Railroad Spike Selection
When replacing a spike on a track and the anchoring spike needs changing, consider using a spike made of alloy material or treated with carbonitriding. Alternatively, choose a spike with an anti-corrosion sleeve between the threaded portions to prevent corrosion effectively.
Non-Sulfur Anchoring Materials
In China, sulfur anchoring agents are commonly used for railway screw spikes, but they can lead to severe corrosion. To address this, environmentally-friendly alternatives like water-hardening cementitious material (e.g., pure silicate 525 white cement) and corundum as a water-soluble anchoring agent are recommended.
Coating Long-Term Anti-Corrosion Grease
Due to exposure to various environmental conditions, spikes may require long-term protection. Special anti-corrosion long-life grease is recommended, providing water resistance, oxidation resistance, corrosion resistance, lubrication, adhesion, high-temperature resistance, and easy coating. This helps delay corrosion development and prolongs spike service life.
Standard Anchoring Operation
Strictly adhere to national standards for all anchoring operations. Refuse any informal or abnormal practices to ensure the proper and safe anchoring of spikes.
