      Product Description

      Lens Ring Type Joint Gaskets - Style LRTJ 305

      A Lens Ring Type Joint Gasket is usually a line contact seal for use in high pressure piping devices as well as in pressure vessel heads. This lens cross section is often a spherical gasket surface area and requires specific machining on the flanges. In obtaining lens gaskets, complete drawings and product technical specs need to be supplied.

      With certain applications, the specifications of the high integrity metallic seal has usually lead to the selection of the actual lens ring type joint gasket, rather than much more generally known ring type joint alternative. The lens ring type joint gasket is covered solely by the DIN 2696 specifications. Having said that, ASME B16.5 and other flange styles might be customized to just accept the lens ring type joint gasket. The lens ring type joint gasket provides for a metallic gasket design incorporating spherical seating faces made to accommodate specifically mating flange recesses, offering the end user with a great sincerity, high-pressure and temperatures metallic to metal seal. Like all metal gaskets, the Lens Ring material ought to be given much softer when compared to the flange material, thereby assuring utilized compressive stress causes the elastic or plastic-type deformation of the lens ring type joint gasket and not to the particular flange sealing facial area. The circulation of high compressive loads brings about the spread out from the gasket facings, making sure over stressing of the gasket is stopped.

      In accordance with DIN 2696 common components are restricted to a range of specified carbon steels and stainless levels, even though alternative grades are offered upon require. Ningbo Kaxite needs a detailed drawing be supplied when ordering non regular lens ring type joint gasket.
