Field Problem / Customer Need
Inlet points in HRSG boilers are among the most challenging expansion points due to large movement requirements. Especially at GT exhaust temperatures, large movements occur in a limited cross-section in the floor and side wall regions of the front modules. This makes a reliable and durable sealing solution critical.
BundleTec Innovation and Engineering Solution
The challenges in replacing traditional metal expansion joints and leaking packing seals or mechanical gaskets increase the need for regular maintenance and have negative effects on the containment and surrounding equipment. This makes them an expensive and unreliable solution.
At BundleTec, we have developed innovative fabric sealing solutions compatible with existing systems to address these issues. These solutions allow for regional patching, repair, and component replacement, thereby minimizing downtime or outages.
Engineered fabric structures maintain their shape without creasing or folding throughout all movements, offering excellent performance in high-cycle operations. Multi-layered structures and high-temperature resistant membranes ensure gas tightness and provide protection against stress.
