Description
Technical field
The present invention relates to the non-destructive detecting device field of pipeline, particularly a kind of to be used for cross pipeline low-angle angle welding
Magnetic memory detection device.
Background technology
Angle welding is widely used in the fields such as petrochemical industry, electricity power, railroad bridge, especially petrochemical industry
All there is angle welding in long oil and gas pipeline, chemical pipeline, pressure vessel, flange, valve, townhouse pipe etc..Due to angle welding pressure-bearing
Afterwards stress state is more complicated, and most single-sided welding easily produces incomplete penetration defect when adding manufacture, therefore carries out timely and effective
NDT and NDE work be extremely necessary.
But conventional lossless detection method is difficult to find the defect that angle welding is present, such as ultrasound examination, for fillet welding
Seam, the structure that caliber is little, tube wall is thin, back wave is difficult to get to weld seam position；Magnetic Flux Leakage Inspecting is limited by fillet welding gap space and angle
Restriction, magnetizing assembly cannot carry out uniform magnetization to angle welding；Radiographic inspection is for no matter fillet welding seam defect is in Pipe installing
Cannot all be judged after stage or in-service operation, be only applicable to the quality testing that Pipeline butt is sewn on erection stage, be managed
Not only fine crack recall rate is very low after road operation, also needs the medium whole emptying in system during film making, and inspection cost is high, work
Make efficiency very low；The methods such as common magnetic, coloring cannot find latent crack and internal porosity.
Metal magnetic memory detection technology can quick and convenient, effectively detect the stress concentration of weld seam, especially angle welding
Position and defect, defect that can be effectively to existing is diagnosed.Although magnetic memory detection technology is in China's only more than ten years
Development course, but the technology ferromagnetic component early diagnosis with life-span anticipation in terms of application prospect, industry has been obtained special
The generally accreditation of family scholar.Metal magnetic memory can solve the problem that conventional Non-Destructive Testing insurmountable metal be on the verge of damage before morning
Phase diagnoses problem, and for ferromagnetic component failure and life appraisal strong technical support is provided, therefore aobvious in field of non destructive testing
Show its unique advantage.But at the scene in measurement process, current Magnetic memory testing encounters oblique pipe communicated wire fillet welding
The problem that low-angle side cannot pass through due to narrow space detection means is sewn on, while there is oblique pipe communicated wire angle welding
The detection path of this space curve lacks the problem of accurate detection device.
Metal magnetic memory technique is to be recorded to propose the end of the nineties 20 by Russian scholar Du Bofu, metal magnetic memory technique
It is the piezomagnetism mechanism based on ferromagnetic material under earth's magnetic field and service load effect, stress and deformation concentration zones can occur magnetic
Farmland tissue orientation and it is irreversible tend to again, the stress distribution of zero component can be reflected by Distribution of Magnetic Field, in work
Make still to retain after load disappears.It is distributed by detection means Surface field, can not only finds component gross imperfection, more can be had
The danger zone that effect detection ferromagnetic material stress is concentrated, is one of Dynamic Non-Destruction Measurement 21 century with extensive prospect.Simultaneously
Magnetic memory testing has prevented the electromagnetic pollution equipped without the need for artificially being magnetized to testee.
While metal magnetic memory technique certainly, because its generation and the time developed are shorter, need at many aspects
It is further perfect.Due to the undue qualification and accuracy for relying on manual operation in measurement, measurement result precision is caused not
High, measurement efficiency is low, and the repeatability for measuring is poor.

Because conventional lossless detection method cannot detect angle welding, and discontinuous place of the angle welding often in structure is easy
Stress concentration is produced, therefore easily there is the accidents such as leakage, blast after coming into operation in angle welding.Metal magnetic memory detection technology
Stress concentration position and the defect of angle welding can quick and convenient, be effectively detected, but has currently encountered oblique pipeline and mutually be passed through
The problem that line angle weld seam cannot be passed through in low-angle side due to narrow space detection means, while there is oblique pipe communicated wire
The detection path of this space curve of angle welding lacks the problem of accurate detection device, and the little angle of oblique pipeline was not measured in recent years
The suitable detecting instrument of degree weld seam, the design invention of the device is to avoiding low-angle angle welding weld leakage from causing considerable safety thing
Therefore it is significant.
