ASME B16.21 Flat Sealing Klinger Non-Asbestos Asbestos Free Gasket

Company Profile Non-asbestos gasket is made from special non-asbestos heat-resisting fiber, natural rubber compound heating and compression molding. It eliminates asbestos rubber sheet essentially and thoroughly. The maximum dimension reach 2700 x 2700mm.Certifications Non-Asbestos Fibre materials are so-called because they fill the gap in the range of gasket materials previously occupied by asbestos. Asbestos, although now known to be a dangerous material, had excellent heat resistance properties, which is why it was utilised so widely in high temperature applications. When asbestos was outlawed, replacement materials were needed; and so these asbestos-free, or non-asbestos, materials were developed to perform the same function, but without the corresponding danger to human health. These materials are now commonly comprised of aramid fibre (Kevlar) and non-organic fibres, which are in turn blended with different polymers to meet different applications: most commonly nitrile rubber, for fuel and oil resistance. These materials can also be graphite coated for non-stick and steam resistance, mixed with PTFE for excellent chemical resistance, or with EPDM for potable water applications. Common Industries Utilising Non-Asbestos Fibre, Non-asbestos Gasket · Oil and Gas· Chemical Processing· Petrochemical Industry· Process Industry Dimensions of Non-Metallic Flat Gaskets, ASME B16.21 to be used with Raised Face flanges ASME b16.5  Gasket Dimension Class 150 to 900 NPS 1/2 to 24NPSd1d2Class150Class300Class400Class600Class9001/22148545454643/427576767677013367737373791.1/44276838383891.1/24886959595982601051111111111432.1/273124130130130.21653891371491491491683.1/2102162165162162 411417518117819420651411972162132412486168222251248267289821927930830532135910273340362359400435123244104224194574981435645148648349252116406514540537565575184575495975946136382050860665464868369924610718775768791838 General notes:· Dimensions are in millimeters unless otherwise indicated.· d1 = Inside diameter.· d2 = Outside diameter.· Dimensional tolerances outside diameter NPS 12 and smaller: +0 / -1.5 mm.· Dimensional tolerances outside diameter NPS 14 and larger: +0 / -3.0 mm.· Dimensional tolerances inside diameter NPS 12 and smaller: ± 1.5 mm.· Dimensional tolerances inside diameter NPS 14 and larger: ± 3.0 mm.· Thickness (t) specified by customer. /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
