The pressure pipe fits inside the 'main run' ends. The 'main run' is equal in size, the branch (also known as centre) is same dimension or smaller. This is often used in irrigation to allow for risers and spinkler heads.
Pressure PVC pipes and fittings are made from PVC-U. The pipe is rigid and comes in 6mt lengths.
The pipe is joined with it's mating fitting using solvent cement. See installation guide for PVC-U. The jointing system in known as solvent cement joints(SCJ).
