FAQ Section 1
Q: What makes Asbestos Gland Packing suitable for high-temperature applications?
A: Asbestos Gland Packing maintains its structural integrity at temperatures up to 500°C due to the inherent heat-resistant properties of asbestos fibers. The material doesn't melt or degrade under extreme heat conditions, making it ideal for boiler systems, steam valves, and other high-temperature industrial applications.
| Size (mm) | Standard Length (m) | Weight (kg/m) |
|---|---|---|
| 3x3 | 10 | 0.12 |
| 5x5 | 10 | 0.30 |
| 6x6 | 10 | 0.45 |
| 10x10 | 5 | 1.20 |
Installation Guidelines
- Clean the stuffing box thoroughly before installation
- Measure and cut packing rings to exact length
- Stagger joints by 90° between layers
- Use proper compression tools
- Follow manufacturer's torque specifications
FAQ Section 2
Q: How often should Asbestos Gland Packing be replaced?
A: The replacement interval depends on operating conditions, but typically Asbestos Gland Packing lasts 6-18 months in normal service. Signs for replacement include excessive leakage (more than 40-60 drops per minute), increased friction, or visible wear. Regular maintenance checks are recommended every 3 months in high-pressure applications.

FAQ Section 3
Q: Are there any alternatives to Asbestos Gland Packing?
A: Yes, non-asbestos alternatives like graphite, PTFE, or aramid fiber packings are available for applications where asbestos is restricted. However, these may have different performance characteristics regarding temperature resistance, pressure capability, and chemical resistance. Our technical team can help select the most suitable material for your specific application requirements.
