Railway sleepers, also called railroad ties, railway crossties, or railway ties, are important railway components of the rail industry. Generally, the rail sleeper is always laying between two rail tracks to keep the correct space of the gauge.
Synthetic sleeper, also known as a composite sleeper, made of a composite material sheet produced by a foam extrusion process with continuous glass fiber as a reinforcing material(Fiber-reinforced Foamed Urethane), polyurethane as a supplemented with additives. It has higher strength and widely used as a structural material, besides, it is light in weight, insulating and resistant to aging, heat-insulating, chemical-resistant.China recently released the FFU sleeper performance standard(CJ/T 399 - 2012).
Anyang Railway Equipment Co., Ltd(AT) is a professional manufacturer of Composite Sleepers, compared with timber sleeper and steel sleeper, which are ideal for ballasted railway tracks, which have better damping and less wear.The productivity of synthetic sleeper in Anyang Railway Equipment Co., Ltd(AT) is 10,000 Pcs/month, our products have occupied a fast 70% market share in mainland China.The synthetic sleepers produced by Anyang Railway Equipment Co., Ltd(AT) have been used widely on all types of rail transport systems, particularly on switches, turnouts, bridges/viaducts, and other projects in high-speed and metro railway construction.
The shape of the composite sleeper is similar to that of an ordinary timber sleeper. The construction and installation process of composite sleepers is simple, and the composite railway sleepers can be sawed, planed, nailed, screwed, and glued with ordinary woodworking tools. The composite railway sleepers have a low thermal expansion coefficient and thermal conductivity, high anti-seismic, compressive, tensile, and flexural strength.
Composite sleepers can maintain good electrical insulation and stability even in long-term adverse weather conditions. The composite railway sleeper has better processing performance than the concrete sleeper. It is light in weight and can be processed into any length. It is not necessary to customize the mold for each length. After repairing the nail hole on the composite sleeper. It can be used again with long service life.Â
Technical Features of Railway synthetic sleepers
From the above table, we can get the conclusion that China Synthetic sleepers Standard: CJ/T 399-2012 is almost the same as Japan Synthetic sleepers Standard JIS E1203, regarding the technical requirement on Screw spikes pullout strength, CJ/T 399-2012 is higher than JIS E1203. From the above table, we can get the conclusion that the synthetic sleepers produced by Anyang Railway Equipment Co., Ltd fully comply with CJ/T 399-2012, and the test values are better than the required value shown in CJ/T 399-2012.
