GOST 1P-65 P65 rail joint fishplate

GOST 1P-65 P65 rail joint fishplate

GOST 1P-65 is a standard for lining used in the assembly of P65 rail joints with fishplates. The standard specifies the requirements for the manufacturing, dimensions, and mechanical properties of the lining material.

The lining material is typically made of high-quality carbon steel or alloy steel and is designed to be installed between the rail ends and the fishplates to ensure a secure and stable joint. The lining helps to distribute the load evenly across the rail joint, reduce wear and tear on the rails and fishplates, and prevent movement or displacement of the joint under heavy loads and dynamic forces.

According to GOST 1P-65, the lining for P65 rail joints with fishplates has the following specifications:

– Dimensions: The lining is typically rectangular in shape and has specific dimensions that match the profile of the P65 rail and the size of the fishplates.
– Material: The lining is made of high-quality carbon steel or alloy steel with a specific chemical composition that includes carbon, manganese, silicon, phosphorus, sulfur, and other elements in certain proportions.
– Mechanical properties: The lining must meet specific mechanical properties, including yield strength, ultimate tensile strength, hardness, and impact toughness, to ensure its durability and performance under heavy loads and harsh operating conditions.

The GOST 1P-65 standard also specifies testing methods and acceptance criteria for the lining material, including non-destructive testing techniques such as ultrasonic testing and magnetic particle inspection, to ensure its quality and safety.

Overall, GOST 1P-65 P65 rail joint fishplate is an essential component of P65 rail joints with fishplates, providing a secure and reliable connection between the rail ends and ensuring the safe and efficient operation of railway systems. It is widely used in mainline railways, industrial tracks, and metro systems where robust and durable track infrastructure is critical to supporting heavy traffic and maintaining operational efficiency.

1P-65 lining is 6 holes fishplate for P-65 rail joint, the length is 1000mm, unit weight is 29 kg/pc;
