A railway fishplate for P50 rail is a critical joint bar used to connect P50 (50 kg/m) rail sections, providing structural continuity and alignment for standard and heavy-haul railway tracks.
Rail Compatibility: Specifically designed for P50/R50 rail profiles, which stand 152 mm tall with a base width of 132 mm.
Weight: Standard fishplates for P50 rail typically weigh 6.8 kg per piece for 6-hole variants under common standards TB/T 2345-2008. Some variations for different industrial needs can range higher. Signum is able to customize P50 railway fishplates according to your drawing and requirements.
Material: Manufactured from high-strength carbon steel, such as 50#, 45#, or 50Mn.
Hole Configuration: Most commonly available in 6-hole patterns to ensure maximum joint rigidity, though 4-hole versions exist for lighter industrial applications.
Hole Dimensions: Typically features bolt holes of 30 mm in diameter to accommodate high-strength fish bolts.
GOST P51685-2022: The latest standard for Russian and Eurasian railway systems.
GB2585-2007: The Chinese national standard commonly used for international export.
TB/T 2345-2008: Technical requirement for joint bars used in standard railway systems.
Mainline Railways: Used for medium-weight national trunk lines and subways.
Industrial Use: Frequently found in mine car railway lines, industrial transportation corridors, and crane tracks.
Transit: Suitable for urban rail systems and medium-to-low-speed railway networks.
