Graphite packing - GR8748

Composition

- PAN graphite Inconel® discontinuous wire yarns
- Flexible graphite yarns
- Graphite Powder
- Passive Inhibitor of Corrosion

Characteristics

The graphite braid GR8748 is characterized by a particular structure, making it a high-performance and reliable product for demanding industrial applications. Made with expanded mineral graphite yarn at its core and continuous P.A.N. graphite yarn reinforced with discontinuous Inconel™ filaments on the corners, this packing offers superior resistance to high temperatures and corrosive conditions. Each yarn is impregnated with a compound of graphite powder and inorganic corrosion inhibitor, ensuring greater durability and reliability. Thanks to its composition, GR8748 is able to withstand thermal cycles and mechanical stresses without deformation or weight loss.

Applications

GR8748 is a highly versatile and reliable graphite packing, ideal for a variety of industrial applications. Its high resistance to high temperatures and mechanical stress makes it perfect for use on valves in steam, hydrocarbon, and petrochemical services, as well as on reciprocating pumps and agitators. However, it is important to remember that it is not suitable for applications with strong oxidizers and with exhaust gases or air above 450°C. Thanks to its elastic and mechanical properties, GR8748 ensures reliable and long-lasting sealing, minimizing the risk of leaks and malfunctions. So if you're looking for a reliable and durable solution for industrial applications, the graphite packing GR8748 is definitely the right choice.
