Located at the aft end of the exhaust manifold, leaf seals are overlapping sheets of thin-gauge Inconel and the only seal between the exhaust tunnel and the A042 transition diffuser duct. While not gas tight, in time, the combined high temperatures and the cycling of the gas turbine leads to leaks in the OEM seal which offer little flexibility and restrictive movement. When the leaf seals deteriorate, facility personnel and nearby equipment may become vulnerable to high-temperature exhaust gases, posing risks of injury and potential equipment damage.

PSIG’s Flex Seal Upgrade combines advanced design, materials, insulation, and fabrication to address the leaf seal challenges while providing a longer life cycle. Our team leverages decades of experience in turbine exhaust fabric expansion joint design, development, and repair to deliver the most reliable Flex Seal Upgrade solution available on the market today.
