ESSENTIAL OXYCUTTING
We recommend replacing the pipes
- at the first sign of fatigue, wear and tear or damage
- no later than after every 3 years by the user in case of heavy-duty use,
- no later than after every 5 years in all other cases.
We recommend replacing the flame arrester non-returns:
- As soon as flame return occurs
- No later than after three years of use.
Caution:
Follow the rules below if a pipe or valves are replaced:
- Use the spare parts recommended in this documentation.
- The pipes are standardised (colour, composition); they
must be replaced by identical pipes. Gas pipes MAY NOT
BE REPAIRED.
- The fittings must be changed, as they may be damaged
while changing the pipes.
- Fittings must be degreased and cleaned of dust before
assembly: risk of explosion.
- To change a valve on the unit, first take the line off its
support, then take the valve off the line.
- Olive type fittings are screwed on directly.
- Adhesive must be applied on other fittings and valves.
The adhesive must be compatible with oxygen. Risk of
explosion.
- If acetylene is being used, tighten the fittings to
standardised torque according to the diameter (please
contact us). Risk of leaks and fire.
- The pipes in the cable drag chains many not be under
strain, as that could lead to premature wear.
- A leak test (e.g. with 1000 bulles bubble leakage tester)
must be carried out after each repair operation. Risk of
explosion.
Caution:
Whenever a flame arrester non-return is faulty, it must be
replaced. No cutting without anti-return. Risk of explosion and
fire.
