Cutting pipes

Check the outer diameter. Before cutting, use a circumference tape to check that the OD measured is less than OD + 1 mm.

DN ≤ 300: preferably, cut at a distance of less than 4 m from the pipe spigot.
DN > 300: preferably, cut the calibrated pipes specified in the order and identified by metal grey painted rings on the socket edges.

Mark

Mark the cutting plane perpendicular to the pipe axis.

Cut

  • For DN 60 to 700

Use a cut off machine, for example.

  • For DN 800 to 2000

Use a pneumatic cross cut saw (e.g. FEIN) which, with an adaptation, can produce the chamfer at the same time.

Fettle or chamfer

For EXPRESS mechanical joints, collar, fettle the cut edges with an angle grinder.
For STANDARD, STANDARD Vi, UNIVERSAL, etc. automatic joints redo the chamfer with an angle grinder to avoid damaging the joint.

Redo the coating

Recoat the edge exposed by the cut and the chamfer.

For the traditional black coating:
- ENDOLAC 245-30 (1 kg: Ref. 518134; 5 kg: Ref 158131)

For NATURAL coating:
- EUROKOTE 438 (1 kg: Ref. 158255)
- AQUACOAT (0.75 kg : Ref. 240991)
