We offer Graphite Packing. Product Name:Expanded Graphite Packing Equipment: Extensive use for various equipment. Sector of the industry: Fossil oil, chemical industry, power plant, steel mill etc. Medium: The products are almost suitable to all mediums, such as hot water, fluid under high temperature and pressure or low temperature, steams, ammonia, hydrogen and organic solvents etc. Dimension: 3×3mm--50×50mm;Others can be produced according to client's requirement. Expanded graphite packing is woven crisscross by flexible graphite yarn. It has the following advantages: versatility, flexibility, good lubricity and the thermal conductivity, low friction coefficient, high intensity. But according to different requirements, it can be reinforced by 304, 316 L, carbon fiber, nickel alloy thread etc. Technical data:(due to the practical application of different working conditions, the following parameters is for reference only) PARAMETER VALUE Pressure 45 Mpa Working temperature -185℃ ~ +650℃ Velocity 20 ms PH 0- 14

We offer Expandable Graphite Powder. Expandable Graphite Powder Expandable graphite is a kind of graphite product which takes natural flake graphite as raw material and is treated by chemical or electro-chemical technology. When it is under high temperature, it can expand 150-400 times in volume instantaneously, flake graphite becomes vermiform graphite which is loose in structure, porous, curved, with large surface area, high surface energy and strong adsorptive power. The vermiform graphite pieces can be inlaid by themselves. In this way, its flexibility, resilience and plasticity are increased. It is a high-quality material for making flexible graphite sheets and various sealing components, it can also be used for heat preservation in metallurgical industry and as fire-extinguishing agent for fire fighting. Application: 1.As additive of heat preservation in metallurgy 2.The raw materials of flexible graphite foil 3.Absorbing materials of battery 4.Lubricant and additive materials 5.Fire prevention meterial Feature: It can be processed into various products with abilities of heat-insulating, lubricant or bearing the high-temperature, chemical stability because of its excellent expandability. Expandable:200250300mlg

We offer Spiral Wound Gasket. Product Name:Spiral Wound Gasket Standards:GB4622.2-93, JB4705-92, JBT4719-92, SH3407-96, HG20610-09, JBT90-94, ANSI, API, JPI, JIS, DIS, etc. Or client request. Section Plane : Steel Tape Material Inner&Outer Ring Material:OCr13, 304SS, 304LSS, 316SS, 316LSS, 316TiSS, 321SS, Others Filler material:Asbestos Band, Expanded Graphite, Teflon Band, Non-Asbestos, Mica, etc. Spiral wound gasket structure: Spiral Wound Gasket with outer ring is manufactured by wrapping alternating layers of thin stainless steel and a soft gasket filler material such as graphite or PTFE. Material of outer ring can be carbon steel, SS304, SS316L Appication: spiral wound gasket is the best in the compression resilient in all the half-metal seal gasket, which is made by the steel tape and different kinds of packing material. We can make its structure density according to the demand of different locking force, and we use the outer ring to control the maximum compact degree. So it can be well suit the rough flange face, especially suit the situation of unbalance load, loose of joint force, temperature and pressure change periodically, concussion and shock. It is used in flange joint of valve, pump, heat exchanger, tank, and hand hole. It is widely used in the fields like petrochemical industry, machine, electric power, metallurgy, ship-building, medicine, atomic energy, space navigation.

We offer Composite Graphite Sheet. Tangled reiforced graphite sheet is comprised of expanded graphite sheet and tanged steel sheets(SS304316316L). It has character of thermally stability, high strength and no cold flow etc. It offer excellent sealing capabilities under extreme conditions with a longer life and less maintenance.It is an ideal material of all kinds of reinforced graphite gaskets, engine heat gaskets cylinder gaskets of compressors & internalcombustion engines etc. Work condition temperature:-200~600°C Pressure:500 Bar PH:0 - 14 1)Graphite sheet is Selected from the high purity natural flake graphite and SS304316316LTinplate tanged, flat foil or wire mesh inert. There are two basic types: mechanically bond (Tang inserted) and adhesive bond. 2)They are made through the advanced chemical treatment and mechanical procedure without fibers, binders or other additives. 3) It offer excellent sealing capabilities under extreme conditions with a longer life and less maintenance. 4)Made for packing rings and various kinds of gaskets. It is used widely in chemical, automotive and pump, valve industries. As a superior replacement for asbestos, new more applications are Being identified daily. 5)Temperature: -240~500°C under oxidizing environment
