JinSeal Also Manufactures Kinds of Sealing Gaskets Included Non-Metallic Gasket Like PTFE Gasket, Non Asbestos Free Gasket, Graphite Gasket in Flat Full Face or Raised Face Types. The Gaskets Are All Manufactured Accordingly to Asme B16.20, EN1514 or JIS Standard.
Non-Metallic Ring Gaskets Are Also Called As Soft Cut Gasket, and They Are Always Cut from a Soft Sheet Material, for Example Graphite, Rubber, PTFE, Compressed Non-asbestos Fiber (CNAF). the Gaskets Can Be Provided for Full Face or Raised Face Types Based on the Finished Flange Face. Full Faced Gaskets Are Suitable for Flat Face (FF) Flanges While Flat Ring Gaskets Are Suitable for Raised Faced (RF) Flanges.
Soft Flat Gaskets Are Used with Low-pressure Flanges and in Low Temperature at Lowest Cost Compared with Other Sealing Gaskets. There is Rubber Gasket, Non-asbestos Gasket (CNAF), PTFE Gasket, Graphite Gasket, PTFE Envelope Gasket, Etc. With a Full Range of Cutting Capabilities Including Die Cutting, Waterjet Cutting, Laser Cutting and Knife Cutting, We JinSeal Can Provide Different Shapes of the Flat Gaskets.
Non-Free Gasket Cut from a Compressed Non-asbestos Jointing Sheet Which Contains Fibers Blended with Suitable Heat Resistant Binders and Some Rubber Contents. They Are Used for Higher Temperature Environment Compared to Rubber Gasket. Non-Asbestos Gaskets Sheet Are a Replacement of Asbestos Gasket As Asbestos is Harmful to Human and Forbidden to Be Used in Industries.
PTFE Ring Gasket Circle Cut or Dies Cut Type Gasket, and It Has Excellent Chemical Resistance, Electrical Property. PTFE Gaskets Are Used in the Presence of Aggressive Chemicals Such As Acids and Alkali by Offering Non-corrosive, Non-wetting, Non-contaminating Function. The Gaskets Can Be Used for Environment of the Temperature from -200℃~+260℃ and Also Can Be Used for Medical and Food Industries.
Graphite Ring Gaskets Are Also Cut from Pure Flexible Graphite Sheet and Good for High-Temperature Applications. the Pure Graphite Gasket Has Excellent Resistance to Corrosive Chemicals, High Temperature and High Pressures, As Well As Perfect Thermal Conductivity. They Can Be Used in a Variety of Industries Such As Refineries, Chemical and Petrochemical Plants, Paper Mills Mines and Other Fields.
Envelope Gasket is Made Up of a Ring Gasket with Usually 2mm Thick and a Thin PTFE Envelope with 0.5mm Thick Leaves. the Ring Gasket’s Material is Always in Rubber or Non-asbestos, and the PTFE Envelope is Commonly Supplied in Slit or Milled or U-shape Types. the PTFE Envelope Can Protect the Ring Gasket by Giving Good Chemical Resistance. in This Way, the Gasket is Ideal for Use in Equipment Employing Flanges Made from Alloy, Standard Steel, Glass-lined, Plastic, Ceramic, Conical-end Pipe Etc.
Rubber Gaskets Are Always Cut from Rubber Sheet or Die Cut from Rubber Raw Material. There Usually is EPDM, Viton, Neoprene, Silicone, NBR and the Gaskets Are with the Properties of the Corresponding Rubber Which is for Low Temperature and Pressure. but It Provides a High Degree of Deformation Without Permanent Damage or Loss of Attributes.
