GOST 2R-65 is a standard for lining used in the assembly of R65 rail joints with joint bars. 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 joint bars 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 joint bars, and prevent movement or displacement of the joint under heavy loads and dynamic forces.
According to GOST 2R-65, the lining for R65 rail joints with joint bars has the following specifications:
– Dimensions: The lining is typically rectangular in shape and has specific dimensions that match the profile of the R65 rail and the size of the joint bars.
– 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 2R-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.
