Under some special environmental conditions, such as high temperature, high cold, humidity, corrosion and other areas, the performance of fastener system is severely challenged. SKL fastener system successfully copes with these complex environments through innovative design concepts and advanced material technology, showing strong adaptability and reliability.
In high temperature environment, such as railway projects in desert areas or near industrial high temperature places, fasteners made of ordinary materials are easily softened and deformed due to high temperature, resulting in decreased fastening performance. In response to this problem, SKL fastener system uses high temperature resistant materials to manufacture key components. For example, the tension clamp is made of high temperature alloy with a melting point of more than 1300℃. It can still maintain stable mechanical properties in a high temperature environment above 300℃, and will not soften or deform, ensuring that the fastening force is not affected. At the same time, other components such as screw spikes, track pads, etc. are also treated with high temperature resistance, so that they can work normally in high temperature environment and ensure the stability and safety of the track.
In high-altitude cold areas, such as Northeast and Northwest my country, and in high-altitude railway construction, low temperatures can make materials brittle and increase the risk of fastener breakage. The SKL fastener system performs low-temperature toughness treatment on metal parts such as screw spikes. Through a special heat treatment process, the internal structure of the material is improved to increase its toughness in low-temperature environments. After testing, the treated screw spikes can still maintain good mechanical properties at a low temperature of -40°C, and the tensile strength and elongation meet the design requirements, effectively avoiding fracture accidents caused by low-temperature embrittlement.
