Overview
This industrial-grade spiral wound gasket is engineered for high-integrity sealing in demanding piping and pressure vessel applications. Designed to meet the rigorous HG/T standard, it provides a reliable, leak-tight seal for flange connections operating under significant pressure and thermal stress. The gasket features a robust construction with alternating layers of metal and filler, creating a resilient seal that accommodates flange rotation and surface imperfections. It is suitable for sealing a wide range of aggressive media in critical process environments.
