A steel pipe out-of-roundness prediction method of predicting out-of-roundness of a steel pipe after a pipe expanding step in a steel pipe manufacturing process including: an end bending step; a press bending step; and the pipe expanding step, the steel pipe out-of-roundness prediction method includes a step of predicting the out-of-roundness of the steel pipe after the pipe expanding step by using an out-of-roundness prediction model having been trained by machine learning, the out-of-roundness prediction model for which an input data is data including one operational parameter or two or more operational parameters selected from the operational parameters of the end bending step and one operational parameter or two or more operational parameters selected from the operational parameters of the press bending step, and an output data is steel pipe out-of-roundness information after the pipe expanding step.

The present invention provides an improved inner-supporting-type online roundness correcting device for a semifinished wheel, which comprises a machine frame, hydraulic cylinders, guide rails, servo motors and correcting wheels. When a bulge of the wheel is met, angles of left correcting wheels II are adjusted through a left servo motor, the left correcting wheels II are kept to be in contact with an inner rim of the wheel all the time and remain stationary in the position, and then, a left hydraulic cylinder enables a left correcting wheel Ito press the bulge of the wheel, so as to recover the roundness of the bulge; and when a depression of the wheel is met, right correcting wheels I are kept to be in contact with an outer rim of the wheel all the time and remain stationary in the position through a right hydraulic cylinder, the angle of a right correcting wheel II is adjusted through a right servo motor, and compressing hydraulic cylinders enable the right correcting wheel II to press the depression of the wheel, so as to recover the roundness of the depression.

A tool for repairing an out-of-round component such as a combustor body is disclosed. The tool includes a base including a first arcuate member; a second arcuate member; and a linear actuator coupling the second arcuate member to the base. The linear actuator moves the second arcuate member between a retracted position out of engagement with the out-of-round component and an extended position in which the first arcuate member and the second arcuate member engage an interior surface of the out-of-round component in an opposing relationship to force the out-of-round component into a more round state compared to an initial state of the out-of-round component. A related method is also disclosed.

A rub rail repair tool includes a tool engaging element disposed on one longitudinal side of a flange. A working element is disposed on the other longitudinal side of the flange. The working element is shaped to define a maximum diameter dimension and a minimum diameter dimension. The maximum diameter dimension is substantially equal to a distance between an undamaged rub rail affixed to a lateral edge of a truck bed frame. At least one tool engaging feature is formed in the tool engaging element. The tool engaging feature enables coupling of a torque arm to the tool engaging element to enable rotation thereof about a longitudinal axis thereof by applying force to the torque arm.
