Core advantages
- Integrated Lubrication: Unlike surface-coated seals, our ptfe graphite packing ensures the lubricant is present throughout the entire cross-section.
- Thermal Management: The high carbon content in our graphite packing material prevents heat buildup, protecting the pump shaft from thermal damage.
- Elasticity & Recovery: Specifically braided to maintain a tight graphite packing gland seal even under pressure fluctuations.
Typical Applications
- 1. Power generation and heat exchange systems
- 2. Petrochemical and refinery equipment
- 3. Steam and condensate lines
- 4. High-temperature gas and fluid sealing
- 5.Industrial furnaces and mechanical shaft sealing
Available in multiple compositions—including cotton fiber reinforced graphite, glass fiber reinforced graphite, and Graphite PTFE variants—this range offers tailored solutions for different operating environments. Every material is braided and treated for optimum compression recovery, leakage control, and thermal stability under continuous service.
FAQ
Q1: What is the benefit of using ptfe graphite packing over pure white PTFE?
A: Pure PTFE has poor thermal conductivity. By using braided graphite packing, the heat generated by friction is dissipated much faster, allowing the equipment to run at higher speeds without burning the graphite packing material.
Q2: Can this graphite packing gland seal handle aggressive acids?
A: Absolutely. Our ptfe graphite packing is chemically inert and resistant to almost all media within the PH 0-14 range, making it ideal for the chemical and paper industries.
