Characteristics and Application of Pure Graphite Braided Valve Packing with Carbon

Pure graphite valve braided packing (with carbon) is mainly made of high-purity graphite filaments and carbon fibers. Graphite has excellent high temperature resistance and chemical stability, and can maintain good sealing effect under extreme working conditions. The addition of carbon fibers further enhances the compressive strength and wear resistance of the packing, and improves its reliability in long-term use.

The braided structure design makes the packing have good flexibility and sealing, and can adapt to valves of various shapes and sizes to ensure the sealing effect. Its appearance is usually a fine woven mesh structure, which can effectively prevent medium leakage.

Characteristics of pure graphite valve braided packing (with carbon)
High temperature resistance: Graphite has excellent high temperature resistance and can withstand temperatures up to 500℃ or even higher, which is suitable for sealing needs in high temperature environments.

Corrosion resistance: Graphite has strong corrosion resistance to most chemical media such as acids, alkalis, and salts. The addition of carbon fibers enables it to maintain stable performance in media with strong chemical reactivity.

Wear resistance: The addition of braided structure and carbon fiber improves the wear resistance of the packing and extends its service life.

Good sealing: The layered structure of graphite enables it to fit tightly to the sealing surface during valve operation to prevent medium leakage.

Pressure resistance: The braided structure containing carbon fiber increases the compressive strength of the packing, ensuring that it can still maintain a good sealing effect under high pressure.

Application of pure graphite valve braided packing (with carbon)
Pure graphite valve braided packing (with carbon) is widely used in various industrial fields, especially in high temperature, high pressure and corrosive medium environments, and plays an irreplaceable role. The main application scenarios include:

Chemical industry: In the chemical reaction process, high temperature and corrosion resistant sealing materials are often required, and graphite packing can effectively prevent chemical leakage.

Oil and gas industry: The extraction, transportation and processing of oil and natural gas often involve high pressure, corrosive gases or liquids, and graphite braided packing can provide reliable sealing solutions.

Power industry: In the boiler and pipeline systems of power plants, high temperature and high pressure are common working conditions, and the high temperature resistance of graphite packing makes it an ideal choice.

Food and pharmaceutical industry: In the process of conveying steam, acid and alkali solutions, pure graphite packing can ensure leak-free sealing and meet strict hygiene requirements.

Advantages of pure graphite valve braided packing (with carbon)

Long life: Due to its high temperature resistance, corrosion resistance and wear resistance, graphite braided packing has a long service life and can maintain stable sealing performance even under extreme working conditions.

Low friction: Graphite is self-lubricating, which means that during valve operation, the friction coefficient between the packing and the valve stem is low, which helps to reduce the operating force of the valve.

Easy to install and maintain: The braided structure makes the packing easy to install and replace, and due to its flexibility, it can adapt to valves of different sizes, reducing the complexity of maintenance.

Environmental protection: Graphite packing does not contain harmful chemicals, is environmentally friendly, and does not release harmful gases during use.

Installation and maintenance precautions
Preparation before installation: Before installation, the valve and packing cavity need to be cleaned to ensure that there are no impurities affecting the sealing effect.

Reasonable compression: During installation, pay attention to the degree of packing compression. Excessive compression may cause packing damage, and too loose will cause leakage.

Regular inspection: During long-term use, the sealing effect of the packing needs to be checked regularly. If leakage or severe wear of the packing is found, it should be replaced in time.

Avoid excessive temperature and pressure: Although graphite packing is resistant to high temperature and pressure, long-term exposure under extreme conditions may still cause the performance of the packing to deteriorate, so overload operation should be avoided.
