FAQ

The graphite wrapping gasket prevents the film from being installed. Is it a thin one?
Graphite gasket: corrosion resistance, high temperature resistance; metal graphite spiral wound gasket: resistance to high pressure, corrosion resistant gasket is expensive metal graphite spiral wound gasket for semi metallic gasket recovery best gaskets high temperature metal graphite spiral wound, by V or W shaped steel strips with various fillers (graphite, asbestos PTFE), alternating wound together, the structure density can according to different requirements to lock force, and using internal and external steel ring to control its biggest compaction degree is not high, the flange gasket seal surface contact accuracy. The utility model is especially suitable for occasions with uneven load, easy loosening of joint force, periodic change of temperature and pressure, shock or vibration. It is the static seal of valve, pump, heat exchanger, tower, manhole, hand hole and so on. It is widely used in petrochemical, mechanical, electrical, metallurgy, shipbuilding, medical, nuclear and aerospace sectors.
Why does graphite conduct resistance?
Resistors are available, some are large, others are smallOf course, in addition to superconductivity
Many of the performance of vanadium battery better than lead-acid batteries, but what are its disadvantages?
On the use of super capacitor internal resistance is smaller, so the instantaneous release of the current can be greater. The super capacitor is not affected by the temperature, and all the chemical batteries are affected by temperature. When the ground temperature decreases, the internal resistance becomes larger. Supercapacitor is the pure physics principle, so it has longer life
What is the difference between the wave tooth compound gasket and the graphite gasket?
Special conditions such as extremely high temperature, strong corrosion and so on require special materials metal wave gear composite gasket, we can also produce some of the following special material requirements:321316TI, 309347410, 304L stainless steel, dual phase steel, Monel (220531803) MONEL (400), INCONEL (600625), nickel indium, INCOLOY (800825), Hastelloy HASTELLO (B2, C276), titanium (T2) and other special stainless steel or alloy materials.Graphite gasket made of pure graphite or metal plate (tooth plate, plate, net) reinforced graphite plate cutting or stamping, has many excellent sealing performance, such as thermal stability, self lubrication, corrosion resistance, not aging, not fragile, the use of long-term stability in the harsh working conditions, rarely need maintenance. The lining materials are made of different metal sheets. The type is optional, without hemming, inner wrapping, outer wrapping, inner and outer wrapping. Graphite cut gasket is from pure graphite plate drilling or cutting and it has good corrosion resistance, high / low temperature, compression elasticity and high strength good, complex geometric gasket circular is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, and condenser generator, air compressor, exhaust pipe, refrigerator etc..Graphite gasket is mainly used in various industrial pipe flanges, heat exchangers, valves, etc., and liquid level gauge, special flange on the level.Graphite gasket to stone line as the material, by weaving and shaping. Graphite gasket suitable for high temperature, high pressure, strong corrosive medium work all kinds of valves, pumps, reactors and other equipment packing box sealed.
How is the graphite plate machined?
Processing is the process of converting raw materials and semi-finished products into target requirements through certain processes and methods.
Do you have a lot of plates with silica ink?
Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal tar), sawdust (green salt produced when adding green silicon carbide) and other raw materials by smelting with resistance furnace at high temperature. Silicon carbide also rare minerals in nature, Mo sangshi. Silicon carbide, also known as carbon silica. Silicon carbide is the most widely used and the most economical kind of refractory materials in C, N, B and other non oxide refractory materials. It can be called "carborundum sand" or "refractory sand". At present, China's industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide two, are six square crystal, the proportion of 3.20 to 3.25, the microhardness is 2840 ~ 3320kg/mm2.
Why can graphite be used to power the appliance?
The bomb is used after special treatment of graphite carbon material, each carbon filament diameter is very small, only a few thousand of CM, therefore, can be in the high altitude long time floating. Because of its after grinding fluid energy is made, and after chemical cleaning, thus greatly improve the conductivity of the carbon filament. Carbon filament is not sticky, but can be attached to any surface. It is detonated by explosions or gunpowder, scattered in enemy positions, and destroyed enemy air defenses and power generation equipment. Carbon filament into electronic devices, internal cooling pipes and control system of the black box. Its warheads are destructive to stop on the runway including aircraft, electronic equipment, power plant power grid and all.
How to identify graphite impregnated PTFE and ordinary graphite?
Carbon can be oxidized by concentrated nitric acid to form nitrogen dioxide and carbon dioxide
