Description
Technical field
It the utility model is related to Ultrasonic Nondestructive technical field, more particularly to a kind of small diameter tube outside weld sliding block angle welding
Ultrasonic detection device.
Background technology
Ultrasonic phase array detection technique is produced and received ultrasonic beam using more element transducers of different shapes, passes through control
Each array element launches the different delays time of (or reception) pulse in transducer array processed, changes sound wave and reaches when certain is put in object
Phase relation, the change of focus and sound beam direction is realized, so as to realize the beam scanning of ultrasonic wave, deflection and focusing.Then adopt
The method being combined with mechanical scanning and electron scanning realize image be imaged.
Small diameter tube is outer diameter D=32~89mm, wall thickness t=4~14mm heating surface tubes in boilers, and thermal power plant is most of
Superheater, economizer, reheater, water-cooling wall all within the above range.In order that boiler heating surface is relatively fixed, generally in pot
The sliding block fixing device to stagger up and down is provided between stove panel-pipe of heating surface.However, due to the sliding block being welded on the pipe of pipe row
What is be subject to is the tension and shear stress of an alternation, and the thermal expansion of two kinds of materials of pipe and sliding block of pipe row is different, from
And cause the cracking of sliding block.When the pipe expanded by heating sliding block of pipe row, which is in, to be staggered up and down, one end of sliding block is drawn by alternation
Stress and shear stress, the sliding block of the pipe of two pipe rows mutually prize the cracking for exacerbating sliding block.This can cause pipe sliding between arranging
Block comes off, and the pipe that pipe is arranged is torn wound, and causes pipe to position the row's deformation of abnormal and pipe between arranging, and easily causes pipe explosion accident hair
It is raw.
At present, path pipeline is densely distributed, in installation process in the three dimensions of solid, cross-operation point multiaspect
Extensively, ray or the conventional ultrasound Non-Destructive Testing of progress 100% are usually required that to pipe weld, to ensure installation quality.But
Limitation is respectively provided with using ray detection or conventional ultrasound detection, first, using ray detection, because ray has radiation, meeting
Human body is damaged, particularly in terms of extra-supercritical unit, the wall of small diameter tube is more and more thicker, and small diameter tube both sides almost turn into
The blind area of ray detection, although certain effect is had using the gamma source detection of heavy dose, with radioactive source to surrounding environment
Pollution and injury to testing staff compare, lose more than gain, also, when carrying out ray detection, need to be by installing space
The installation personnel of interior more settings is cleared out a gathering place, and takes the set-up time, influences to install the progress of construction project；Second, using conventional super
Sonic detection, although it is more sensitive to area defect, the ability of its detection volumetric defect is poor, and defect is shown
Not directly perceived, detection method is single, and sensitivity is low, and testing result is larger by man's activity.From the foregoing, due to ray detection and
Conventional ultrasound detection technology existing deficiency in itself, in work progress, often brings many inconvenience.
