What is the service life of Rubber Rail Pads?
The service life of rubber rail pads is typically between 8 and 25 years, but this can vary based on material quality, environmental conditions, and train traffic intensity. High-quality pads can last 8 to 25 years, while factors like extreme weather, heavy use, and maintenance practices can significantly impact their longevity.
Average lifespan: High-quality pads often last between 8 and 25 years.
| Rubber Rail Pad | ||
| Technical Parameter | Unit | Value |
| Stiffness | KN | 90-130 |
| Hardness Shore A | ℃ | 72-80 degree |
| Electronic Resistance | Ω | ≥ 106 |
| Tensile Strength before Aging | Mpa | ≥12.5 |
| Elongation before Aging | % | ≥250 |
Factors that affect lifespan:
- Environmental conditions: Exposure to extreme weather can shorten the service life.
- Traffic intensity: High-frequency train traffic puts more stress on the pads.
- Maintenance: Regular monitoring and timely replacement are crucial for maximizing longevity.
- Degradation: Over time, pads can degrade due to factors like oxidation and hydrolysis.
- Lifespan variation: The specific material and design can lead to significant differences in lifespan, with some specialized pads potentially lasting longer or shorter than others.
Rail pads classifications:
Rail pads for E-type rail fastening systems
Rail rubber pads used for E-type rail fastening systems are with the similar functions of the rail insulators to insulate the rail above it from the tie sleepers lied below it, for effective protection against vibration and structure-borne noise as well. The rail pad works together with e-clips, rail insulators/insulated gauge blocks and rail shoulders/embedded parts to form a whole set of E-type rail fastening system.
Rail pads for SKL rail fastening systems
A rail pad in a SKL rail fastening system is a small but crucial fastener part, working together with SKL clips, screw spikes, plastic dowels, guide plates and so on. The elastic rail pads we produce possess a defined stiffness and demonstrably increase the elasticity of the track superstructure. With a higher level of elasticity, it contributes towards quiet running of the rolling stock, to meet today's acoustic requirements on railway lines.
