A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Metallic Gaskets: \"Metallic Gaskets\" are gaskets that are fabricated from one or a combination of metals to the desired shape and size. Common metallic gaskets are Spiral Wound Gaskets, Double Jacketed Metal Gaskets, Solid Metal Gaskets, Corrugated Metal Gaskets, Ring Type Joint Gasket used for heat exchangers, compressors, condensers, pumps, valves and turbines. These metallic gaskets are suitable for high pressure & temperature applications and require high bolt load to seal. Types: � Spiral Wound, Double Jacketed, Solid Metal gaskets, Corrugated Metal Jacketed Gaskets, Ring type joint Gaskets Non Metallic Gaskets: \"Non Metallic Gaskets\" or \"Soft Gaskets\" are gaskets that are easily compressed under a low bolt load. They are composite sheet materials that are suitable for a wide range of general as well as corrosive chemical applications. They are easily available either in sheet form or as gaskets that are cut accurately to any reasonable shape and size. Non metallic gaskets are usually manufactured from materials like arimid fiber, glass fiber, elastomers, teflon (PTFE), compressed asbestos fibre (CAF), flexible graphite etc. Types are: Non Asbestos, Asbestos, Flexible Graphite, PTFE, Viton, Silicone Rubber, Neoprene and Flange Gaskets.
[Spiral Wound Gasket] Material Filler: GRAPHITE, PTFE, INCONEL, etc. Hoop: SUS304, SUS316L, etc. Feature The spiral wound gasket is the most ideal type having flexibility and recovery which are essential for high temperature and high pressure among semimetal gaskets. It is wound in spiral combined with V-type metal thin hoop and non-ferrous material filler. The winding start part and end part are wound by the hoop over several times and then both edge is processed by spot welding to make the gasket. The gasket has outstanding capability as it features unique structure with elastic metal and flexible filler. - Outstanding capability for high temperature and high pressure - Automatic flexibility and recovery from the change of temperature, pressure, vibration and working conditions - Efficient production for any type of dimensions such as round or oval type, etc. - Outstanding sealing capability as it is produced according to the pressure of unbalanced flange. - Hoop and Filler materials can be selected according to special operating conditions.

RTJ Kammprofile Gaskets A composite gasket that utilises a serrated metal core with a soft facing material The metal core is machined on each contact face with concentric serrations, providing high pressure areas This ensures the soft coating flows into any imperfections in the flange even at relatively low bolt loads The soft facing material is engineered to compress into the serrations on the core and form a thin film across the peaks creating the ideal sealing density in the grooves of the profile The result? You get a gasket that combines the benefits of soft cut materials with the advantages of seal integrity associated with metallic gaskets Expanded graphite is the most common facing material used for Camprofile gaskets However, other materials can also be used. For instance, PTFE for chemically aggressive duties and mica for high temperature services
SPIRAL WOUND GASKET The spiral wound gasket is suitable for use across a wide pressure range and is therefore virtually applicable. The spiral wound gasket can be used to seal fluid pressures up to 250 bar and cryogenic temperatures as low 200C and up to elevated temperatures 550C. Due to its sturdy design the spiral wound gasket is simple to install without causing damage (although extra care should be taken during transportation and installation of large diameter gasket without guide rings). The outer guide ring serves to locate the spiral element centrally on the flange faces and prevent blow-out. By combining different winding materials and metals the gasket can be tailored to a wide variety of operating conditions. Due to its non-adhesive character the gasket is easy to remove after service. The gasket does not cause damage to the flange faces. BENEFITS OF THE CENTRING RING The spiral wound gasket outer centering ring provides the following benefits: Optimum location between the bolts. Protection of the spiral wound element. Additional security against gasket blow-out. Acts as compression limiter preventing overloading and over compression of the spiral wound element. Prevents radial-flow of soft fillers, such as P.T.F.E. For these reasons it is preferable to use spiral wound gasket with outer centering rings. On the outer ring is marked with nominal size, pressure class, standard and materials. BENEFITS OF THE INNER RING The spiral gasket inner ring provides the following benefits: Prevents radial-flow of soft fillers, such as P.T.F.E. Reduces turbulence-minimizing flow resistance and crevice corrosion. Acts as a heat shield when the spiral wound gasket is subjected to high temperatures. Inner and outer rings are particularly recommended for use on spiral wound gaskets exceeding class 600lbs, but specifically recommended for high temperatures and pressures to optimize the operational reliability of the spiral wound sealing element. MATERIAL SELECTION Material selected for the inner ring and winding metal is usually the same as the flange metal, in order to prevent corrosion and differential expansion problems. The outer centering ring is generally manufactured from carbon steel with an anti- corrosion treatment; however, the ring may also be manufactured in the same metal as the flange to prevent corrosion problems.

According to the different medium, w can choose flexible graphite, PTFE, non-asbestos, or other soft metal, to sick to the two faces of the gasket. It can directly be used without sealing layer, and the effect is good. But under the high pressure occasion, it will be easy to do damage to the surface of the flange. 410 basic type Kammprofile gasket 410L Kammprofile gasket with outer ring (integral type) 410LM Kammprofile gasket with outer ring (split type) Model 410LM split type Metal toothed gasket with outer ring, can choose richer metal, e.g. carbon steel, as the outer ring, and the outer ring thickness can be 1.5mm, more flexible and economic than the integral type 410L, and the lining metal can be repeatedly used. Product application: GOT toothed combination gasket is the first choice gasket under relatively low preload power, the soft surface of the sealing layer can avoid the direct touch between metal and metal, which is combined reliably and compactly, to protect the metal flange from damaged, even under extremely high load. The toothed combination gasket is especially suitable for the flange connection in thermal exchanger, container, and reaction vessel under high temperature, high pressure, and the working condition altering occasions. It is an ideal substitution for traditional metal jacketed gasket.
