The importance of corrosion prevention of railway bolts
Rail bolts, also known as track bolts, railway bolts, railroad bolts and rail joint bolts. Railway bolts is a kind of rail fasteners and play a vital role in railway construction. It can effectively enhance their lifespan and stability by the applying of appropriate corrosion prevention measures, ensuring the safety and reliable operation of railway tracks.
Common methods for corrosion prevention of rail bolts
GNEE rail introduces some common corrosion prevention methods for rail bolts.
- Zinc Coating
Galvanization is a widely used anti-corrosion treatment for the surface of fasteners. It involves applying a solid zinc powder metallurgical diffusion coating. Its uniformity allows for better dispersion in threads and blind holes, without causing significant environmental pollution during the manufacturing process.
- Galvanizing
Galvanizing is another commonly used method for rust prevention on the surface of railway bolts. To maintain consistent bolt pre-tension, a lubricant can be applied after galvanization to increase the bolt's torque.
- Blackening with Oil Coating
Blackening, also known as black oxide coating, is a material protection technique where steel is heated in the air or immersed directly in a concentrated oxidizing solution to produce an extremely thin oxide film on the surface. The process is often accompanied by oil coating to create a barrier against air and reduce the chances of substrate oxidation.
In conclusion
Applying corrosion prevention measures is vital for prolonging the lifespan of railway bolts, improving their corrosion resistance, and ensuring the safety and stability of railway tracks.
