Thorough Explanation of AES Woven Fabric Gasket with 800℃ Heat Resistance, Safety, and Flexibility

A thorough explanation of why No. 1420-ST is evaluated as a particularly balanced option in the 800°C class high-temperature seals!

"I want to use a safer RCF-free material for the boiler manhole gasket." "The exhaust duct reaches high temperatures close to 800°C, but there is distortion on the flange surface, making it impossible to seal with a sheet gasket." "For large-diameter high-temperature flanges, the gasket is too soft and loses its shape during installation." Power plants, incinerators, various industrial furnaces, and exhaust systems of diesel engines are subjected to harsh high-temperature environments that can reach 800°C. The gaskets used in these applications must not only have excellent heat resistance but also ensure material safety to protect the workers, as well as flexibility to conform to the distorted flange surfaces typical of high-temperature equipment. However, at the same time, especially for large diameters, ease of handling during installation is also an important factor that cannot be overlooked. *For more details on the column, please refer to the related link.
