Product Introducing:
Pure Graphite Valves Braided Gland Packing with Carbon Fibres is a packing rope made of high-purity expanded graphite and reinforced carbon fibers. Graphite is resistant to high temperatures, corrosion and self-lubricating, while carbon fibers further enhance its strength and pressure resistance. This combination of materials is particularly suitable for harsh industrial environments and can maintain a stable sealing effect for a long time under extreme conditions.
Main parameters:
Material composition: high purity expanded graphite and carbon fiber
Temperature range: -200°C to +650°C (up to +850°C in steam or inert gas environment)
Pressure range:
Up to 200 bar in valve applications
Up to 100 bar in pump applications
pH range: pH 0-14 (suitable for most acids, alkalis and organic chemicals)
Linear speed: up to 20 m/s in the pump
Density: typically 1.3-1.6 g/cm³
Thermal conductivity: Graphite has a high thermal conductivity, usually 5-10 W/mK
Tensile strength: reinforced with carbon fiber, high tensile strength
Product features: High temperature stability: Expanded graphite has excellent high temperature stability and can remain unchanged and decompose in extremely high temperature environments.
Chemical corrosion resistance: The product has good chemical resistance and is suitable for almost all chemical media (except strong oxidants such as nitric acid, chlorine, etc.).
Self-lubricating property: Expanded graphite has strong self-lubricating property, which reduces the wear of equipment and increases the life of equipment.
High pressure bearing capacity: The enhanced carbon fiber structure enables the filler to maintain good sealing performance under high pressure.
Wear resistance: Carbon fiber provides additional mechanical strength and reduces the wear of the filler, especially in dynamic sealing environments.
Low friction coefficient: Self-lubricating properties and low friction coefficient reduce energy consumption and improve the operating efficiency of the equipment.
Application scenarios:
Valve seals: Suitable for various industrial valves, especially in high temperature, high pressure and highly corrosive environments. The product can effectively prevent gas or liquid leakage and ensure the safety and stability of the equipment.
Pump seals: In dynamic sealing occasions (such as centrifugal pumps and reciprocating pumps), it can effectively reduce friction and wear and extend the service life of the equipment.
Chemical industry: Due to its excellent corrosion resistance, the filler is widely used in corrosive fluids and gas pipeline systems in the chemical industry.
Oil and gas industry: Suitable for sealing under extreme conditions, can cope with high temperature and high pressure conditions, and reduce downtime and maintenance costs.
Power plants and nuclear power plants: The high thermal conductivity and high temperature resistance of expanded graphite make it an ideal sealing material for steam systems, condensers, boilers and other equipment in power plants.
Metallurgical Industry: In steel smelting and nonferrous metal smelting, the products are used for sealing equipment that is resistant to high temperatures and corrosion environments.

READ MOREIn the rapidly developing industrial field, sealing technology is a key link to ensure the stable operation of equipment and prevent medium leakage. Its importance is self-evident. Since its establishment in 2004, the sealing technology company located in Xingyuan Road, Yuanzhu Industrial Park, Taixing City, Jiangsu Province has become a leader in the field of domestic sealing technology with its outstanding R&D strength, strict quality management system and forward-looking market layout. Among them, the pure graphite stuffing box, as the company's star product, has won wide acclaim in the market for its excellent sealing performance, environmental protection characteristics and wide application fields.
As an important part of high-end sealing solutions, the pure graphite stuffing box is made of high-purity graphite materials. Graphite, one of the softest minerals in nature, has shown extraordinary hard power in the field of sealing. Its excellent high temperature resistance, corrosion resistance, self-lubrication and good compression rebound performance enable the pure graphite stuffing box to maintain a stable sealing effect under extreme working conditions, effectively extending the service life of the equipment and reducing maintenance costs.
Relying on a strong scientific research team and advanced production equipment, the company continuously optimizes the formula and manufacturing process of the pure graphite stuffing box to ensure that its product performance reaches the international advanced level. By precisely controlling the particle size distribution of graphite and adding appropriate amounts of reinforcing agents and lubricants, the stuffing box can maintain high sealing performance while also having good anti-scouring and anti-wear capabilities, and can adapt to the sealing needs under various complex working conditions.
In the current context of global advocacy of green development, the company actively responds to national environmental protection policies and is committed to developing environmentally friendly sealing products. Pure graphite stuffing boxes, as asbestos-free and non-toxic environmentally friendly sealing materials, not only meet international environmental standards, but also greatly reduce potential harm to the environment and human body. This move not only reflects the company's sense of social responsibility, but also sets an example for promoting the green transformation of the entire sealing industry.
Pure graphite stuffing boxes have been widely used in many industries such as shipping, power, steel, chemical industry, and machinery due to their excellent performance and wide applicability.
