PVC Imperial vs PVC Metric — What’s the Difference?

There are two common pressure pipe standards used in the United Kingdom, this is PVC Imperial and PVC Metric. While the outer side of the pipe diameter doesn’t change, the bore changes based on the pressure rating and wall thickness. This is why you need to know the differences, to identify the best choice for your project moving forward.

Functionality and Performance Remains the Same

You will find that both Imperial and Metric provide you with the same functionality and performance due to the fact that the raw material used for both of these products are the same. It is important to know that the difference is not the material itself, but rather the manufacturing standards and size.

There is a Difference When it Comes to the Pipe Size

One of the main differences you will notice is that the PVC Imperial and garden pond pipe fittings is measured in inches, while Metric PVC pressure pipes are measured in millimetres. The metric system is the more recent of the two which measures in metres, centimetres and millimetres and is used extensively throughout Europe. In fact, it is now being used more and more in the United Kingdom too.

The imperial PVC piping measurement is an older system which is used in the United States and in the United Kingdom still in some cases; using yards, feet and inches as units of measurement. The good news is that you can make use of both options in one project as there are interchangeable adaptors available on the market. So you do not have to worry about miss-matching pipework parts!
