[0002] During the production process of pipes, the pipe diameter is a key indicator to measure the quality of the pipes. Measuring the outer diameter of the pipe can not only monitor the diameter of the product to avoid producing out-of-tolerance products, but also monitor the defects with abnormal dimensions on the surface of the pipe, such as wear, inclusions, etc. The most common way to measure the diameter is to use a caliper. This method can only be used for random inspections on the production line, which is likely to cause large material losses and economic losses.
