Flange Coupling Adaptor: Working Principle and Uses

Plumbing tasks revolve around constructing efficient and reliable systems for transporting water or fluids. Whether you are talking about a household plumbing repair or a commercial-level tank fix, connecting different components requires some effort.

A coupler is a common term in the piping and plumbing world. These are metallic sockets that help you connect two pipes. A flange adaptor falls under the class of plumbing couplers.

These adaptors connect two or more pipes, ensuring enough space for expansion and contraction. A flange adaptor looks like a heavy pulley with adjustable screws to hold the pipes in place. Let’s see how a flange adaptor works and where you can use it.

How Does A Flange Coupling Adaptor Work?

Knowing about the structure of a flange coupling adaptor will help you understand a lot about its work. Let’s quickly see what back-stage events fuel the working of a flange adaptor.

The two discs of the adaptor come with locking screws to hold the pipes. The pipe with similar out-shaped flanged corners is fitted with the flange adaptor, and the locking screws are tightened. Similarly, another tube on the other side of the coupler is installed.

It is important to note that flange couplers are slightly larger than the periphery’s size. It ensures the joint can remain intact even when pipes go through contraction or expansion.

Flange adaptors are used where the connecting components have different flanges. For instance, one element is flanged, and the other is non-flanged. There are various flange adaptors available. However, the correct buy is only possible when you know what type of components you want to connect.

Applications Of Flange Couplers

Flange couplers or adaptors are more than just a consumer-level thing. They are used in various industrial projects. Some standard applications of flange couplers include valve and pipe fittings, backflow prevention mechanisms, inline fitting, etc.

How Are Flange Adaptors Different from Coupling?

The term flange is of utmost importance when dealing with industrial plumbing. A flange is a protruding collar with holes visible on large pipes. At the same time, a flange adaptor is a device that fits on these flanges to connect the line to another component.

Flange adaptors can also have two different types of flanges depending on the periphery in which you want to install them.

Kinds of Flange Adaptors Available

Flange adaptors are available in multiple versions. However, manufacturers also make custom flange adaptors for installation with their equipment. Purchasing the same pipes and adaptors from the same company minimizes the complexity of plumbing.

The flange adaptors are made from pure steel and are usually classified into two classes based on their rubber rings, FADS-S and FADS-K. The FADS-S contains an S-shaped rubber ring, while the FADS-K contains a K-shaped one.

Another category of flange adaptors made from ductile iron includes FADS-DT and FADS-DT flange adaptors. The former connects the pipes via face-to-face joining, and the latter use connecting bolts to connect the lines or pipes.

Final Verdict

Flange adaptors are couplers used for joining various plumbing components on the industrial level. These adaptors can join flanged, non-flanged, and differently flanged pipes together. However, you must analyze the nature of the adjoining periphery before picking a flange adaptor.

The article discusses some common factors like the working principle, applications, and types of flange adaptors. However, using them on an industrial level requires more field knowledge and critical component analysis.
