They are commonly used in heat exchangers, reactors, and pressurized boilers, as well as in chemical, petrochemical, and refinery plants. They offer high resistance to elevated temperatures.
Especially in oil refineries, power plants, natural gas and oil pipelines, fertilizer, and paper factories, they serve as sealing elements in areas with intense pressure and temperature.
Depending on the application, they are manufactured using different winding and filler materials such as graphite, PTFE, mica, and fiber.
