Rail clip, also known as elastic rail clip, is used for railroad sleepers to fix the rails on both sides. Rail clips are usually made of forged spring steel and manufactured by hot forging process.
E2055 rail clips belong to Pandrol rail clips. It is a kind of E-type rail clips.
What is the service life of the e2055 rail clip?
The E2055 rail clip's service life is generally specified by its fatigue life, lasting 3 to 5 million load cycles without breaking, depending on the specific diameter (e.g., Dia.18 is 3M cycles, Dia.20 is 5M cycles), with manufacturers often guaranteeing 5 million cycles under standard fatigue tests. While exact track replacement varies, these clips are engineered for high durability under repeated stress, with typical materials like 60Si2Cr offering resilience.
Key Factors in E2055 Clip Service Life:
- Fatigue Strength: The primary measure, typically 3-5 million cycles, meaning millions of train passes before failure.
- Material: Made from spring steels (like 60Si2Cr, 55SiMn) chosen for strength and elasticity.
| Material | 60Si2MnA | 60Si2CrA | 55Si2Mn | 38Si7 |
| Chemical composition(%) | C:0.56-0.64, Mn:0.60-0.90, Si:1.60-2.00, Cr:≤0.35, P:≤0.03, S:≤0.03 | C:0.56-0.64, Mn:0.40-0.70, Si:1.40-1.80,Cr:0.70-1.00 P:≤0.03, S:≤0.03 | C:0.52-0.60, Mn:0.60-0.90, Si:1.50-2.00,Cr:≤0.35 P:≤0.03, S:≤0.03 | C:0.35-0.42, Mn:0.50-0.80, Si:1.50-1.80, P:≤0.03, S:≤0.03 |
- Diameter: Larger diameters (like Ø20mm) often have higher cycle ratings than smaller ones (like Ø18mm).
- Hardness: Hardness (e.g., 42-48 HRC) is crucial for maintaining elasticity and preventing wear.
| Item | Diameter | Material | Weight | HRC Under pressure | Fatigue test |
|---|---|---|---|---|---|
| E2055 | ø20 | 60Si2MnA, 60Si2Cr, 55Si2Mn, 38Si7 | 0.80 kg | 44-48 | ≥950kg 5000000 times without breaking |
- Application: High-speed, heavy-haul, or curved track sections can induce more stress, potentially affecting longevity compared to low-traffic areas.
Elastic Rail Clips Manufacturing Process
Based on the process production, elastic rail clip manufacture process include following steps: raw material- shearing- heating- forming- hardening- tempering- inspection- packing.
Features of E 2055 rail clip
The E 2055 rail clip is designed to withstand the dynamic forces and vibrations experienced by railway tracks during train operations. Its robust construction helps to reduce track maintenance requirements, minimize rail movement and noise, and enhance overall track stability and safety.
Quick installation and removal： One notable feature of the E 2055 rail clip is its design, which allows for quick and efficient installation and removal.
- Robust construction ：The clip consists of a curved, U-shaped portion that clamps onto the base of the rail, holding it securely in place.
- Excellent clamping force： The clip is designed to exert a specific amount of pressure on the rail, ensuring a tight fit while allowing for necessary expansion and contraction due to temperature variations.
