How to maintain E-type rail clip fasteners in low-temperature environments?
Maintaining E-type rail clips in low temps involves using low-temperature resistant materials, applying corrosion-proof coatings, ensuring correct installation gaps (around 3/8" or 10-12mm), performing regular visual/feeler gauge inspections, avoiding repetitive disassembly, and using specialized cold-weather lubricants, all to combat embrittlement, fatigue, and corrosion that cold exacerbates, keeping the self-tensioning system functional.
Material Selection & Preparation
- Material Choice: Select clips made from specific steel grades designed for low-temperature service to prevent brittleness and fatigue failure.
- Corrosion Protection: Apply specialized corrosion-resistant coatings (like galvanizing or specific paints) to protect against moisture and salt, which freeze and accelerate damage.
Key Considerations for Cold Weather
- Fatigue: Cold temperatures increase the risk of fatigue crack propagation, making proper installation and material quality critical.
- Self-Tensioning: The Pandrol e-clip relies on its springiness; cold can affect this elasticity if damaged or improperly installed.
Raw Material for Elastic Rail Clip
Elastic rail clips are made of high quality spring steel bar. These steels are generally low-alloy Manganese, medium-carbon steel or high-carbon steel with a very high yield strength. Spring steel has excellent comprehensive performance like mechanical properties, performance by the bullet-proof, fatigue, hardenability, physical and chemical properties. The raw materials of elastic railroad clip mostly include 55 Si7, 60 Si7, 65 Si7, 55 Si Cr7, 60Si2MnA, 60Si2CrA, 55Si2Mn, and 38Si7 grade of spring steel.
