[0037] In actual use, seamless steel pipes are widely used in the fields of petroleum, chemical industry, aerospace, etc. In the production process, in order to ensure the quality and safety performance of the product, it is necessary to test the pressure resistance of the seamless steel pipe. The pressure detection machine body 1 is often used for detection. The steel pipe is placed on the detection table, and then the button on the pressure detection machine body 1 is operated to drive the internal electrical appliances to run, so as to perform pressure detection on the seamless steel pipe.
