A PPR split flange fits around an installed PPR stub to make a bolted joint.
It opens in two halves. Therefore, you can fit or replace it without cutting the pipe.
What is a PPR split flange?
A PPR flange joins a PPR pipe to flanged pumps, valves and tanks with bolts. A PPR stub fuses onto the pipe, and a flange ring clamps it to the mating flange.
A split flange opens in two halves, so it can be fitted after the stub is welded. A one piece flange is a single ring that slides on before welding.
