To connect, bolt a flange with an O-ring groove surface to a flange with a flat surface of the same size. Flanges are 316 stainless steel for excellent corrosion resistance.
Socket-connect flanges weld to pipe for a strong, permanent connection. Cap flanges are also known as blind flanges.
