Spiratem 123 Spiral wound gaskets

 METALLIC / SEMI METALLICMETALLIC / SEMI METALLICSPIRAL WOUND GASKETS OF SPIRATEM

The sealing element of the spiral wound gasket consists ofThe sealing element of the spiral wound gasket consists ofa v-shaped metal strip spirallywound in combination with a softsealing material filler. The metal strip provides outstandingresilience, while the flexible sealing filler guarantees excellentsealing. Due to the combination of materials the spiral woundgasket is suitable for sealing under severally fluctuating temperatureand pressure conditions. Depending on the applicationthe spiral wound gasket can be specified with outer and/orinner rings.• spiral wound gaskets are suitable for use across a wide pressure range, and therefore is general - purpose gasket universally applicable• spiral wound gaskets can be used to seal fluid pressure up to 250 bar and cryogenic temperature as low as -200 °Cand high temperature up to +550 °C / +1100 °C (on special request)• due to its sturdy design the spiral wound gasket is simple to install without causing damage (although extra care should be taken duringtransportation and installation of large diameter gaskets without guide rings)• outer guide rings serves to seat the spiral element centrally onto flange faces and prevent blow-out• thanks to the combination of different winding materials and metals, gaskets can be tailor made to a wide variety of operating conditions• due to its non-adhesive character the gasket is easy to remove after service• gaskets does not cause any damage to the flange faces.
