Excuse me, Master, is there no standard or specification for graphite packing? What is the general basis for acceptance?
There are standards for graphite packing, but I don’t seem to know the specifications!
Graphite packing flexible graphite packing #flexible graphite packing
Also known as flexible graphite packing, it is made of flexible graphite threads woven through the heart. Expanded graphite packing has the advantages of good self-lubrication and thermal conductivity, small friction coefficient, strong versatility, good flexibility, high strength, and protection for the shaft.

Graphite packing is mainly made of various reinforced graphite wires, metal wires (steel wires, copper wires, nickel wires) and other reinforced graphite wires. Suitable for static sealing under high temperature and high pressure conditions.
Except for a few strong oxidants, it can be used to seal hot water, superheated steam, heat transfer fluids, ammonia solutions, hydrocarbons, cryogenic liquids and other media. It is also a unique universal sealing flexible graphite packing. What kind of high temperature and high pressure resistant graphite packing is good?
It has the performance of corrosion resistance, low temperature resistance and high temperature resistance, and also has good self-lubricating properties. It has the characteristics of high elasticity and small torque. It is a widely used sealing packing. Because this type of packing has low strength, it can be mixed and assembled with other packings to achieve better results.
Flexible graphite is expanded. Graphite packing is mainly made of various reinforced fibers, metal wires (steel wire, copper wire, nickel wire, carbon fiber, pre-oxidized wire, glass yarn ) and other reinforced graphite wires are carefully woven from raw materials. Pingdingshan Xinruida Graphite specializes in processing graphite parts. I hope this answer will be helpful to you! What is the difference between reinforced graphite packing and flexible graphite packing? Reinforced graphite
Flexible graphite packing is mainly made of various reinforced fibers, metal wires (steel wire, copper wire, nickel wire, carbon fiber, pre- Reinforced graphite threads such as oxygen yarn and glass yarn are carefully woven from raw materials. Suitable for dynamic sealing under high temperature and high pressure conditions. Except for a few strong oxidants, it can be used to seal hot water, superheated steam, heat transfer fluids, ammonia solutions, and hydrocarbons. Is graphite packing toxic?
It is not toxic, but it will be toxic if it absorbs too much dust. If you suffer from respiratory disease, you won’t get peas on your face, unless you are also allergic to C 囧 1) High temperature resistant type: The melting point of graphite is 3850±50℃, and the boiling point is 4250℃, even if it is burned by ultra-high temperature arc , the weight loss is very small, and the thermal expansion coefficient is also very small. The strength of graphite increases as the temperature increases. At 2000°C, the strength of graphite doubles. 2) Electrical and thermal conductivity: The electrical conductivity of graphite is one hundred times higher than that of ordinary non-metallic minerals. Thermal conductivity exceeds that of steel, iron, lead and other metal materials. The thermal conductivity decreases as the temperature increases, and even at extremely high temperatures, graphite becomes a thermal insulator. Graphite can conduct electricity because each carbon atom in graphite only forms 3 positive valence bonds with other carbon atoms, and each carbon atom still retains 1 free electron to transmit charge. 3) Lubricity: The lubrication efficiency of graphite depends on The size of graphite flakes, the larger the flakes, the smaller the friction coefficient and the better the lubrication efficiency. 4) Chemical stability: Graphite has good chemical stability at room temperature and is resistant to acid, alkali and organic solvent corrosion. 5) Plasticity: Graphite has good toughness and can be rolled into very thin sheets. 6) Thermal shock resistance: When graphite is used at room temperature, it can withstand drastic changes in temperature without being damaged. When the temperature suddenly changes, the volume of graphite does not change much and cracks will not occur.
If necessary, you can call me in my personal information. Can graphite packing be transported by air?
Yes, it depends on the product name you used for customs declaration.
If you are sending international express, it doesn’t matter the product name. Just find a less sensitive HS code and send it directly. How much temperature and pressure can graphite packing withstand, high pressure and high temperature resistant graphite packing
How much temperature and pressure can graphite packing withstand, high pressure and high temperature resistant graphite packing
Acetic acid and hydrogen oxidation The sodium reaction is an acid-base neutralization reaction, producing sodium acetate and water.
The reaction equation is:
CH3COOH+NaOH===CH3COONa+H2O
Sodium acetate is also known as sodium acetate
Colorless and odorless The crystals can be weathered in the air and are flammable. Easily soluble in water, slightly soluble in ethanol, insoluble in ether.
Loss of crystal water at 123°C. But usually the wet method has an acetic acid taste. Hydrolysis occurs in water. I bought graphite packing. Is there anyone who can buy it?
Graphite packing
What are the specific specifications?
Yes, you can call me in my profile! What are the differences between expanded graphite packing and flexible graphite packing?
The process characteristics of graphite packing are mainly determined by its crystalline form. Graphite minerals with different crystal forms have different industrial values ??and uses.
