At Kriloha Ltd., we understand that a manhole seal is a critical safety boundary. When a boiler is brought up to full pressure, the gasket must manage both extreme heat and the mechanical “shifting” of the manway plate. The Kriloha Manhole Gasket (SUNWELL GCF-105-IG Style) is our heavy-duty solution for steam-side reliability. As a premier global supplier of high-performance seals, Kriloha Gaskets has mastered the “Wire-in-Fiber” technology to ensure your vessel stays leak-free from start-up to blow-down.
The engineering of the GCF-105-IG style centers on Elastic Compression. We utilize Inconel wire reinforcement because of its superior strength at “red-heat” temperatures. This wire is braided into a high-bulk mineral fiber carrier and then vacuum-impregnated with flexible graphite. The graphite acts as the primary sealing medium, flowing into the microscopic pits of the seat, while the mineral fiber and Inconel provide the “mechanical backbone” that prevents the gasket from being extruded by internal pressure.
Manufacturing these gaskets at Kriloha involves a precision Die-Forming process. We produce these in standard elliptical sizes (e.g., 11″x15″, 12″x16″) as well as custom round or obround shapes. Every gasket is inspected for “Density Consistency” to ensure it doesn’t “thin out” in one spot under load. By choosing Kriloha Ltd., you are investing in a “High-Integrity” seal that reduces the risk of “steam-cuts” on your expensive boiler seats and ensures a fast, safe return to service during every maintenance cycle.
