IDEA #8JGF2E DEVICE FOR INSPECTING PIPES USING ULTRASOUND

Abstract not available for EP1423689 Abstract of corresponding document: US2004211261 The invention relates to a device for inspecting pipes using ultrasound, in particular for inspecting the end regions of a pipe. Said device comprises at least one ultrasonic inspection head (38) with an inspection tank (24), which a) has a receiving chamber (26) that is designed to receive a coupling fluid, in particular water (27), b) forms an axial passage through which a pipe (20) that is to he inspected can be transported along an inspection line (28) relative to the inspection tank (24) c) has sealing elements at the front and rear (34, 36), said elements being adapted to the external diameter of the pipe (20) that is to be inspected and delimiting the receiving chamber (26), and d) contains the inspection head(s) (38) in such a way that only coupling fluid is present between the inspection head (38) and the pipe (20) that is to be inspected. The device also comprises a cylindrical mandrel (22), whose external diameter is adapted to the external diameter of the pipe (20) to be inspected and which has a front seal (42) on its front face that forms a tight seal with a first front face of the pipe (20) to be inspected. The length of said mandrel is greater than the clearance between the two sealing elements (34, 36). https://app.acclaimip.com/pdf/VT-Pxu_M6SgtP4-jCszpJEanYBKVb0H_XPPXOlQ/EP1423689B1
