10 Types of flanges and their uses

1.WELDING NECK FLANGE:
Weld neck flange is the most generally used flange in method piping. It offers the very best level of joint integrity because of Butt-welded with a pipe. These styles of flanges square measure utilized in high and temperature application. Weld neck flanges square measure large & expensive with relevancy alternative styles of flange.
2.LONG Welded NECK Flanges:
The uses for long weld neck flanges are preponderantly on vessels wherever associate degree extended neck is needed. The uses for long weld neck flanges (LWN) square measure preponderantly on vessels wherever associate degree extended neck is needed. This can be deemed to be a specialty flange because of the sticking neck or hub, that acts as a monotonous extension.
3.SLIP-ON flange:
The slip-on type flanges square measure hooked up by Two fillet welds, within still as outside the flange. The calculated strength from a slip-on flange beneath internal pressure is of the order of simple fraction that of Welding Neck flanges, and their life beneath fatigue is regarding simple fraction that of the latter. Normally, these flanges square measure of cast construction, and the square measure has given the hub. Sometimes, these flanges square measure fictional from plates and don’t seem to be given the hub. The disadvantage of the flange is that a mixture of a flange and elbow or flange and tee isn’t attainable as a result of named fittings haven’t a straight finish that completely fell within the slip-on flange.
4.THREADED flange:
Threaded Flanges also are referred to as screw flange, and it’s having a thread within the flange bore which inserts on the pipe with matching male thread on the pipe. This kind of joint association is Speedy and easy however not appropriate for top presser and temperature applications. Threaded Flanges square measure principally utilized in utility services like air and water.
5.SOCKET WELD flange:
Socket-Weld Flanges encompasses a feminine socket within which pipe is fitted. Fillet welding is completed from outside on the pipe. Generally, it’s utilized in tiny bore piping, and solely appropriate for low and temperature application.

6.LAP JOINT flange:
Lap flange has Two elements, a stub end, and a loose backing flange. Stub finish is butt-welded to the pipe and Backing flange freely yield the pipe. The backing rim is of a distinct material than stub material and usually of the steel to save lots of the price. Lap flange is employed wherever frequent activity is needed, and the house is forced.

7.BLIND flange:
The blind flange may be a blank disc with a bolt hole. These styles of flanges square measure used with associate degree other kinds of the flange to isolate the piping system or to terminate the piping as a finish. Blind flanges also are used as a cover within the vessel.

8.Companion Flanges:
A Companion flange may be a flange that encompasses a hub that’s either socket or threaded that you just would attach to your pipe. A pipe flange threaded internally to receive a pipe length and trained therefore it should be fast to a difference like a flange sometimes: an identical arrangement for coupling Two elements of a shaft

9.Studding outlets Flanges:
Studding outlet flanges (also referred to as outlet flanges, stud pads, or pad flanges) square measure created to order things offered during a type of configurations. The foremost unremarkably used studding outlet flange within the trade is the flat bottom sort. We tend to conjointly supply them during a shell mount, head mount, or alternate radius to line the flanges flush along with your tank or vessel. Simply allow us to grasp the radius and kind of mounting needed, and that we can give these flanges consistent with your application. The smallest amount common outlet flange is the tangential mount, that is offset from a centerline and so lacks symmetry. We offer these outlet flanges consistent with your submitted drawing, and though the mounting detail may be a bit a lot of advances, this usually doesn’t have an effect on the time interval compared to the opposite designs.
