Manufacturing of nps dn 6 to nps 12 dn 300 pipe is based on fixed outside diameter od.
Pvc pipe diameter sizes in mm.
Below are a series of pvc pipe diagrams and dimension charts to help you find the right sizes or at least get you informed as to the various common sizes available.
Plus 0 2 mm tolerance is allowed on sizes from 16 through 63 plus 0 3 mm on sizes 75 through 125 plus 0 4 mm on sizes 140 through 200 plus 0 5 mm on sizes 225 and 250 and plus 0 6 mm on sizes 280 and 315.
Depending on the structure of the pvc pipe the internal dimensions can vary for example between solid wall pvc pipes and a sandwich constructed pvc pipes.
When it comes to the pvc pipes themselves there are 3 key metrics.
Outer diameter inside diameter and wall diameter as in wall thickness.
To understand this concept you have to learn the way pipes are manufactured.
Pvc pipe sizes referenced in australia and new zealand are mostly in nominal diameter values the reference does not necessarily match up exactly to the outside or inside diameter.
So any increase in wall thickness the inside diameter id of the pipe decrease.
However for the pipe sizes nps 14 and above outside diameter is the same as nps.

Pvc u pipe unplasticized polyvinyl chloride.
Formufit internal fit products such as internal dome caps adjustable elbows internal couplings and other products that fit inside of the pvc pipe will not work with sch 80 pvc due to the smaller internal diameter.
The nominal size is in fact the minimum outside diameter.
Fittings follow this same pattern a 1 fitting has a 1 315 inch opening to accept a 1 inch pipe which actually measures 1 315 inches in diameter.
