Rubber railroad tie pads are actually the shockproof pad used on railways, usually the abbreviation of rubber pad for railway track. Sleeper pads are key components of railway structures and are used between steel rails and concrete sleepers.
The main function of the rubber tie pad is to reduce the vibration and impact generated when the train passes, thereby protecting the railway foundation and sleepers. More importantly, the railway pad isolates the signal system and reduces noise (especially when used in the subway rail fastening system).
Since the rubber pads are always exposed to the atmosphere, they have higher requirements for natural aging, cold resistance, and heat resistance.
The rail pad is made of natural rubber, styrene butadiene rubber, HDPE, EVA, high-density polyethylene, polyethylene, etc., and it is not easy to deform or break at high or low temperatures. In addition, it also has the following advantages:
1. Strong vibration resistance, strong stability and wear resistance
2. Long service life, low maintenance and replacement cost
3. There are various types of rail pads, which are suitable for most rails and railway sleepers.
4. Good absorption of uneven contact surface between guide rail and bracket
Types of Railroad Tie Pads:
1. Rail pad for E-type rail fastening system
The rail rubber pad used in the E-rail fastening system has a similar function to the rail insulator, which can isolate the rail above it from the sleeper below it, effectively preventing vibration and structural noise. Rail pads, e-clips, rail insulators/insulating gauge blocks, and rail shoulders/inserts form a complete set of E-type rail fastening systems.
2. Rail pad for SKL rail fastening system
The rail pad in the SKL rail fastening system is a small but important fastener component that works with SKL clips, screws, plastic pins, tie plates, etc. The elastic track pads we produce have a certain rigidity and significantly increase the elasticity of the rail superstructure. It has higher elasticity and helps rolling stock to run quietly to meet the acoustic requirements of today's railway lines.
3. Rubber pads for concrete sleepers
|43kg/m ,50kg/m, 60kg/m, 75kg/m rail
|43-7-7, 43-10-7, 50-7-9, 50-10-9, 60-10-17, 60-12-17
|Should be stored in clean, ventilated place. Don’t put under direct sunlight, and keep away from heat sources and chemical reagents. Don’t touch oil, organic solvent and other chemicals.
4. High elastic groove EVA/HDPE/rubber rail pad
Our EVA/HDPE/rubber rail pads have high elasticity, suitable for UIC54, UIC60, BS80lbs, BS100lbs and other rail types and order sizes. According to the customer's requirements, the pads with or without grooves can be customized, and various possible designs are adopted.
