Unlike flexible graphite cut gaskets, the compression of the ORIGRAF® die-formed seal is limited by a mechanical stop: groove or inner andor outer ring. In the case of assemblies subject to extreme pressure andor temperature this design prevents application of an excessive seating stress on the seal during transients.

Sealing Concept A large variety of the most difficult sealing problems can be solved using VITAFLEX® spiral wound gaskets. Although its basic fundamental principle has little changed since its creation, production techniques and materials used developed over the last 30 years have enabled our gaskets to be adapted to a much broader range of applications. Research and Development Extensive research and development programs on the VITAFLEX® spiral-wound gasket have enabled the essential parameters relating to the performance of the gasket to be mastered. This is particularly the case for the profile of the metal strip, choice of material, filler quality, gasket compactness, compressive force and seating pressure. We can offer optimized gaskets perfectly adapted to our customers specific requirements including operating conditions, sealing, dimensioning of assemblies and safety level. Operating principle The VITAFLEX®; spiral-wound gasket operates by the axial compression of the winding, which results in the plastic deformation of the filler material on the sealing faces. The metal strip optimized profile provides elastic recovery, a vital function in order to maintain sealing on a bolted assembly. Description The winding, or the active part of the gasket, consists of an alternating combination of formed metal strip and soft filler material wound together. The soft filler material is selected to suit the medium which is to be sealed off (pressure, temperature, fluid). Several consecutive turns of the metal strip are welded together at the beginning and end of the winding in order to maintain the tension. Main Applications Chemical & Petrochemical Industry: catalytic synthesis, heat exchangers, vessel gaskets, piping, valves, and storage Nuclear Industry: cooling systems, valves, manholes, handholes, and heat exchanger with or without partition walls General Industry: high and low pressure steam systems, autoclaves, heat exchangers, heat transfer fluids, high pressure, hydraulic piping, valves, compressors and pumps
