In rail track system, railway fish plates are important components to joint two steel rails together. In a real world application, there are three commonly used types of railway fish plates:
- Bolted joints
- Compromise joints
- Insulated joints
For railway fish plate, the bolted joints are usually used to join steel rails together before they are welded. As to joining two steel rails with differing sections, the compromise joints are mostly used. And the insulated rail joints are always used as the bonded or non-bonded joints.
Although the performances of these three types of rail joints are not the same, they still have many similar features:
Bolts and bars are all used and a discontinuity is created on the running surface of the rail track.The discontinuity can accelerate track degradation around the rail joints while trains are running.
Insulated railway fish plates
In common sense, railway fish plates or rail joints are metal bars with conductivity. While in order to make the electric insulativity needs of steel rails, insulated railway fish plates are also widely used in today's railroad construction as a new rail technology.
The insulated railway fish plates are made of thermosetting materials, with the properties of rustproof, anti-erosion, ultraviolet–proof, non-conductive and non-magnetic. These features make the insulated rail joints cannot be reprocessed and are therefore free from being stolen.
GNEE RAIL not only manufactures fishplates in various standard and custom specifications but also supplies matching fish bolts, spring washers, and flat washers. Additionally, we provide a wide range of railway fasteners, including rail clips (such as SKL, Nabla, E Clip, Fast Clip, and KPO types), screw spikes, dog spikes, gauge rods, rail pads, rail braces, rail clamps, and insulated gauge blocks etc. If you require more detailed information on railway fastener products, please contact us.
