SS316 stainless steel metal corrugated gasketMetal corrugated composite gasketA metal composite gasket, also known as a corrugated live pressure gasket, is first pressed into a concentric corrugated shape from a metal sheet, and mechanically supported by the corrugations. Its rebound performance is determined by the form used, metal thickness, corrugation spacing, and corrugation height. According to the needs, a soft sealing layer material can be added to make the metal corrugated composite gasket have better compression rebound performance. Due to the contact with other sealing surfaces being multiple concentric circles, it has a labyrinth sealing effect. Depending on different media and working conditions, flexible graphite can be selected PTFE、 Asbestos free board or other soft metals are pasted on both sides of the gasket to achieve better sealing effect by utilizing the sealing properties of the soft covering layer and the strength and elasticity of the metal. In most cases, we use graphite as the sealing layer. When the medium reacts with graphite or requires a clean environment, we recommend choosing the recently launched expanded PTFE adhesive layer. Generally, it does not require a large compressive force to achieve the sealing effect.
Metal corrugated composite gaskets can also be used directly without adhesive sealing layers, achieving good sealing effects. Compared with toothed composite gaskets, corrugated composite gaskets, etc., they have better compression rebound performance, especially in large-sized smoke and gas pipelines, low pressure, high temperature, or twisted flanges, with more significant sealing effects.
SS316 stainless steel metal corrugated gasketT-rib graphite corrugated belt toothed combination gasket metal toothed combination gasket belongs to a type of metal composite gasket. Generally, a precision lathe or milling machine is used to process the two sides of the metal flat gasket into concentric 90 degree angle sawtooth grooves to form a waveform. Due to the contact with other sealing surfaces being a line contact of multiple concentric circles, it has a labyrinth sealing effect. Depending on different media and working conditions, flexible graphite can be selected PTFE、 Non asbestos board or other soft metals are pasted on both sides of the gasket to achieve better sealing effect by utilizing the sealing properties of the soft covering layer and the strength and elasticity of the metal. In most cases, we use graphite as the sealing layer. When the medium reacts with graphite or requires a clean environment, we recommend choosing the recently launched expanded PTFE as the adhesive layer. Generally, it does not require a large compressive force to achieve the sealing effect. The toothed combination gasket can also be used directly without a covering sealing layer to achieve good sealing effect, but it is prone to damage the surface of the flange in high-pressure situations. So generally, it is required that the roughness of the sealing surface be Ra1.6um or above.
SS316 stainless steel metal corrugated gasketWe can also produce special materials such as stainless steel 304L, 321316TI, 309347410, duplex steel (220531803), Monel MONEL (400), Inconel INCONEL (600625), INCOLOY (800825), Hastelloy HASTELLO (B2, C276), titanium (T2) and other special stainless steel or alloy materials that are required for special working conditions such as high temperature and strong corrosion.
Performance characteristics of metal toothed composite gaskets: 1. Low pre tightening force, even in high-pressure environments, it has good sealing effect, especially suitable for high temperature, high pressure, and alternating working conditions. It is an ideal substitute for traditional metal wrapped gaskets and metal coated gaskets. 2. The metal toothed combination gasket does not damage the sealing surface and is easy to disassemble.
3. The metal tooth body can be reused, which is of great significance for larger gaskets or gaskets made of special materials such as heat exchanger gaskets.
Application scope of metal toothed composite gasket: The toothed composite gasket is mainly used for sealing the connections of medium, high pressure, and high temperature pressure vessels, heat exchangers, condensers, and pipeline flanges in industries such as petroleum, chemical, metallurgical, power, shipbuilding, and machinery.
Types of metal wrapped gaskets: basic metal wrapped gasket, metal wrapped gasket with outer ring, metal wrapped gasket with inner ring
Metal wrapped pads with inner and outer rings, for heat exchangers (with ribs), and shaped metal wrapped pads.
The metal wrapped gasket (basic type) is made of high-quality SUS304, 316L ("V" - or "W" - shaped) metal strips and other alloy materials that overlap and spiral wrap with soft materials such as graphite, asbestos, polytetrafluoroethylene, and asbestos free. The metal strips are fixed at the beginning and end by spot welding.
Xinhong Metal Wrapped Gaskets come in a complete range of models. Metal wrapped gaskets have a wide range of properties such as oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance, electrical insulation, and vibration resistance. They are made by stacking V-shaped or W-shaped stainless steel strips with non-metallic fillers, spiral winding, and spot welding at the beginning and end. It has good compression resilience and is suitable for sealing parts with severe temperature and pressure fluctuations. It is a static sealing element at flange connections such as pipelines, valves, pumps, heat exchangers, towers, manholes, and handholes. Sealing gasket series metal winding gasket
