Leak Sealing


The PTFE compound injection is relatively  unknown in South Africa but has been successfully implemented worldwide for many years. The valve stem packing injection procedure consists of injections of PTFE compound at the gland area and external stem. If the main bonnet is leaking C.S.T will inject the bonnet area at the same time. Any additional information regarding the procedure including the method statement and risk assessment is available on request. These procedures will increase the longevity and operability of the valve. C.S.T aims to provide full Valve Reconditioning without the need for shutdown, down time or interruption to service.
