Method, device and equipment for detecting sealing performance of oil pipe joint

The embodiment of the invention provides a method, a device and equipment for detecting the sealing performance of an oil pipe joint. The method comprises the steps: acquiring a sound signal of each measuring point on a front sealing surface and a rear sealing surface of an upper buckle of the oil pipe joint, wherein the sound signals are collected by an ultrasonic phased array probe; acquiring a magnetic signal of each measuring point on the outer walls of a front coupling and a rear coupling of the upper buckle of the oil pipe joint, wherein the magnetic signal is acquired by a magnetic memory probe; obtaining contact stress distribution information of the sealing surfaces of the oil pipe joint according to the sound signal of each measuring point on the front sealing surface and the rear sealing surface of the upper buckle of the oil pipe joint; acquiring stress distribution information of the threaded section of the oil pipe joint according to the magnetic signal of each measuring point on the outer walls
