Do You Know The Standards For Railway Spikes

The railway spike standard refers to an iron or steel device used to fix the rails, which has certain shape and size standards to ensure a firm connection between the rails and the roadbed. Railway spike standards are usually formulated by national or regional railway management departments and must comply with the relevant regulations of the International Standards Organization.

The following is a reference to the standards for railway spikes:

1. Material requirements for spikes:

Spikes are usually made of high-quality carbon steel or alloy steel, with certain toughness and strength. The carbon content is controlled at 0.45%~0.75%, the silicon content is controlled at 0.15%~0.35%, the manganese content is controlled at 0.6%~1.1%, and the sulfur and phosphorus contents are controlled at a low level to ensure the strength and corrosion resistance of the spikes.

2. Appearance requirements for spikes:

Spikes should be cleaned, rust-removed, etc., the surface should be flat and smooth, without obvious scars and cracks, and the surface of the spikes should also be rust-proofed. Commonly used methods include hot-dip galvanizing and cold-dip galvanizing to improve the corrosion resistance of the spikes.

3. Geometric parameter requirements of railroad spikes:

The geometric parameters of railroad spikes include length, diameter, head shape, taper, etc. The length is usually 150mm~180mm, the diameter is usually 16mm~24mm, the head shape is usually hemispherical or cylindrical with round ribs, and the taper is usually 1:20~1:15. These parameters are designed and controlled to ensure a good connection between the railroad spike and the rail, and have a certain anti-slip ability.
