The online corrosion early warning device comprises a connecting pipe, wherein one end of the connecting pipe is provided with a film and a compressive porous gasket; the film is positioned on the outer side of the compressive porous gasket; the other end of the connecting pipe is closed and is connected with a detection device; and the material of the film is consistent with a base material of equipment and pipelines to be warned in advance, and the thickness of the film is smaller than that of the base material of equipment and pipelines to be warned in advance. The online corrosion early warning device is simple in structure, a local corrosion state can be accurately reflected, important pipelines and equipment are subjected to management such as purposefully emphasis supervision and early warning and other actual problems, the corrosion early warning is completely and effectively performed, and effective support is provided for corrosion early warning management of high-temperature equipment, long-transport pipelines and other equipment.
Description
Technical field
The utility model relates to a kind of online hardware and pipeline corrosion prior-warning device, is used for the device of testing apparatus, pipeline corrosion degree.
Background technology
In the prior art; For the extent of corrosion of test flow media to high-temperature metal equipment, long-distance transport pipes, often need a kind of test piece be placed in fluid line or the high-temperature service, after after a while, take out test piece; Detect its extent of corrosion, and take adequate measures according to extent of corrosion.
But the use of test piece is troublesome poeration not only, needs manual work from pipeline and equipment, to take out, and detection risk is bigger; And its detection to pipeline, equipment corrosion situation is both untimely also not accurate enough.
Summary of the invention
The technical matters that the utility model will solve is: existing erosion protection system operating process is loaded down with trivial details, and detection risk is big, and testing result is inaccurate, untimely.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: online hardware and pipeline corrosion prior-warning device, comprise connecting pipe, and an end of connecting pipe is established film and resistance to compression porous pad; Film is positioned at the resistance to compression porous pad outside, and the other end seals and is connected with pick-up unit; The material of said film is with consistent by the mother metal of source of early warning and pipeline, and its thickness is less than by the mother metal thickness of source of early warning and pipeline.
The thickness of film is generally by 1/10th of the mother metal thickness of source of early warning and pipeline in the utility model, and it act as by early warning pipeline, corrosion on Equipment degree, and the effect of resistance to compression porous pad then is resistance to compression, makes equipment be applicable to high pressure line and equipment; Because the material of film and pipeline, equipment material are identical, thus through recording sheet by flow-induced corrosion to the time that penetrates, can extrapolate pipeline, corrosion on Equipment situation; After film was etched to and penetrates, fluid was gone in the connecting pipe along the orifice flow of resistance to compression porous pad, can be detected by prior-warning device.Through above design, can reach early warning in time, effectively.Said resistance to compression porous pad promptly is provided with the sheet metal of through hole.
As a kind of improvement project of the utility model, the thickness of aforementioned film is by the 1/5-1/15 of the mother metal thickness of source of early warning and pipeline.
For assurance device can be reused, the thickness of aforementioned resistance to compression porous pad is by the 1-2 of the mother metal thickness of source of early warning and pipeline doubly.When selecting for use the material identical to make the resistance to compression porous pad with mother metal, for guaranteeing that it is reusable and having qualified anti-pressure ability, can do thicklyer during production, be generally 1.5-2 times of mother metal; When selecting for use the material that is superior to mother metal to make resistance to compression porous pad pad, its thickness can be made to such an extent that approach a bit, generally equates to get final product with mother metal thickness.Design makes the not only resistance to compression of resistance to compression porous pad like this, and can reuse.
As the another kind of improvement project of the utility model, said pick-up unit is tensimeter or thermometer.When being gaseous state like the medium of online hardware and pipeline, but the setting pressure table detects; Like the medium of online hardware and pipeline is high-temperature liquid state or when with normal temperature the temperature difference liquid being arranged, but the mounting temperature meter detects.
The utility model has the advantages that: simple in structure, can more accurately reflect the local corrosion state; Realization is carried out the on purpose management of practical problems such as emphasis supervision and early warning to emphasis pipeline and equipment; Perfect, corrode early warning effectively, for corrosion on Equipment forewarning managements such as high-temperature service, long-distance transport pipes provide effective support.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model scheme of installation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Shown in Fig. 1-2, the utility model comprises connecting pipe 1, and an end of connecting pipe 1 is established film 2 and resistance to compression porous pad 3, and film 2 is positioned at resistance to compression porous pad 3 outsides, and the other end seals and is connected with pick-up unit 4; The material of said film 2 is with consistent by the mother metal of source of early warning and pipeline 5, and its thickness is by 1/10th of the mother metal of source of early warning and pipeline 5.
When being gaseous state like the medium of online hardware and pipeline 5, said pick-up unit 4 is a tensimeter, in case after gas gets in the connecting pipe 1, promptly can cause manometric displayed value deviation to occur, thus learning that film 2 is corroded penetrates; Like the medium of online hardware and pipeline 5 are high-temperature liquid states or when with normal temperature the temperature difference liquid being arranged, said pick-up unit 4 is a thermometer, and is same, when the temperature value generation deviation of thermometer, represent promptly that film 2 is corroded to penetrate.
During use, will install and linked together by the pipeline of early warning, equipment through screw thread or flange screw, the medium that makes circulation is contact membrane 2 and by source of early warning or pipeline simultaneously, notes the time point that device begins contact medium, i.e. zero-time; Then, under the corrosion of film 2 at medium, penetrate, medium is gone in the connecting pipe along the orifice flow of resistance to compression porous pad 3, causes temperature or pressure in the connecting pipe 1 to change, and the testing staff can in time be write down the time point that penetrates, i.e. concluding time; At last,, calculate, be i.e. millimeter/year, reached the purpose of the corrosion forewarning management of hardware by the speed of source of early warning corrosion according to zero-time, concluding time and film thickness.
In the use; Two to five prior-warning devices are installed in respectively by zones different on early warning pipeline, the equipment; Can reduce other factors and disturb, reach and more accurately reflect the local corrosion state, perfect, carry out by the effect of source of early warning corrosion prediction effectively.
