Once you understand what a pipe fitting is, you can appreciate that there’s a need for different types of pipe fitting – to fit different types of pipes, used for different jobs.
Pipe fittings are the parts that connect pipe sections either together or to other components in a variety of configurations.
According to A.M.J. Metal Roofing in Brisbane:
“The type of pipe fitting needed for a job will largely be determined by:
- the connection type required
- the job that the pipe fitting needs to do”
You’ll hear people talking about pipes, tubes and hoses. Although all of these describe exactly what you’re likely to be visualizing – long hollow cylinders – tubes and pipes are actually far more similar than hoses.
- Hoses are usually more flexible and made up of many layers of different materials, dependent upon their usage.
- Pipes and their fittings are defined with nominal rather than exact dimensions. Pipes are primarily used to transport fluids.
- Tubes have actual and rated dimensions that are the same. Tubes can be used to transport fluids however they can also be used structurally.
Types of Pipe Fittings:
There are different way to connect pipes and pipe fittings and the best option will depend on how the pipe is being used and what you need to be achieved.
Some of the most popular type of pipe fittings include:
1. Compression Fittings
These connect pipes using compression on a gasket, ring or ferrule. It’s made by tightening a nut onto the fitting over the piping and ferrule. This compresses and secures the pipe inside.
The advantage of these fittings (usually used for metal on metal connections) is that they generally do not require tools to assemble them and are therefore quick and simple to work with. They do not however have the capacity to withstand very high pressures.
2. Bite Type Fittings
Another type of compressive fitting, these have a sharpened ferrule which bites the pipe when it’s compressed – therefore providing a seal. They can provide a strong connection which can withstand higher pressure connections than standard compression fittings.
3. Mechanical Grip Fittings
If you need a strong fitting that will provide good resistance to mechanical vibrations and withstand being reassembled without damage, you may want to try using mechanical grip fittings.
These are made up of two ferrules – the back ferrule grips the pipe whilst also pressing against the front ferrule. This spring loads the front ferrule and a seal is created between the piping and fitting body.
4. Flare Fittings
This type of fitting has a specially designed flared or coned end which the pipe is installed into using special tools. This provides a deep seal meaning that flare fittings are able to withstand high pressures.
5. Threaded Fittings
An intricate yet highly effective design threaded fittings have screw threads which are built in grooves that lie on either their inner or outdoor services.
These grooves are designed to accept piping with matching threads.
The threads can be either:
- straight threads (these provide a connection but no seal)
- tapered threads (these provide a tight seal to withstand gases or fluids under pressure)
- dry fit threads (these are exact threads that do not require any additional sealant)
The Right Choice for You
There are a vast range of pipe fittings available and connections are becoming ever more effective whilst remaining simple to install.
Always seek expert advice to find the right choice for you and consider the specific application of the pipe that you need to connect before deciding on the best fittings.
