Flat gaskets

Product catalog summary
Overview: The document provides detailed information on flat and flange gaskets, focusing on materials, manufacturing processes, and applications. It includes specifications for various materials used in gasket production, their properties, temperature ranges, thicknesses, and approvals.
Materials and Properties:
  • PTFE (Teflon®): Known for low friction, chemical resistance, and a wide temperature range (-200°C to +260°C). Enhanced with glass fiber, bronze, carbon, and molybdenum disulphide for improved mechanical properties.
  • Modified PTFE: Suitable for high-risk applications with high temperature and pressure. Variants include those with hollow glass microspheres, barium sulphate, and silica, each offering specific benefits like high compressibility and mechanical resistance.
  • Fibre Materials: Asbestos-free, with high resistance to deformation. Includes aramid fibers with NBR, glass fibers with NBR, and graphite with Kevlar fibers, each suited for different industrial applications.
  • Expanded Graphite: Reinforced with stainless steel, suitable for high temperatures and mechanical loads, with excellent performance in extreme conditions.
  • Elastomers: Various types like natural rubber, EPDM, neoprene, and silicon rubber, each with specific properties like tensile strength, elongation, and temperature resistance.
Manufacturing Processes: Gaskets are manufactured by cutting sheet metal or machining rod or pipe, depending on the material and application requirements.
Applications: Gaskets are used in a wide range of industrial machinery and flow control applications, including chemical, food, pharmaceutical, and petrochemical industries.
Standards and Approvals: The document lists various standards and approvals for materials, such as FDA, TA-Luft, DVGW, BAM, and others, ensuring compliance with industry requirements.
Tables and Dimensions: Includes tables for gasket dimensions according to DIN 2690 and ANSI B16.5 standards, providing detailed measurements for different nominal sizes and pressure ratings.
