This human eye recognition method has large errors, which greatly reduces the accuracy of the detection. In addition, the traditional pressure resistance testing equipment can only be used for the detection of a single model of steel pipes and has poor adaptability. Therefore, we propose a steel pipe pressure resistance testing equipment and a testing method to solve the above problems. Summary of the invention
