This series of graphite gland packings is developed for demanding sealing environments requiring high thermal resistance, excellent chemical stability, and low friction performance. The base graphite material provides superior heat dissipation and chemical inertness, while reinforcement with cotton fiber, glass fiber, or metallic wire (stainless steel, Inconel, or copper) significantly enhances tensile strength and structural durability. Each braided graphite packing is optimized to withstand elevated temperatures, pressures, and aggressive media, making it suitable for use in pumps, valves, turbines, and reactors. Depending on the reinforcement type, the packings can handle both static and rotary operations with minimal wear and long service life.
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.
