Before understanding uses, functions and things like that in detail, we must get a brief understanding of the product.
When we have to join two thin-walled pipes or tubes together, of course, something is needed to join them. Something really strong and reliable to keep them and walled pipes together is needed. For this, there is nothing better than Compression Coupling Copper.
Structure of Compression Coupling Copper
If we talk about small-sized compression coupling then it has two parts. Let us how the structure of the coupling is designed for maximum support. The outer part is called the outer compression nut and then there is the inner compression ring. The inner part is called the ferrule. This may also be referred to as olive, in some parts of the globe. The inner part which is also called the ferrule is made up of brass, steel or copper. Copper is most preferable as there are many advantages of Compression Coupling Copper. Now, the ferrule may be of different shapes and materials. However, most commonly you will find that ring is the most common shape. Copper ferrule or the olive has a barrel shape. This barrel shape is quite a help as it prevents wrong fitting and makes sure that the ferrule/olive is oriented properly. However, this has to be taken care of when we are talking about Hydraulic and pressure applications.
Large-Sized Compression Coupling
When we talk about large-sized compression coupling copper then a single nut is not going to be enough to compress the ferrule. What is needed is a flange with a ring of bolts. Here the technician has to take care of the fact that bolts are evenly tightened. Let us find out more about this topic. Read ahead:
Types of Compression fittings
Now, there are two different types of Compression fittings. Let us take a look at those. There are two major categories here.
- Standard Type (Non-manipulative)
- Flare type (Manipulative)
The first and foremost feature of the standard type is that there is no need for any modification in the tubing.
Now with flare type, it is quite the opposite. A special tool is to be used for the modification that is made in the tubing.
There are different areas where these two types of compression fitting are used:
- Standard fittings are used for hydraulic and compressed air connections
- On the other hand, flare types are used for high and gas pressure lines.
One must also know that there is one more type of compression fitting and it is called push-in compression fitting. These are best fitted over the tube’s end and this is best done using a grip ring. This helps in holding the side of the tube.
Advantages and Disadvantages
There are several advantages and disadvantages of compression coupling copper. We shall briefly go over it:
Advantages
The very first advantage of this is that there is no need for soldering. This makes it easy and quick to use. One does not have to be a skilled person to operate it and there is no need for any special tool to operate.
If you are using compression coupling in the machine that requires partial removal for maintenance then this one will be good and well suited to enable hassle-free maintenance.
Disadvantages
If we compare it to soldered fittings then the level of robustness is lesser in compression fitting compared to soldered fittings. Also when the fitting is subjected to flexing and bending, this may not be a great choice to go for. Compression coupling copper is sensitive to stresses. In the same place when we look at the soldered fitting, we shall see that the flexibility is quite high, comparatively.
In the next blog, we shall find out more about Linear Bearing.
So, these were some of the things that we must know when we deal with compression couplings. Now, these things may get highly technical but this blog aims to make laymen understand the basics of it. Hope that the blog has been successful in that. If you have any questions, do drop a mail to Thompson Couplings. info@thompsoncouplings.com
