A PPR one piece flange gives a solid ring for bolted joints between PPR pipe and equipment.
Slide it onto the pipe before welding the stub. In addition, it suits new installations.
What is a PPR one piece 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.
