Threaded connections and fittings are points that require special attention in natural gas installations, especially after disassembly or maintenance.
Common causes
Incorrect assembly, unsuitable sealing material, damaged threads, or excessive mechanical stress can lead to micro-leaks.
Post-work inspection
Every connection that has been disconnected and reassembled must be tested before returning to normal operation.
Foaming solution
For accessible areas, an approved foaming liquid is used. Continuous bubble formation is an indication of a leak.
Electronic detector
For smaller leaks or hard-to-reach locations, a suitable gas detector is used.
After repair
The connection is re-tested and the restoration is documented.
