Description
Technical field
The invention belongs to weld seam detection fields, and in particular to a kind of Φ 377 is with lower pipe fitting butt girth welding seam X-ray detection work
Dress and detection method and application.
Background technique
The detection of the docking circumferential weld of Φ 377 (diameter 377mm) or more can enter x-ray flaw detector inside pipeline,
Carrying out flaw detection is carried out to it.The docking circumferential weld below of Φ 377, since x-ray flaw detector cannot be introduced into the exposure of pipeline inside center
Flaw detection, can only take double-walled list shadow mode single exposure one to open film.Double-walled list shadow be segmented transillumination, transillumination direction in principle with
Transillumination vertical with workpiece surface is preferred, and to avoid penetrating source weld seam image and film side weld image overlap, can also be used and be inclined
Oblique illumination, but weld seam oblique projection can be such that defect image is distorted.In actual operation, due to the limitation of field condition, have
When oblique illumination angle be not easy to be aligned, so, when caliber is larger, preferably ray window of tube is adjacent to and penetrates source face of weld,
Irradiate ray with vertical direction.Ray machine is moved at docking circumferential weld by the flaw detection of double-walled list shadow method first, exposure shooting one
After secondary, pipeline is rotated, every rotation single exposure shooting is primary, completes within rotated pipe one week 100% flaw detection.The method effect
Rate is low, and personnel labor intensity is big, and Ray machine is long using the time, increases the harm of environmental radiation.
Summary of the invention
The purpose of the present invention is to solve the technical problems existing in the prior art, a kind of Φ 377 is provided with lower pipe fitting
Butt girth welding seam X-ray detection tooling and detection method and application, the tooling and detection method realize Ray machine and fix, and turn
It starts building part, multiple egative films of single exposure save manpower and material resources；Extend the service life of defectoscope；Reach while shooting more
Circumferential weld, reduces the exposure frequency of machine, while decreasing the radiation to human body.And tooling is simple and efficient to handle, and it is real
It is strong with property.
In order to solve the above technical problems, the technical solution of the present invention is as follows:
A kind of Φ 377 is with lower pipe fitting butt girth welding seam X-ray detection tooling, including several rows support dress disposed in parallel

Corresponding every 3 conduit saddles or 4 conduit saddles or 5 conduit saddles are one group, install a ray at the lower central position of every group of conduit saddle
Baffle is arranged between adjacent two Ray machines in machine.
Because the height of defectoscope and pipe fitting is 700mm, 3 pipe fittings are within the scope of a transillumination, so exposing 3 simultaneously
Pipe fitting；If increasing height, can be detected simultaneously by becoming 800mm from 700mm by 4, most 5 pipe fittings, if increasing distance again,
Time for exposure increases, and efficiency reduces.
Preferably, the height of the support device is 600mm-800mm；Distance be it is best, high-efficient, negative quality is good.
The distance between adjacent conduit saddle is 390-410mm.400mm or so is, Φ fixed according to the circular arc of 377 pipe fitting of Φ
377 pipe fittings below can use；For the pipe fitting for being less than Φ 377, conduit saddle, control can be adjusted according to detection pipe pipe diameter size
The crack of two adjacent detection pipes is made between 20-25mm, convenient for differentiating pipe fitting on detection egative film.
It is further preferred that the multiple that the number for the conduit saddle that the top of each support device is installed is 3.
It is further preferred that the height of the conduit saddle of underface installation Ray machine is 5- than the difference in height of adjacent conduit saddle
10cm。
3 conduit saddles form an approximate semicircle, and the purpose for making intermediate conduit saddle be slightly above two neighboring conduit saddle is to guarantee quilt
The distance of radiographic source of the film to Ray machine on three pipe fittings of same Ray machine detection is identical.
Preferably, the support device includes crossbeam and the supporting leg that is supported to the both ends of crossbeam.
Preferably, the conduit saddle is arc-shaped, and the diameter of circular arc is 390-410mm.
400mm be it is fixed according to the circular arc of 377 pipe fitting of Φ, 377 or less Φ can be used, just with 400mm can.
Application of above-mentioned 377 or less the X-ray detection tooling of Φ in the detection of pipe fitting butt girth welding seam, it is especially small in diameter
Application in the pipe fitting butt girth welding seam detection of 377mm.
The method detected using above-mentioned detecting tool to girth joint, is included the following steps:
1) pipe fitting is placed on the conduit saddle of detecting tool, so that the ray beam center of the girth joint of pipe fitting and Ray machine
Aligned in position；
2) film is fixed at the girth joint of pipe fitting, and is aligned film center with the ray center of Ray machine；
3) Ray machine is opened, pipe fitting is rotated to a circle simultaneously, completes 100% detection of girth joint.
Preferably, the pipe fitting detected by same Ray machine is same specification.
Same specification, same wall thickness, the time for exposure is identical, guarantees that negative quality is met the requirements of the standard.
Application of the method in the detection of pipe fitting butt girth welding seam is especially docked in pipe fitting of the diameter less than 377mm
Application in circumference weld inspection.
Advantageous effects of the invention are as follows:
1, method of the invention has been successfully applied to the flaw detection of diameter of phi 377 or less pipeline batch film making circumferential weld, the party
Ray machine is fixed in method, high-volume work is no longer needed to move repeatedly Ray machine, only rotates pipe fitting to be measured, is saved
A large amount of manpower, greatly reduces labor intensity；
2, detecting tool of the invention can be exposed film making multiple-pass weld within the same time, improve detection effect
Rate；Ray machine, which works, to be shortened total time, opposite to extend machine service life, substantially between X-ray radiation quantity X crack detection room exposure
Degree is reduced.
