SORF

SORF Flanges are a popular type of pipe flange designed to accept pipe into the bore/center of the flange for welding around both the Outer Diameter (OD) of the pipe and on the interior side of the connection. The slip-on flange is a simple and excellent alternative to a weld neck as it does not have a weld bevel, and therefore allows the pipe to be adjusted in length relative to its position of the flange. The bore of the slip on will give ample amount of space for the matching pipe. This allows for enough working space for the welder and fabricator to make the connection.

WNRF

WNRF Flanges are the most popular flange type with a neck extension with a weld bevel at the end. This type of flange is designed to butt weld directly to pipe to provide a superior and relatively natural form connection. In larger sizes and higher pressure classes, this is almost exclusively the type of flange connection utilized. If only one bored flange style existed in modern applications, the weld neck would be your flange of choice.

BLRF

A BLRF Flange is a solid steel piece with no bore (interior diameter) and primarily designed to cap off a line. As the majority of flange connections allow for the passing through of air or fluid via an interior opening, blinds give the ends of pipe connections a well formed termination point or rerouting of the media in question towards another portion of the pipe assembly. Opt for a blind flange in these cases, as well as in instances when a pipe line requires a future modification such as the installation of a valve or fitting to reroute flow.

• Flange Face Type : Flate Face (FF), Raised Face (RF), Ring Type Joint (RTJ)

SWRF

SWRF Flanges are a less common but equally effective connection for flanges which require less overall available space than a traditional weld neck flange, with a counterbore in the center to allow for a clean weld of pipe into the socket. Usually furnished in smaller nominal pipe sizes, these make an excellent alternative to weld necks and slip ons when necessary. An assembly with limited space may be an instance in which a socket weld is selected, provided the pressure class is comparatively low and the fluid is not corrosive or for extremely high temperature service.

• Flange Face Type : Flate Face (FF), Raised Face (RF), Ring Type Joint (RTJ)
