Spiral wound steel gaskets are industrial sealing elements that provide superior sealing performance in high-pressure, high-temperature, and demanding operating environments. Their steel spiral winding structure — combined with elastomer or graphite filler — delivers exceptional strength, flexibility, and re-seating capability.
Flowland spiral wound gaskets provide long-lasting, reliable sealing at flange connections, pipelines, pressure vessels, valves, and other critical sealing points across petrochemical, energy, and marine installations.

Frequently Asked Questions
A spiral wound steel gasket is an industrial sealing element made from alternating layers of stainless steel strip and filler material (elastomer or graphite) wound into a spiral. This construction provides high mechanical strength, flexibility, and reliable sealing under extreme pressure and temperature conditions.
They are used in flange connections, high-pressure pipelines, steam and heat systems, valve and pump bodies, pressure vessels, and any application requiring robust sealing in oil, chemical, energy, and marine environments.
Graphite filler provides excellent chemical resistance, high-temperature stability, and self-lubricating properties. It enhances the gasket's ability to conform to flange surface irregularities and maintain a reliable seal across a wide temperature range.
AISI 304 and AISI 316 stainless steels offer corrosion resistance, mechanical strength, and long service life in aggressive environments. AISI 316 provides additional resistance to chloride and acidic conditions, making it the preferred choice for marine and chemical applications.
Flowland spiral wound steel gaskets are rated up to 250 Bar pressure and can operate across a temperature range of -200°C to +540°C depending on the model and filler material selected. Contact Flowland to confirm the correct specification for your application.
