Rail elastic clip is one of the popular fastening parts to keep rail track fixed on rail sleepers(wooden sleeper and concrete sleeper). Rail clamps are also used in some rail fastening systems.
GNEE RAIL railway supplies elastic rail clips(skl railway clip,kpo rail clamp,nabla railroad clip,e type rail elastic clip,etc) with high precision, high tensile strength and corrosion resistance, which are used widely in railway projects all over the world.Our rail clip product is ideal for rail track assembly for advantages of easy fitment while track laying; economical maintenance; long durability and lifespan; fast replacement.
The performance variations of railway elastic clips under different temperatures primarily manifest in clamping force, stiffness, and fatigue properties, as detailed below:
1. Low-Temperature Environments
Clamping force reduction: For every 10°C temperature decrease, fastener resistance declines by approximately 5%~10%.
Stiffness increase: Lower temperatures elevate material elastic modulus, increasing clip stiffness and potentially amplifying impact forces during train passage.
Fatigue performance degradation: Low temperatures may accelerate internal defect propagation, shortening clip fatigue life.
2. High-Temperature Environments
Clamping force attenuation: Elevated temperatures reduce spring steel elasticity, potentially decreasing clamping force by 10%~15%, necessitating periodic nut retightening.
Creep risk escalation: Prolonged high temperatures may induce plastic deformation, compromising gauge stability.
Material aging: Chronic heat exposure accelerates rubber baseplate degradation, indirectly impairing clip damping performance.
3. Extreme Temperature Performance
Below -50°C: Brittle fracture may occur in standard clips, requiring low-temperature steel or specialized heat treatment for performance enhancement.
Above +70°C: Non-metallic components risk softening failure, mandating heat-resistant materials or metal-rubber composite structures.
