Railway E-Clips: Technical Data Sheet
| Aspect | Description & Details |
|---|---|
| Product Name | Railway E-Clip (Commonly known as: Spring Clip, Rail Clip, Type I Clip) |
| Primary Function | To elastically fasten the rail to the baseplate on sleepers/ties, maintaining track gauge and restraining rail movement under dynamic loads. |
| Key Features | - High Elastic Holding Force: Provides constant toe-load to secure the rail. - Vibration Damping: Absorbs dynamic forces, protecting the track structure. - Electrical Insulation: When used with nylon insulators, prevents current flow for signaling systems. - Fatigue Resistance: Designed for long service life under repeated stress. |
| Material | High-carbon, high-yield strength spring steel (e.g., 60Si2Mn, SUP10, SAE 1070). |
| Manufacturing Process | 1. Cold/Hot Forming: Wire is bent into the "E" profile. 2. Heat Treatment: Quenching & Tempering for high elasticity and strength. 3. Surface Treatment: Phosphating (grey) or Epoxy-Polyester Powder Coating (e.g., green, blue) for corrosion resistance. |
