CIXI JIJIA SEAL is one of the biggest gasket manufacturers in China. We specialize in manufacturing many kinds of gaskets. such as Serrated metal gasket, Spiral wound gasket, Graphite gasket, PTFE gasket and so on. Serrated metal gasket is the preferred gasket when improved performance at low seating stresses is required. It feature excellent anti-blow-out properties liked with the reliablity of a solid metal-to-metal seal combined with a soft sealing face to provide a tighter joint. It is particularly suitatable for applications where high temperature, pressures and fluctuating conditions are encountered. Non-metal cover layers ensure that flanges are not damaged, even at extreme loads. Serrated metal gasket is an ideal replacement for problem applications associated with jacketed gaskets, for heat exchangers, vessels and reactors and various flange connections (pressure: 6.4~25 Mpa). The thickness of graphite or PTFE face is normally 0.5 mm. Depending on centreing ring with ch...

API gasket mainly is machined from solid metal in a variety of shapes and designed for high pressure, high temperature or highly corrosive applications by selecting the most suitable material and shape. It is designed to withstand exceptionally high assembly loads over a small area, thus producing high seating stresses. it include ring joint gasket, metal jacked gaskets, kammprofile gaskets and double jacked gaskets, . they are produced from different solid metal types, such as soft iron, SS304/316/316L, F5, low carbon steel, Monel 400, and other alloy items. Main use: General characteristic is installation area small and preload pressure high.

GOT Kammprofile gasket , generally processed to be concentric groove in the two faces of the stainless steel flat gasket by precise lathes. 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, ***** 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 po...

Pure graphite sheets / rolls are made from natural high-purity flake graphite through chemical and high temperature treatment, molding or rolling without any adhesives. With long life and low maintenance costs, it is still of excellent sealing performance in the harsh working conditions.。 Product Applications： It can be used as semi-finished products for manufacturing graphite packing rings and various types of gaskets. Widely used in chemical, automobile, pump and valve industries. Temperature： -240～450?C Oxidizing environment -240～3500?C Non-oxidizing environment PH Value： 0 - 14

Metal gaskets include corrugated metal gaskets, metal serrated gaskets and metal ring gaskets. Corrugated metal gasket is the concentric waveform ring processed from a flat metal ring through molding, rolling or turning, with the nonmetals like the expanded graphite or PTFE pasted on the surface. Compared to the serrated gasket, its inside linings are of a variety of thickness, such as 3mm, 2mm, 1mm, 0.5mm, etc., and the pitch of waves differs in accordance with the width of metal sealing surface, generally being 3mm, 4mm, and 6mm. Product Applications: This product has been proven to be of reliable and effective sealing performance when it is put in flanges and switch devices, especially of stronger sealing property in the large smoke and gas pipelines, flanges under low pressure or high temperature, or distorted flanges. It can also avoid the problem that non-metallic gaskets are difficult to install and use in large pipelines. ◆Outstanding mechanical strength and the...

Metal jacketed gasket, filled with the flexible graphite, ceramic fiber, asbestos and non-asbestos sheets as well as packed with the metal plates of stainless steel, tinplate, and red copper, is especially suitable for high temperature and high pressure sealing parts of heat exchangers, pressure vessels, etc. It can effectively not only prevent the gasket from falling apart and medium from erosion, but also increase the resistance to pressure. Gasket Types: Metal jacketed gasket Corrugated jacketed gasket Others Product Applications： Suitable for the heat exchangers, gas pipeline, cast iron flanges, cylinder heads, boilers and other containers. In the process of installation, the gasket is generally pressed to have 30% of deformation of the initial thickness, therefore effectively sealing the surface irregularity and overcoming small defects of flanges. It could be applied to various media by choosing different metals and fillers.

Reinforced graphite plate is compounded by the pure graphite sheet and metal dash plate, metal plate and wire mesh. According to customers’ size requirements, a variety of standard or non-standard gaskets of any particular shapes and sizes could be formed by cutting or stamping. It is of many excellent sealing performances, such as: thermal stability, self-lubrication, corrosion resistance, non-aging, and non-brittlement. It can be used stably for a long time in the harsh conditions, requiring minimal maintenance.
