Chinese standard P50 has a little different than GOST R50, but the different is less than allowable, most people would like to use P50 instead of R50. Please refer the drawing:

GOST 7174-75 P50 50kg steel rail is used in railway tracks. The GOST (ГОСТ) standards are technical standards developed by the Russian government and used in several countries, including Russia, Ukraine, and Belarus.

The P50 designation refers to the weight per meter of the rail, indicating its load-bearing capacity and strength. In this case, the P50 rail weighs approximately 50 kilograms per meter. It is commonly used in heavy-duty railway applications where high loads and heavy traffic volumes are expected.

GOST 7174-75 P50 50kg steel rail features a unique profile designed to provide stability and support to railway operations. It has a flat top surface with inclined sides and a broad base, allowing for smooth movement of trains while distributing weight effectively and minimizing wear and fatigue.

The rail’s construction is made from high-quality steel that undergoes stringent manufacturing processes to meet the specified requirements of the GOST 7174-75 standard. The rail is engineered to withstand heavy loads and dynamic forces associated with railway operations.

Proper installation and maintenance of GOST 7174-75 P50 50kg steel rail are critical for ensuring safe and reliable railway operations. The rail must be securely fastened to the track bed using appropriate rail clips, pads, and fasteners to maintain proper alignment and stability. Regular inspections are also necessary to check for any signs of wear, deformation, or misalignment.

The GOST 7174-75 P50 steel rail offers excellent dimensional accuracy, straightness, and uniformity. These qualities contribute to the smooth movement of trains along the rail, reducing noise and vibration. Additionally, the rail’s sturdy construction and precise design provide long-lasting durability and resistance to wear, ensuring reliable performance even under demanding operational conditions.

In summary, GOST 7174-75 P50 50kg steel rail is a robust and reliable rail profile designed specifically for heavy-duty railway applications. By adhering to the GOST 7174-75 standard, this rail ensures safe and efficient transportation of heavy loads in various railway settings. It serves as a critical component in railway systems that require stability, strength, and durability to handle the challenges of heavy railway operations.
