Welcome to sainsider.co.za, a comprehensive platform for anything South Africa. In this article, we will be talking about pvc pipe sizes in mm. Kindly stay with us.
Overview
A plastic pipe is a hollow cylinder or a piece of plastic tube. It has a circular cross-section and is commonly used to carry liquids and gases (fluids), slurries, powders, and large quantities of minute particles.
Hollow pipes can also be employed in structural applications because they are significantly stiffer per unit weight than solid sections.
Drinking water, waste water, chemicals, heating and cooling fluids, foodstuffs, ultra-pure liquids, slurries, gases, compressed air, irrigation, plastic pressure pipe systems, and vacuum system applications are all transported using plastic pipework.
About PVC Pipes Size
Plumbing sizes and names in pools and spas can be perplexing, as plumbing sizes are referred to as “Nominal” sizes. The term “nominal” refers to “by name only” and does not reflect the actual dimensions of the pipe. This is due to the fact that pipes were previously measured by their internal diameter, which was measured where they slipped over a fitting. The thickness of the wall became more important throughout time, and the name stuck or evolved.
The charts below have names over the actual dimensions. We exclusively utilize “Pressure Pipe” in pool and spa water plumbing.

Useful Measuring Information
- Measurements are always taken from the Outside Diameter (OD) of the Pipe OR the Inside Diameter (ID) of a fitting’s Socket.
- Because fitting thickness varies greatly, the OD of a fitting or socket is absolutely irrelevant.
