How Much Do You Know about Railway Joints And Insulated Railway Joints

Railway joints, commonly known as railway fish plates, is a railway fastener that used to connect two pieces of steel rails. Depending on usages, railway joints can be divided into light railway joint, heavy railway joint and super heavy railway joint. On the process of railroad construction, the use of railway joints can save working hours than rail welding. And with the feature of being easy to install, railway joints are widely used in railroad construction collocated with railway fish bolts. There are holes in the middle of railway joints, four holes railway joints and six holes railway joints are the most two common types. Along the horizontal axis of the screw holes both on upper side and lower side, there are working faces contact to the steel rails. On the back of the working face, there is a transition section higher than the working face. The transition section along the railway joint length direction to form middle low and ends high as the bridge arch. For its simple structure, bridge type railway joint can reduce the wheel impact on steel rails, increase the continuity of rail longitudinal deformation at joint, and improve the smoothness when train passing. Light railway joint is also called railway splint or railway fish plate, and heavy railway joint is also called heavy rail angle joint splint. Insulated railway joints are made of insulated materials. Insulated rail joint is made of a new type of high strength composite. On railway system, insulated railway joints have many features, such as corrosion resistance, rust protection, ultraviolet-proof, non-conducting and non-magnetic. And for this type of insulated materials can not be reworking, insulated railway joints are not afraid of theft. Common railway joints have four holes or six holes. According to the materials, railway joints can be divided into spheroidal graphite cast iron, Q235 rolling steel and forging steel. In general, railway joints are often made of medium carbon steel and high-carbon steel. As a professional manufacturer of railway joints, we can also produce composite material type railway joints, cast iron railway joints and cast steel railway joints. As a professional railway joint manufacturer, AGICO Rail can manufacture various standards of railway joints according to customers’ requirements, orders welcome!
