Product Name: Gasket Material: All kinds of materails Type: Gasket Trademark: CHANYAT Transport Package: Wooden and Acc. to Customer's Requirements. Origin: China Product Description Types of Gaskets Materials for gaskets can be divided into three main categories:1.Non-metallic types 2.Semi-metallic types3.metallic typesmetallic gaskets are fabricated from one or a combination of metals to the desired shape and size. Often used metallic gaskets are ring-type-joint gaskets (RTJ). They are always applied to special, accompanying flanges which ensure good, reliable sealing with the correct choice of profiles and material.ASME B16.20 covers materials, dimensions, dimensional tolerances, and markings for metallic and semi-metallic gaskets.Semi-metallic gaskets are composites of metal and non-metallic materials. The metal is intended to offer strength and resiliency, while the non-metallic portion provides conformability and sealability. Often used semi-metallic gaskets are spiral wound and camprofile, and a variety of metal-reinforced graphite gaskets.Semi-metallic are designed for almost all operating conditions and high-temperature and pressure applications, and are used on raised face, male-and-female, and tongue-and-groove flanges.ASME B16.20 covers materials, dimensions, dimensional tolerances, and markings for metallic and semi-metallic gaskets.Non-metallic gaskets are usually composite sheet materials are used with flat-face and raised-face flanges in low Pressure Class applications. Non-metallic gaskets are manufactured from arimid fiber, glass fiber, elastomer, Teflon (PTFE), graphite etc.. Full-face gasket types are suitable for use with flat-face flanges. Flat-ring gasket types are suitable for use with raised face flanges.ASME B16.21 covers types, sizes, materials, dimensions, dimensional tolerances, and markings for non-metallic flat gaskets.only lists part:Spiral-Wound Gasket Materials:Carbon steel, 304 SS, 304L SS, 309 SS, 310 SS, 316L SS, 317L SS, 347 SS, 321 SS, 430 SS, Ni-Cu (Monel 400, Grade 400), Nickel 200, Titanium, 20Cb-3 alloy, Ni-Mo (Hastelloy B, Grade B2), Ni-Mo-Cr (Hastelloy C, Grade C-276), Ni-Cr-Fe (Inconel 600, Grade 600), Ni-Cr-Fe-Cb (Inconel 625, Grade 625), Ni-Cr-Fe-Ti (Inconel X-750, Grade X-750), Ni-Fe-Cr (Incoloy 800, Grade 800), Ni-Fe-Cr-Mo-Cu (Incoloy 825, Grade 825), Zirconium, Nonmetallic Filler Materials:Polytetrafluoroethylene, Vermiculite, Phlogopite (magnesium mica), Flexible graphite, CeramicClass 150NPSInner RingSealing ElementOuter RingD1D2D3D41⁄214.219.131.847.83⁄420.625.439.657.2126.931.847.866.811⁄438.147.860.576.211⁄244.554.169.985.9255.669.985.9104.921⁄266.582.698.6124381101.6120.7136.74106.4127149.4174.85131.8155.7177.8196.96157.2182.6209.6222.38215.9233.4263.7279.410268.2287.3317.5339.912317.5339.9374.7409.714349.3371.6406.4450.916400.1422.4463.6514.418449.3474.7527.1549.420500.1525.5577.9606.624603.3628.7685.8717.6Class 300NPSInner RingSealing ElementOuter RingD1D2D3D41⁄214.219.131.854.13⁄420.625.439.666.8126.931.847.873.211⁄438.147.860.582.611⁄244.554.169.995.3255.669.985.9111.321⁄266.582.698.6130.3381101.6120.7149.44106.4127149.4181.15131.8155.7177.8215.96157.2182.6209.62518215.9233.4263.7308.110268.2287.3317.536212317.5339.9374.7422.414349.3371.6406.4485.916400.1422.4463.6539.818449.3474.7527.1596.920500.1525.6577.9654.124603.3628.7685.8774.7Class 400NPSInner RingSealing ElementOuter RingD1D2D3D41⁄214.219.131.854.13⁄420.625.439.666.8126.931.847.873.211⁄438.147.860.582.611⁄244.554.169.995.3255.669.985.9111.321⁄266.582.698.6130.3381101.6120.7149.44102.6120.7149.4177.85128.3147.6177.8212.96154.9174.8209.6247.78205.7225.6263.7304.810255.3274.6317.5358.912307.3327.2374.7419.114342.9362406.4482.616389.9412.8463.6536.718438.2469.9527.1593.920489520.7577.9647.724590.6628.7685.8768.4Class 600NPSInner RingSealing ElementOuter RingD1D2D3D41⁄214.219.131.854.13⁄420.625.439.666.8126.931.847.873.211⁄438.147.860.582.611⁄244.554.169.995.3255.669.985.9111.321⁄266.582.698.6130.3378.7101.6120.7149.44102.6120.7149.4193.85128.3147.6177.8241.36154.9174.8209.6266.78205.7225.6263.7320.810255.3274.6317.5400.112307.3327.2374.7457.214342.9362406.4492.316389.9412.8463.6565.218438.2469.9527.1612.920489520.7577.9682.824590.6628.7685.8790.7Class 900NPSInner RingSealing ElementOuter RingD1D2D3D41⁄214.219.131.863.53⁄420.625.439.669.9126.931.847.879.511⁄433.339.660.588.911⁄241.447.869.998.6252.358.785.914321⁄263.569.998.6165.1378.795.3120.7168.44102.6120.7149.4206.55128.3147.6177.8247.76154.9174.8209.6289.18196.9222.3257.3358.910246.1276.4311.2435.112292.1323.9368.3498.614320.8355.6400.1520.716374.7412.8457.2574.818425.5463.6520.7638.320482.6520.7571.5698.524590.6628.7679.5838.2Class 1500NPSInner RingSealing ElementOuter RingD1D2D3D41⁄214.219.131.863.53⁄420.625.439.669.9126.931.847.879.511⁄433.339.660.588.911⁄241.447.869.998.6252.358.785.914321⁄263.569.998.6165.1378.792.2120.7174.8497.8117.6149.4209.65124.5143177.82546147.3171.5209.6282.78196.9215.9257.3352.610246.1266.7311.2435.112292.1323.9368.3520.714320.8362400.1577.916374.7406.4457.2641.418425.5463.6520.7704.920476.3514.4571.5755.724577.9616679.5901.7Class 2500NPSInner RingSealing ElementOuter RingD1D2D3D41⁄214.219.131.869.93⁄420.625.439.676.2126.931.847.885.911⁄433.339.660.5104.911⁄241.447.869.9117.6252.358.785.914621⁄263.569.998.6168.4378.792.2120.7196.9497.8117.6149.42355124.5143177.8279.46147.3171.5209.6317.58196.9215.9257.3387.410246.1270311.2476.312292.1317.5368.3549.4
