The original frame design was insufficient for long-term base loads or short-term cycling. This low quality installation led to the inevitable breakdown of the expansion joint and adjacent structures.
DEKOMTE Fabric Expansion Joints offer greater flexibility whilst maintaining longevity and reliability. With the joint delivered complete with internal insulation, the installation process was quick and efficient, keeping the outage duration to a minimum.
Creating a hot casing frame connection for the inlet, whilst maintaining the cold casing outlet frame, utilised the best arrangement for a high cycling available solution, whilst giving making the optimum transition and integration for the exhaust duct. DEKOMTE fabric and steel frame design is much better suited to the varying starts, while remaining gas tight and cost-effective.
