In chemical, petrochemical plants and refineries volatile organic vapours and gaseous products losses mainly originate from valve glands. Deterioration of packing material over a period of time requires regular monitoring, gland adjustment and eventual replacing of the gland packing before the gland has completely “bottomed out”.

The LDAR programme is essential for an effective valve gland replacement management system. it identifies those leaking valves in need of gland repacking and can also prevent the unnecessary maintenance to valve (glands) that are still in good condition.

As an extension to our LDAR service, Enserve Environmental Services offers an in-situ Valve Gland Repacking service. This completes the repair portion of the overall LDAR programme by ensuring that unnecessary process leaks are reduced to a minimum.
