Reinforced Spiral Wound Gasket also known as graphite reinforced composites from high-strength flexible graphite gasket reinforced composite plate by precision cutting, with the packet can be processed into a side edge of outsourcing. With good sealing performance and operability, and low pre-pressure and non-stick used in the flange sealing surface, the installation of easy-to-use pads. To adapt to hot water, high temperature, high pressure steam, hydrogen, ammonia, solvents, hydrocarbons, such as ultra-low temperature liquid medium.
Spiral Wound Gasket with Inner And Outer Ring adopts high-quality SUS304 or SUS316 ("V" or "W"shape) metal strips, other alloy materials and some flexible materials like graphite, asbestos, PTE and non-asbestos, which are overlapped and wound spirally with each other. The metal strips are fixed on the initial and terminal ends by means of spot welding. Spiral Wound Gasket has the best resilien ce among the semi-metal hermetic gaskets. Its structural density can be made subject to different locking forces. Also the internal and external steel rings can be used to control its maximum compaction. It's not demanding for the surface precision of the flange sealing surface contacting the spirally-wound gasket. It's especially applicable for such occasions as uneven load, slack joint, periodical changes of temperature and pressure, impact or vibration. It's an ideal static seal element for flange connection in valves, pumps, heat exchangers, towers, manholes,handholes and so on.
PTFE Teflon Gasket has strong corrosion resistance and friction-resistance,By adding filler such as glass fiber,carbon fiber,copper powder,graphite,asbestos,MOS2,AL2O3,carbon powder,ceramic fiber,metal powder,polyamide,PS,the hardness,compression strength and abrasion resistance of the products is improved ,in addition,it will have good heat conductivity and low heat expansion coefficient.
