管法兰用金属波齿组合型垫片 -非标定制-椭圆型八角金属环垫片 Metallic wave tooth combined gaskets for pipe flanges non-standard custom - elliptical octagonal metal ring gaskets --------------------------------------------------------------------------------------------------------------------------------Metal tooth a metal composite gaskets, gasket composite wave first commonly used special precision lathe or milling machine in the two aspects of metallic flat gasket into the wave shape of concentric grooves, up and down sides of tooth staggered, can make it has better compression resilience, is due to contact with other sealing surface of multiple concentric line contact, so have labyrinth seal effect,According to different media and working conditions, flexible graphite, PTFE, non-asbestos plate or some other soft metal can be selected and pasted on the second side of the gasket.
The advantages of the sealing property of the soft covering layer and the strength and elasticity of the metal can be used to achieve better sealing effect. In most cases, we recommend graphite as the sealing layer.When the medium reacts to graphite or requires a clean environment, we suggest choosing the newly launched expanded tetrafluoro with excellent performance as the adhesive layer. The metal wave tooth composite gasket generally does not need a great compression force to achieve the sealing effect. The wave tooth composite gasket can also achieve good sealing effect without adhesive sealing layer directly. Compared with the tooth shape composite gasket, it has better compression resilience, especially in large size smoke and gas pipelines, low pressure, high temperature, or uneven twisted flanges. It has a more significant sealing effect. Special working conditions such as high temperature, strong corrosion and other special materials of metal wave tooth composite gasket we can also produce some of the following special materials can be required:
Stainless steel 304L, 321,316Ti, 309,347,410, duplex steel (2205,31803), Monel (400), indium nickel INCONEL (600,625), INCOLOY (800,825), Hastello alloy (B2, B2)C276), titanium (T2) and other special stainless steel or alloy materials.
Metal wave tooth composite gasket performance characteristics: 1. Excellent compressive elasticity, excellent sealing performance can be achieved even under low compression force, especially suitable for high temperature, high pressure, alternating working conditions is an ideal substitute for traditional metal wound gaskets and metal coated gaskets. 2. The metal wave tooth composite gasket does not damage the sealing surface and is easy to disassemble. 3. A wide range of use can be used for low and high temperature (-200°C~+700°C), can also be used for low and high pressure (vacuum ~25Mpa).The wave-tooth composite gasket manufactured from the corresponding metal frame material can be used in most corrosive fluid applications.
4. The metal wave tooth body part can be reused, which is of great significance for larger gaskets or gaskets of special materials such as heat exchanger gaskets.
Application range of metal wave tooth composite gasket: Metal wave teeth composite gasket is mainly used in petroleum, chemical, metallurgy, electric power, shipbuilding, machinery and other industries, high pressure and high temperature pressure vessels, heat exchangers, condensers and pipe flanges of the joint sealing.
