WebMay 18, 2024 · Ovality is most likely to occur in two situations: during the pipe joint fabrication process (arbitrary out-of-roundness) and from externally applied loads during and following the pipeline construction phase (symmetric ovality). This brief article only addresses symmetric ovality. Most industry codes provide guidance on the acceptable ... In JIS B0621-1984, the definition and expression of form and position deviation, roundness is defined as “the deviation from the geometric circle of a circular body.” The representation method is recorded as “when the roundness of a circular body (C) is sandwiched by two concentric geometric circles, the minimum … See more Roundness tolerance zone refers to the tolerance zone between two concentric circles of the same section. As shown in the figure, the extracted circumference should be limited … See more There are several methods for evaluating roundness, each with its own unique features and advantages. The method to use is typically selected based on the specific requirements … See more Micrometer: Roundness measuring instrument: Coordinate measuring machine: The space is limited, and you are welcome to leave a message and criticize the matters not covered.
