What are Flanges?
Flanges are forged rings that are available in numerous diverse shapes and sizes. They are used in an extensive range of industries across the world to connect valves, pipes, and other equipment in the piping system.Â
Two separate machinery parts are combined by forged flanges and you can get them from forged flanges manufacturer Rajkot.
Normally, flanges are welded or threaded, and by bolting them with gaskets, two flanges are connected to impart a seal that gives straightforward access to the piping system.Â
Different types of flanges are available for use in a piping system such as weld neck flanges, slip-on flanges, socket weld flanges, blind flanges, etc.
With so many diversities and specifications, you may find it difficult at first to identify which one is appropriate for you.Â
Besides, there are many forged fittings manufacturing processes to make a tee, elbow, reducers, and other pipe fittings.
Here is a list of the most common and popular types of flanges used in the piping system.
Types of Flanges
- Weld Neck Flanges:Â Named for their protruding necks, weld neck flanges are also called high-neck flanges.Â
- The bulky weld neck flange has a neck, through which the pipe tension can be properly transferred.Â
- Also, it helps decrease the pressure built up at the flange bottom. It is well-suited for pipelines that function at high or low temperatures and endure high pressure.
- Slip-on Flanges:Â The slip-on flange is a ring located at the end of the pipe. As the name implies, these flanges slip onto the pipe and are called slip-on flanges.Â
- The flange face increases from the pipe’s end by an adequate distance to employ a welded bead to the inner diameter.Â
- They are inexpensive, popular, and best applied in low-pressure, low-temperature systems.
- Socket Weld Flanges:Â The socket weld flanges are attached to the outside simply by a fillet weld. It is frequently not suitable for critical services.Â
- These are normally used on small, high-pressure pipes such as hydraulic pipes. Socket weld flanges can accept pipe into the socket to make the fitting.Â
- They are commonly brought into play as a substitute for weld neck flanges when space is limited.
- Blind Flanges:Â The manufacture of blind flanges occurs without a bore and is employed to shut off the ends of valves, pressure vessel openings, and pipes.Â
- They are appropriate for high-pressure systems, in addition to testing the gas or liquid flow through a pipe.
- Threaded Flanges:Â Threaded flanges are comparable in design to slip-on flanges but they have a tapered thread, implying they can be fastened to pipes without welding.Â
- This type of flange has taper pipe threads in its bore matching ASME B1.20.1 and is useful in piping systems. Similar to slip-on flanges, they are best applied in low-pressure, low-temperature settings
- Lap Joint Flanges:Â Lap joint flanges are beneficial with stub ends when expensive material is used to make the pipe, for example, you can add a carbon steel flange to the stainless-steel pipe usage because the flanges do not touch the substance in the pipe.
ConclusionÂ
It is hoped that you can figure out from the above different types of flanges and it should help you recognize the crucial things before buying flanges.
