Products Description
Rails have different specifications and sizes. The selection of rails of different specifications is determined by factors such as train speed, transportation load, and line geological conditions. The cross-sectional design of the rails will also affect their bending strength and fatigue life. The promotion of standardized specifications will help the unified construction and maintenance management of the rail system.
Under the high-frequency operation and heavy load of trains, the fatigue life of railway rails is closely related to the quality of maintenance. Under normal circumstances, the service life of a rail can reach 20 to 30 years, but in high-speed railways or heavy-load railways, the service life may be shortened to 10 to 15 years, so regular inspection and maintenance are required.
