Abstract
The utility model discloses a kind of reference block burying longitudinal defect for small diameter tube rayleigh waves inspection near surface, including pipe sample, offering through hole in the wall of pipe sample vertically, three graduation marks are carved with on the surface of pipe sample 1, and the center of circle of through hole is 1mm with the spacing of pipe sample outer wall.This utility model can be used in small diameter tube rayleigh waves inspection near surface and buries the detection of longitudinal defect.
Description
Technical field
This utility model relates to a kind of reference block, is specifically related to one and buries for small diameter tube rayleigh waves inspection near surface
The reference block of longitudinal defect.
Background technology
In recent years, the development of the industry technology such as processing and manufacturing, material, metallurgy, assembling is very fast, and the development of technology is to material
Material and the surface of component and near surface quality propose the highest requirement, meanwhile, large quantities of in order to make these technology be applied to
Amount commercial production, does not has perfect detection means to will be unable to ensure material and the quality of component.Affecting material and component quality
And in the factors of safety, the defect being hidden in material and component near surface is often the origin of some critical defects, more
There are disguise and hazardness.There is longitudinal defect in the F91 short tube such as certain station boiler high temperature superheater, crackle easily germinating at this,
Extension, until steel pipe leakage causes unplanned outage accident.In running, station boiler high temperature reheater pipe also occurred
Germinating at longitudinal defect and crackle, and extend, cause the repeatedly leakage of steel pipe, ultrasonic surface wave technology has it can be found that table
Face and the feature of near surface inner defect, but prior art does not has to bury for small diameter tube rayleigh waves inspection near surface
Hide the reference block of longitudinal defect detection.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, it is provided that a kind of for small diameter tube surface wave
Detection near surface buries the reference block of longitudinal defect, and this reference block can be used in small diameter tube rayleigh waves inspection near surface and buries
The detection of longitudinal defect.
For reaching above-mentioned purpose, described in the utility model bury longitudinal defect for small diameter tube rayleigh waves inspection near surface
Reference block include pipe sample, offer through hole in the wall of pipe sample vertically, three graduation marks, through hole are carved with in the surface of pipe sample
The spacing of the center of circle and pipe sample outer wall be 1mm.
A diameter of 1mm of described through hole.
The a length of 100mm of pipe sample.
Described three graduation marks are each parallel to the axis of pipe sample.
Article three, graduation mark is 1/4 pipe sample girth, 1/2 pipe sample girth and 3/4 pipe sample girth with the hoop distance of through hole.
This utility model has the advantages that
Described in the utility model bury the reference block of longitudinal defect for small diameter tube rayleigh waves inspection near surface and include
Pipe sample, the inwall of pipe sample is provided with through hole vertically, and graduation mark is carved with on the surface of pipe sample, in use, passes through ultrasound examination
Instrument and surface wave probe complete through hole in pipe sample and the detection of graduation mark, thus realize small diameter tube rayleigh waves inspection near surface
Bury the detection of longitudinal defect, by the contrast of this reference block with detection small diameter tube, complete small diameter tube defect size and position
Determination, simple in construction, there is stronger practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 be pipe sample, 2 for through hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail:
With reference to Fig. 1, the contrast burying longitudinal defect for small diameter tube rayleigh waves inspection near surface described in the utility model
Test block includes pipe sample 1, offers through hole 2 in the wall of pipe sample 1 vertically, and three graduation marks, through hole 2 are carved with in the surface of pipe sample 1
The spacing of the center of circle and pipe sample 1 outer wall be 1mm.
It should be noted that a diameter of 1mm of described through hole 2；The a length of 100mm of pipe sample 1；Article three, graduation mark is the most parallel
Axis in pipe sample 1；Article three, graduation mark is 1/4 pipe sample 1 girth, 1/2 pipe sample 1 girth and 3/4 pipe sample with the hoop distance of through hole 2
1 girth.
Special test block for small diameter tube rayleigh waves inspection near surface inner defect described in the utility model can be used in
Ultrasound measuring instrument and the verification of surface wave probe composite behaviour, the detection sensitivity of surface wave and the determination of defect size, detection
The adjustment of distance and the determination of defective locations, the test of the surface wave sound field degree of depth.
