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.

High temperature resistant toothed composite gasket HLGR hot series
The high temperature resistant toothed composite gasket HLGR hot series is a special toothed composite gasket developed by Hengli Sealing to solve the high temperature field (≤1000°C) and flange sealing. It is especially recommended for large-size high temperature (≤ 1000°C) occasions. <br> The non-metallic composite layer of the high temperature resistant toothed composite gasket HLGR hot series is made of Canadian DURLON HT1000 high temperature oxidation resistant fiber tape and Germany SGL APX II (or France Capone Roland丨600) special oxidation resistant flexible graphite composite as shown in the figure below . DURLON HT1000 high-temperature oxidation-resistant fiber tape is compounded on the inner diameter side and outer diameter side of the toothed ring surface respectively, forming a home for the special oxidation-resistant flexible graphite compounded in the middle area of the toothed ring. <br> The metal toothed framework of the high temperature resistant toothed composite gasket HLGR hot series is generally Ni-Crfe alloy (Inconel 600) or Ni-Fe. Alloy (Incoloy800), the material specified by the customer can also be used.
High temperature resistant metal spiral wound gasket HLSW hot series
HLSW hot series of high temperature resistant metal spiral wound gaskets are special metal spiral wound gaskets developed by Hengli Sealing to solve flange sealing in high temperature (≤1000°C) occasions.
