Gland packing JIC 3074 CR
is a lubricated carbon fiber packing designed for high-temperature and high-pressure sealing applications in pumps and valves.
Key Features and Specifications
- Material Composition: It is made from carbon fiber yarns that are lattice-braided into a square cross-section packing. These yarns are then impregnated with a special heat-resistant lubricant and treated on the surface with graphite.
- "CR" Designation: The "CR" in the name typically stands for Carbon Fiber (and often implies a specific lubrication/graphite treatment process by the manufacturer, like "3 Star" brand).
- Properties:
- Excellent heat resistance.
- Good chemical resistance, suitable for a pH range of 2 to 12.
- Superior thermal conductivity and heat radiation.
- Self-lubricating properties for long life and reduced shaft wear.
- Performance Parameters:
- Max Temperature: up to 450°C (840°F).
- Max Pressure: up to 100 kgf/cm² (approx. 1422 PSI or 98 bar).
- Applications:
- Widely used in high-temperature, medium-to-high-pressure environments in heavy industries.
- Suitable for a variety of valves (globe, gate, ball) and pumps (reciprocating, centrifugal, screw).
- Often used in combination with other packings, such as JIC 4101, for optimal performance.
This packing material is designed as a reliable sealing solution for demanding industrial environments where durability and resistance to extreme conditions are required.
