Brief introduction: HLG852 multi-layer graphite composite board is a multi-layer graphite and stainless steel flat composite reinforced graphite plate, can be widely used in petrochemical, power generation, shipbuilding, paper and other industries of steam pipelines, boilers, heat exchangers, heating equipment, auditions, valves, flues and other parts of the sealing material has high requirements for high temperature resistance and sealing performance. Performance parameters: Thickness: 1.0mm~3.0mm or customized as needed Size: 1500mm×1500mm or customized as needed Graphite ash: ≤2% Graphite purity: ≥98% Compression ratio: 45% Springback rate: 37% Leakage rate: 1.15*10-4 Maximum use temperature: 580 °C (working temperature ≥ 480 °C, please confirm with our company whether it is applicable) Maximum operating pressure: 250 bar

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.
The maximum working pressure can reach 42.0MPa.
The maximum operating temperature can reach 600°C.

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.

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.

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.
Maximum operating temperature: oxidizing gas: 450°C; non-oxidizing gas: 800°C.

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.

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.
Maximum pressure: 25Mpa
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.
Maximum temperature: 1300°C Maximum pressure: 10Mpa

HLG650 selects various materials of metal and is machined into various forms of metal sealing gaskets. Suitable for sealing parts of high temperature, high pressure and strong corrosive pressure vessels, valves, cylinder heads, etc. The maximum working pressure of R-shaped oval and octagonal gaskets is 10000PSI. The maximum working pressure of RX and BX type self-tightening gaskets is 15000PSI.

A flat ring with concentric serrations made of various metals. Use when the bolt force is not enough to seal the flat gasket, because it only contacts the flange surface at the serrated peak. Usually used to connect to the valve cover and flange of the equipment. Three types of cross-sections in the table on the right are available.

PTFE coated gasket is a combination of asbestos, rubber, non-asbestos and other soft gaskets and PTFE. It has excellent corrosion resistance and good compression rebound rate, making it widely used in various A kind of strong acid, strong alkali, strong oxidation, chlorine gas and sealing of non-contaminated media.

The 850 series is punched out of pure graphite board or graphite composite reinforced board. Excellent corrosion resistance, high and low temperature resistance; good compression resilience, good strength. It is a sealing element for pipes, valves, pumps, pressure vessels, heat exchangers, condensers, etc. It can also be cut into gaskets with complex shapes, such as gaskets for water level gauges and gaskets with bolt holes.
The 850E series is an improvement of the 850 series. The inner and outer rings are covered with metal foil. Maintain the original excellent performance, and can effectively prevent the penetration of the medium.
Common thickness 1.5mm, 2.0mm, 3.0mm, 4.5mm.
