Cutting/Flaring the pipes

E-10

Connect the pipe within 50m and cutting pieces will not be gone

into the pipe as being clean to pipe section.

Make sure that you have the required tools available (pipe cutter, reamer,

flaring tool and pipe holder).

If you wish to shorten the pipes, cut it with a pipe cutter, taking care to

ensure that the cut edge remains at a 90° angle with the side of the pipe.

Refer to the illustrations below for examples of edges cut correctly and

incorrectly.

To prevent any gas from leaking out, remove all burrs at the cut edge of the

pipe, using a reamer.

Slide a flare nut on to the pipe and modify the flare.
