Spiral wound gasket is an important sealing element. Metal spiral wound gasket is widely used in petroleum, chemical, metallurgy, power generation, shipbuilding and other industries. It is the key component of static sealing of pressure pipes, valves, pumps, heat exchangers and other equipment. part. Therefore, the selection and use of high-quality spiral wound gasket products is of great significance to reduce and eliminate running, running, dripping and leaking, and to ensure the safety of the host equipment and the normal operation of the pressure pipeline.

Uneven pressing force is caused by a variety of factors, first is the human factor: asymmetric construction of the preload bolt, this factor can eliminate construction; theory on the flange pressed, the sealing surface is absolutely parallel to the practice, however,

Spiral-wound gaskets comprise a mix of metallic and filler material. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite)

Flange insulation group is one of the most common, effective and important connection forms in petrochemical plants, natural gas plants, offshore oil projects, etc. Various pipelines, pipe fittings, valves, instruments and equipment, flange insulation groups have unique performance and advantages. Use insulation kit seals on flanges to protect your pipes from the risk of leakage, sealing is achieved by the fit of flanges, insulating washers, bushings, washers, washers, bolts and nuts. Flange junction is connected and sealed to prevent medium leakage at the flange junction, as well as anti-corrosion and conductive insulation Protect.

The premise is simple in that a sheet of material has the gasket shape "punched out" of it. This leads to a very crude, fast and cheap gasket. In previous times the material was compressed asbestos, but in modern times a fibrous material such as high temp graphite is used.

The main products of rubber gaskets on the market are: silicone pads, nitrile rubber pads, fluororubber pads, and other rubber pads. Silicone rubber has outstanding resistance to up and down temperature, maintains good application elasticity in the temperature range of -70℃~+260℃, is resistant to ozone and weathering, and is suitable for sealing gaskets in thermal machinery.
