On Tuesday March 7, 2023, UreaKnowHow.com presents “A Blocked Leak Detection System, What to do ?”
The presence of a reliable leak detection system in lined high pressure urea equipment is a must. Only a state-of-the-art active leak detection system provide sufficient safety and reliability.
Leak detection systems should be checked before installation, after a shut-down and during operation to ensure communication between the holes of each liner compartment. A leak detection system should be always in operation especially during stops, start-ups and shutdowns to minimize the risks for blockages. A vacuum leak detection system is the only leak detection system that allows a reliable leak detection in all these operating modes.
Once a leak detection system is blocked, restoring communication will be difficult and depends strongly on the location of the blockage. In case of a liner leak, the risk for any permanent blockage behind the liner is realistic. In case of a blockage behind the loose liner, only a vacuum leak detection system assures a maximum liner area under direct and reliable detection.
We strongly advise never to flush behind the liner with water, condensate, or steam.
