E-type rail clip can provide durable alignment which can protect the steel rail and the fastenings from high pressure. The materials of e clip is spring steel which make e clip of high strength. There are many types of e clip: E1609, E1809, E1817, E2007, E2009, E2055, etc.
What is tensile strength of E rail elastic clip?
The tensile strength of an E-rail elastic clip varies by material (like 60Si2Cr spring steel) but typically falls in the high range, often around 1200 MPa (yield) to 1450 MPa (ultimate), designed to handle significant dynamic loads and fatigue, with some materials reaching up to 1450 MPa or more to ensure high fatigue life and prevent plastic deformation under service conditions.
E-clips function by providing clamping force (toe load) to secure rails, and their high tensile strength ensures they can withstand repeated stresses from passing trains without breaking or losing elasticity, making fatigue life a critical factor.
How does the e-railway clip protect the rails and sleepers?
E-railway clips (elastic clips) protect rails and sleepers by providing a strong, spring-loaded clamp that prevents rail movement, absorbs vibrations, controls thermal expansion, and ensures consistent gauge, reducing wear and tear, preventing derailments, and minimizing maintenance by creating a secure, self-tensioning connection between the rail and sleeper.
Protection for the Rail
- Prevents Movement: The clips grip the rail, stopping it from shifting horizontally (creep) or vertically, which maintains the correct distance (gauge) between rails, crucial for safety.
- Manages Thermal Forces: They absorb the forces from rail expansion and contraction due to temperature changes, preventing buckling or pulling apart.
- Absorbs Shock: The spring steel design absorbs impact energy and vibrations from passing trains, reducing stress and fatigue on the rail.
Protection for the Sleeper (Tie)
- Spreads Load: By clamping the rail to a baseplate, the clip helps distribute the immense load from the train over a larger area of the sleeper.
- Reduces Wear: The elastic cushion and secure fastening reduce friction and impact, preventing the sleeper from being damaged or worn down by the rail.
- Minimizes Maintenance: Their self-tensioning nature means they provide consistent clamping force without needing frequent retightening, reducing labor and costs.
