Long Weld neck flange dimensions are covered in ASME B16.5 – which covers Pipe Flanges and Flanged Fittings for size NPS ½” to 24” for above NPS 26” to 60” it should be as per ASME B16.47.

In this article, I have tried to cover some of the special flanges such as Orifice flange, long weld neck flange, reducing and expanding flanges and flange olet that used in piping and equipment.Special flanges are not as common as regular flanges.
The flange is second most used joining method after welding. Flanges are used when joints need dismantling.
Flanges are used to join two joints of pipe.
Expander Flange is a Welding Neck pipe flange where the nominal size of the non-flanged end is larger than the nominal size of the flanged end.
As already described before, the most used flange types acc. to ASME B16.5 are: Welding Neck flange, Slip On flange, Socket Weld flange, Lap Joint flange, Threaded flange and Blind flange.
Reducing flanges are designed for when there is a change in the pipe size.
The American National Standards Institute (ANSI) calls for the use of an ANSI flange to be used on specific applications. The ANSI flange is a three-part flange consisting of one flat flange, one flange machined to take a rubber O-ring…
Pipe flanges are method of connecting pipes, valves, pumps and other equipment to form a piping system.
