Spiral-wound gaskets
Exhibitor
HST Hamburg Sealing Technologies GmbH
Spiral-wound gaskets are high-performance semi-metallic sealing components widely used in industrial piping systems, pressure vessels, heat exchangers, and valves. These gaskets are super springy and highly resilient by ensuring tremendous flange tightness with leak free flange assembly joint even under high pressure operations with wide pressure fluctuations and with severe thermo cyclic temperature variation.
We supply multiple gasket styles including Style R, Style IR, and Style CGI spiral-wound gaskets, available with inner and outer rings. These designs help improve flange alignment, prevent blowouts, and maintain sealing stability under high-pressure conditions.
All products comply with major international standards such as ASME, DIN and EN ensuring durability, corrosion resistance, and extended service life in demanding industrial environments.
