Closure door protection.
Closure door protection.
Closure locks from Netherlocks Safety Systems eliminate the danger of improper operation of pigging system valves by ensuring correct operational procedures are followed.
Pigging systems are used to insert a pipeline inspection gauge into a live system transporting gas or liquid media to perform various maintenance operations. Dealing with such high-pressure levels, pigging operations require a precise sequence of valve operations. The lock protects against improper operation of the closure door, where common accidents include: opening the closure door while pressure still remains inside the vessel; opening the main process valve while the closure door is not fully closed and opening the closure door while a high concentration level of toxins still remains inside the vessel.
A series of keys lock into place and can’t be removed out of sequence. This guarantees workers always follow the correct valve operation procedure.
Netherlocks is a Houston-based supplier of safety and valve control systems for major industrial operations.
