Cutting and fitting
Work on gas installations must only be carried out by skilled personnel.
Before use, the initial part of the coiled BOAGAZ corrugated pipe must always be cleanly cut. Determine the pipe length required. Cut the BOAGAZ corrugated pipe through the lining and stainless steel to length using the BOAGAZ pipe cutter. The cut must be centred between two corrugations. Rotate the cutter in one direction and gradually tighten the roller pressure after each rotation
Overtightening can cause irregular cuts and deformations.
Remove the polyethylene lining with the BOAGAZ stripping knife so that four corrugations are exposed to enable assembly of the fittings. For sizes DN 40 and DN 50 only two corrugations need to be exposed.
The BOAGAZ stripping knife has a sharp blade and the BOAGAZ corrugated piping has sharp edges.
Screw on the fitting. The fitting invariably consists of a union nut, a pair of half-shells (or a pair of half-rings in the case of DN40/DN50) and the counter piece. Separate the half-shells or half-rings at the predetermined breaking point.
Slide the nut over the corrugated pipe. Position the two half-shells (half-rings) so that one corrugation is left exposed at the end of the pipe.
Slide the nut over the half-shells or half-rings and tighten the counter piece of the fitting. Tighten the fitting using an open-ended spanner/wrench until it stops. This action causes the first corrugation inside the fitting to be pressed, creating two seals. After conducting a pressure test, protect the transition from the corrugated pipe to the fitting from corrosion with protective tape or heat shrink tubing.
