Copper tubes
Views: 1710
Copper tubes are assembled using specific gas couplings.
These couplings are welded on the pipe lines by silver brazing or braze welding using borax- coated brass.
Copper tubes must meet NF A 53-1 00 standards, IGU and AFG B 524-1 specifications. The couplings must meet IGU and AFG B 524-2 specifications.
The solders must meet IGU and AFG B 524-6 specifications.
This equipment, largely used in gas distribution installations, comes in two types:
Cold-rolled copper tube: delivered in bars of 3, 4 or 5 m “rigid tube”
Annealed copper tube: delivered in rings of various lengths according to diameter “malleable tube”
