Types of Flanges
The most used flange types are Welding Neck, Slip On, Socket Weld, Lap Joint, Threaded, and Blind flange. We usually consider two main families of flanges, the standard flanges, and the special ones.
Flanges are used to connect pipes, valves, pumps, and other equipment in various industrial applications. There are several types of flanges available, including:
here’s a table presenting common flange types along with their descriptions:
| Flange Type | Description |
|---|---|
| Weld Neck Flange (WN) | – Has a long tapered hub that provides reinforcement to the connection. |
| – Ideal for high-pressure and high-temperature applications. | |
| – Commonly used in the petrochemical, oil and gas, and power generation industries. | |
| Slip-On Flange (SO) | – Has a bore slightly larger than the outside diameter of the pipe. |
| – Easy to install and cost-effective. | |
| – Suitable for low-pressure and non-critical applications. | |
| Blind Flange (BL) | – A solid plate used to close the end of a pipe or vessel. |
| – Often used to isolate sections of a pipeline for maintenance or inspection. | |
| – Commonly used in the oil and gas industry. | |
| Socket Weld Flange (SW) | – Has a socket or recess that accepts the pipe end. |
| – Ideal for small-diameter and high-pressure applications. | |
| – Commonly used in petrochemical and chemical industries. | |
| Threaded Flange (TH) | – Has threads on the inner bore and is screwed onto the pipe. |
| – Suitable for low-pressure and non-critical applications. | |
| – Commonly used in plumbing and small-diameter piping systems. | |
| Lap Joint Flange (LJ) | – Consists of two parts: a stub end and a backing flange. |
| – Allows for easy alignment of bolt holes and is used in systems requiring frequent dismantling. | |
| Orifice Flange (OF) | – Specifically designed for flow measurement or control. |
| – Has a smaller bore opening with a set of bolt holes for mounting an orifice plate. | |
| Expander Flange (EX) | – Used to increase the pipe size gradually. |
| – Often used in pipeline expansions and transitions. | |
| Reducing Flange (RF) | – Connects pipes of different sizes. |
| – Has one end with a larger bore and the other with a smaller bore. | |
| Anchor Flange (AF) | – Used to anchor piping systems to a structure. |
| – Provides support and prevents movement. | |
| Swivel Ring Flange (SRF) | – Allows rotational movement of a flanged connection. |
| – Used in systems where flexibility is required. | |
| Groove and Tongue Flange | – Has a groove on one flange face and a matching tongue on the other. |
| – Provides additional alignment and sealing in high-pressure applications. | |
| Ring Type Joint Flange (RTJ) | – Uses a metal ring gasket for sealing. |
| – Common in high-pressure and high-temperature applications. |
This table provides a clear overview of common flange types and their respective characteristics.
These are just a few of the most common types of flanges. There are many other specialized flanges available for specific applications, including high-pressure and high-temperature applications. It’s important to select the right type of flange for your specific needs to ensure a safe and reliable connection.
