GOST 2P-65 lining P65 rail joint

GOST 2P-65 lining P65 rail joint is another standard for lining used in the assembly of P65 rail joints. This standard specifies the requirements for the manufacturing, dimensions, and mechanical properties of the lining material used in P65 rail joints.

GOST 2P-65 lining P65 rail joint is similar to the GOST 1P-65 lining in that it 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 2P-65, the lining for P65 rail joints has the following specifications:

– Ölçülər: 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 2P-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 2P-65 lining P65 rail joint is an important component of P65 rail joints, 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. While the exact specifications of GOST 2P-65 may differ slightly from those of GOST 1P-65, both standards are designed to provide high-quality lining materials for P65 rail joints that meet strict performance and safety requirements.
