Title:
PIPE PRESSURE RESISTANCE TESTING DEVICE AND TESTING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/267075
Kind Code:
A1
Abstract:
A pipe pressure resistance testing device and a testing method thereof. The pipe pressure resistance testing device comprises a device underframe (1), a cylinder body (8), a pipe (15) to be tested and a pipe deformation online measurement device; the cylinder body (8) is provided above the device underframe (1), and a roller (14) is provided on the position at the inner bottom surface of the cylinder body (8) close to a sealing end thereof; a flange inner supporting sleeve (5) is fixedly provided at an opening end of the cylinder body (8), said pipe (15) has one end provided on the roller (14) and the other end provided on the flange inner supporting sleeve (5), and said pipe (15) has one end provided with a plug (13) and the other end provided with a locking sleeve (4); the locking sleeve (4) is communicated with the pipe deformation online measurement device by means of a first guide pipe (3), and is used for external pressure resistance test and measurement of a pipe; both ends of said pipe (15) are sealed and blocked, and a U-shaped pipe (2) is provided, so that a flattening condition of said pipe (15) is accurately reflected by observing the increase and decrease of the liquid level in the U-shaped pipe (2); meanwhile, a camera (9) and a display (19) are further provided, so that the deformation of the pipe can be observed in real time. The device not only can determine the deformation of said pipe (15), but also can quantitatively test the amount of deformation of the pipe.
