The valves were Repacked using Geegraf BGPR which is a high pressure high temperature braided inconel reinforced valve gland packing. In 13 years of valve repacking at the Conoco Phillips site Gee Graphite have never been called back to repack a valve gland failure after a plant shutdown.

In April May and June of 2014 Gee Graphite completed the unpacking and repacking of 132 valves on the No 7 Stabiliser, the majority of the valves which were repacked were on cold and hot oil duties. The repacking of the valves were carried out using the High Pressure Water Jet Unpacking Machine with two Technicians in attendance, the valves were repacked using Geegraf BGPR. The Valve repacking was completed in the specified time schedule as requested by Conoco Phillips and consisted of various size valves ranging from ½” valves up to 24” valves.

The first plant which was in February, valve repacking was carried out on No 1 Boiler where Gee Graphite repacked 100 valves using Geegraf BGPR with the use of the Unpacking Machine and two Technicians. The valves repacked were on high pressure steam and saturated steam applications.
