COMPOSITE LEAK REPAIR – NATURAL GAS FLANGE LEAK Case Study
Composite Leak Repair
Details:
More
Leak area: 8inch Valve flange
System Medium: Natural Gas
System Pressure: 2.5Bar
Valve body: Cast Iron
Flange Material: Carbon Steel
Leak Conditions:
A natural gas leak was found on an 8 inch valve’s flange; the system pressure was 2.5 bar. The leakage was detected at 2200hrs. Due to the high risk of ignition and safety for everyone, immediate containment was required.
Traditional Leak Containment Versus Composite Leak Repair due to the medium of the leak, any solution with hot work was not permitted. With the irregular valve body shape, it added another level of difficulty to the repair method. By Using Traditional Leak Containment would require longer lead time to fabricate and install, concurrently the system would be required to shut down. Under this circumstances, resolving the leak immediately was our priority. Therefore, Composite repair methodology was adopted in this scenario. Composite Repair allowed the repair to start immediately and with the added flexibility to seal leak on odd-shaped object.
