Solution & Implementation
Furmanite applied its tried and tested leak-sealing technology to the new application, producing a bespoke solution. This involved removal of all the existing fasteners and bolts on both ends of the drier, installation of specialist ring adaptors under the new bolts, and injection of the peripheral joint areas with a specialist sealing compound. The compound was designed to the tolerances of the drier, ensuring that it would not react to the change in operating temperature from 8 bar steam to ambient when shutdown.
The work, undertaken during a scheduled outage with engineers under tight time limits to complete the job, included changing out and injecting as many as 600 bolts on the 12 foot cylinder. It was completed, working night and day shifts, in just a 4 day period.
