HLG124 Asbestos metal spiral wound gasket
This type of gasket uses asbestos as a filler and has a wide range of uses, such as pipeline flanges, pressure vessels, heat exchangers and various valve covers. <br> The maximum working pressure can reach 42.0MPa. <br> The maximum operating temperature can reach 600°C. <br>
HLG216 Non-asbestos metal spiral wound gasket
Due to the use of non-asbestos as the filler, in addition to heat resistance, other properties are the same as asbestos gaskets, and the design and use conditions are the same as asbestos. It is a static sealing element for flange connections such as pipes, heat exchangers, and towers. Used in petroleum, chemical, electric power, shipbuilding, steel and other sectors.
HLG436 PTFE spiral wound gasket
PTFE has strong corrosion resistance. For example, it can be used in corrosive vacuum piping if it is combined with strong corrosion resistance metals such as Monel, titanium, and nickel. It is a static sealing element at the flange joints of pipelines, heat exchangers, towers, etc., and is widely used in petroleum, chemical, electric power, shipbuilding, steel and other sectors. It is especially suitable for corrosion resistance and sealing of vacuum parts.
HLG336 Graphite metal spiral wound gasket
Expanded graphite has the advantages of high temperature resistance, corrosion resistance, flexibility and good resilience. In the spiral wound gasket series, its service temperature is relatively high. It is most suitable for use in occasions where the temperature changes. It is a static sealing element at the flange connection of pipelines, heat exchangers, tower tanks, etc., and is widely used in petroleum, chemical, electric power, shipbuilding, steel and other sectors. It is especially suitable for high temperature and high pressure steam, LPG, and alternating hot and cold temperature differences. <br> Maximum operating temperature: oxidizing gas: 450°C; non-oxidizing gas: 800°C.
HLG104-M Special-shaped metal spiral wound gasket
It is a gasket specially used for boilers, manholes, hand holes, valve covers, etc. The maximum working pressure can be 42.0MPa. The operating temperature can be determined according to the material of the metal belt and filler. Because there is no inner and outer ring reinforcement, the effect is particularly good when used in L-shaped or U-shaped grooves.
HLG114-EX Heat Exchanger Gasket
It is a kind of gasket specially used for heat exchangers. It is based on a metal tubular gasket or a packing gasket, and there is a wound gasket on the outside, so it has the advantages of two types of gaskets. <br> Maximum pressure: 25Mpa<br> Maximum temperature: 550°C
The metal-coated gasket is made of asbestos paper, expanded graphite, ceramic fiber, tetrafluoroethylene, etc. as the filler, and is made of metal sheets of various materials such as stainless steel, tinplate, and copper. It is widely used in water vapor, coal gas, petroleum gas, and solvents. Pipe flanges for steam, pressure vessels, sealing covers for heat exchangers, and cylinder heads for internal combustion engines and compressors. The gasket can be manufactured with a diameter of 15mm to 5000mm and a thickness of 2mm to 8mm. See the attached drawings for various types. The applicable medium, pressure and temperature of the gasket vary with the material used. <br> Maximum temperature: 1300°C Maximum pressure: 10Mpa
