Description

INTEGRATED AUTOMAITC NON-DESTRUCTIVE TESTING SCANNER

The present invention can perform PAUT, TOFD, and MW inspection with one inspection scanner, and can be applied to butt fusion joints and electronic socket fusion joints, which are inspection bodies having different inspection areas and shapes.

Nondestructive testing is a method of inspecting the presence of abnormalities or defects inside or on the surface of a test object from the outside without destroying the test object. Non-destructive testing can effectively detect defects without affecting the material, shape, or function of a test object, so research on non-destructive testing devices is being actively conducted.

As a type of this non-destructive testing technique, microwave testing (hereinafter referred to as MW), which is a technique for inspecting the presence of defects by observing changes in electro-magnetic force on the surface and sub-surface discontinuities or internal discontinuities using microwaves, various Phased Array Ultrasonic Testing (PAUT), an inspection technique that provides two-dimensional images in real time, can be used to steer and focus the beam through the ultrasonic oscillation time delay of each vibrator by using a transducer arranged with individual vibrators. ), and Time Of Flight Diffraction (TOFD), which is a technique for measuring the height (depth) of defects generated in welds and structures such as pressure vessels and pipes using the diffraction and time of ultrasonic waves. .

Meanwhile, in the prior art, since the types of defects to be detected differ according to the types of non-destructive inspection techniques, each non-destructive inspection scanner is required for each type of inspection object and inspection technique. Accordingly, the operation of installing and dismantling each non-destructive inspection scanner is repeated, thereby reducing efficiency and convenience, and increasing inspection time.

In particular, when the inspection object is a pipe, when inspecting the fusion part where two pipes are connected, the inspection technique to be applied varies depending on the type or shape of the fusion part.

Butt fusion is a method of melting the cross-sections of two pipes and then welding the two pipes together. A pipe with butt fusion is shown in FIG. 1A . Butt fusion, MW, PAUT, and TOFD inspection is applicable. In addition, the electronic socket fusion (Electrosocket fusion) is a method in which two pipes are inserted into the electronic socket, and then heat is applied to the pipe with a hot wire inside the socket to melt and fuse. 1B shows a pipe having an electronic socket fusion portion. MW and PAUT inspection is applicable to the electronic socket fusion part.

Similarly, as described above, each non-destructive inspection scanner was required depending on the shape and inspection technique of the inspection object, and accordingly, the operation of installing and disassembling each scanner according to the shape of the inspection object was repeated, increasing efficiency and convenience. There was also a big problem of degradation.

In order to solve this problem, in the prior US Patent Publication No. 2018-0180577, a system capable of simultaneous TOFD inspection and PAUT inspection, including a TOFD tool and a PAUT tool, has been disclosed.

However, No. 2018-0180577 is a non-destructive inspection system applied to a plate, and it is difficult to apply the inspection object to an inspection object having a curved surface such as a pipe, a pressure vessel, or a tube, so there is a limit in that the scalability is poor.

Moreover, when the surface is uneven and not smooth due to cracks or spatters, there is a big problem in that the measurement module does not adhere to the surface of the test object and thus measurement reliability is lowered.

In addition, when performing non-destructive inspection on a cylindrical specimen such as a pipe, the non-destructive inspection scanner is combined with the inspection object by means of a coupling means such as a chain, a belt, or a frame processed to fit the inspection object. In semi-automatic inspection, the user had to manually rotate the non-destructive inspection scanner around the specimen in the circumferential direction. However, in semi-automatic inspection, which is greatly affected by the surrounding environment or human error, signal omission often occurs in the process of data acquisition, and in particular, as the diameter of the specimen increases, the work efficiency also decreases.

On the other hand, the spring washer 477 induces torsion of the screw coupling between the adjustment shaft 475 and the latch 476 to improve the coupling force, and as the movable arm 485 is moved and compressed, the movable arm ( 485) An elastic force may be applied to the moving arm 485 in a direction opposite to the moving direction.

On the other hand, the body coupling part 490 connects the body 470 and the ultrasonic flaw detection jig 50, and at least one coupling shaft 491 of a bar shape extending in the radial direction, and the coupling shaft ( It is formed by being fitted on the 491 , and may include a body pressing means 492 for radially pressing the body 470 toward the test body 50 using elasticity.

With this configuration, the wedge can be coupled to the jig with only one simple operation of turning the latch 476, which has a great effect of increasing work convenience and inspection efficiency. It has the effect of being located on the same line and inspecting with excellent signal sensitivity. Furthermore, unless all latches 476 are released, the fixed arm 480 and the movable arm 485 for fixing the wedge 20 are not separated from the second coupling part 450, so there is little risk of loss, and foreign matter prevention inflow It can also reduce safety accidents caused by missing parts at stations.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention as claimed in the claims.
