Garlock has announced its sealing solution has been used at Rio Tinto Alcan’s Yarwun alumina refinery in Queensland.
After a slurry leak, which had the potential for environmental and safety damage, Rio Tinto Alcan approached Garlock for a suitable sealing solution.
Garlock used its 9000 series Expandable Valve Service Packing (EVSP) with modifications to address specific VOC, VHAP, heat, pressure and chemical issues.
According to the company, due to the need for zero gland leakage, Garlock recommended the use of their standard EVSP modified to incorporate the use of its 1303 FEP die-formed rings at each end of the EVSP.
EVSP is designed to permit selective component compression and controlled radial flow for effective sealing on I.D. and O.D., Garlock said.
Rio Tinto said EVSP has stopped the leaks and delivered zero downtime enabling the plant to run at full capacity until scheduled valve replacement or refurbishment.
