Semimemetro seals made by spiral coil of a V-shaped metal strip together with an inorganic filler ma terial. The metallic material can be made of stainless steel (304L, 316L, 316Ti, 317L, 347, Duplex, …) to special alloys: AL6XN, Hastelloy C22, Hastelloy C276, Titanium, Tantal um, …). The filling material is usually: Graphite, PTFE or Mi ca.Se can be manufactured according to specific standards (ASME B16.20, UNE EN 1514-2) or according to the specific design of the customer and different configurations:S/A: with out rings. IR: with inner retaining ring. CR: with external centering ring CRIR: with inner and outer ring.
