Description
Technical field
The invention belongs to oil equipment technical field, and in particular to a kind of preservative tank antiseep method of testing.
Background technology
In oil-processing enterprises, large anticorrosion tank is widely used in the links of production, the big portion of present preservative tank
Point be steel part, internal roller coating or spraying corrosion resistant coating, half of which are to use anti-rot plastic, due to need for a long time with the corruption such as soda acid
Corrosion liquid is contacted, and can not all there be leakage point at various positions in preservative tank, therefore anti-corrosion material and processing technology are required
It is very high, strict test is needed after preservative tank process finishing, present method of testing is simple, and the characteristic to anti-rot plastic is not comprehensive
Understanding, therefore the assay of accurate specialty can not be provided, the market prospects to product can not make accurate judgement, influence
The development of enterprise.
The content of the invention
To solve the above problems, the invention discloses preservative tank antiseep method of testing, can accurately judge that anticorrosive coat is
It is no to have leakage point, anticorrosive coat ultimate elongation is adjusted, the impact and corrosion for it is more adapted to acid-base solution, extension uses the longevity
Life.
To reach above-mentioned purpose, technical scheme is as follows：
Preservative tank antiseep method of testing, it is characterised in that：Comprise the following steps：
（1）Preservative tank is arranged in 15-20 DEG C of environment, other branch mouthful are all sealed with cover plate in addition to manhole；
（2）Circular hole is beaten on preservative tank surface, Steel outer wall is only punched, internal anticorrosive coat is not damaged；
（3）The welding point at circular hole, prepares evacuator, and the exhaust tube of evacuator is connected to joint；
（4）From manhole toward water filling in preservative tank, midway adds 1-2% ethanol, stirring, fills after water and to seal manhole；
（5）Preservative tank surface is heated to 120-125 DEG C and kept, starts evacuator 40-50min, pressure is -6 ~ 8MPa；
（6）Evacuator is closed, natural cooling 3-4h opens manhole, examined with ohmmeter, a test pencil is put into water, another
Branch test pencil contact preservative tank outer surface, resistance value illustrates that quality reaches a standard higher than 0.4m Ω；
（7）Discharge water, the exhaust tube of evacuator is withdrawn；
（8）After internal cleaning is clean, electricity consumption Spark plug optical fiber sensor, it is qualified after faced joint is removed, circular hole is sealed, and spray painting is packaged into
Storehouse.
As a modification of the present invention, the circular hole arrangement density is 2/m2。
As a modification of the present invention, the manhole is arranged on the top of preservative tank.
As a modification of the present invention, the joint is hydraulic quick coupling.
The beneficial effects of the invention are as follows：
Preservative tank antiseep method of testing of the present invention, anticorrosive coat has altogether when examining and is subjected to 3 and resits an exam to test, and one is that temperature is examined
Test, two be deformation test, and three be that, either with or without leakage point, the material of anticorrosive coat in itself is completely can be anticorrosive in 10 years, is closed
Key is that anticorrosive coat operationally can be by fortuitous events such as temperature change, impulsive forces, and the length of time one can cause leakage, present invention inspection
Using the combined detection method of solution infiltration+negative pressure ventilation during survey, in step（2）（3）In, outside heating, the inside adds water, anti-corrosion
Influence of the limiting temperature of the corrosive liquid such as soda acid to anticorrosive coat when layer is in the limiting condition colded and heat succeed each other, completely simulation work,
This test is passed through, the temperature of corrosive liquid will not leak anticorrosive coat；120-125 DEG C is heated on the outside of preservative tank, is made interior
The anticorrosive coat softening transform in portion, at the same start evacuator vacuumize, by anticorrosive coat fitted with anti-corrosion top tank structure it is even closer,
In the 5-8 without departing from；While softening transform in the case of cold in anticorrosive coat is warm outside, if such deformation will not make to prevent
Rotten layer cracking leakage, then when working future corrosive liquid wash away and deformation in ageing process is all without making anticorrosive coat
Leakage；Present invention detection leakage point is the ethanol for adding 1-2% in water by adding water, and is examined using the good characteristic of ethanol infiltration
Test, if leak source, ethanol can be dug into the anticorrosive coat back side, touched Steel outer wall, examined with ohmmeter, resistance value meeting
Very little is zero, can whereby identify that anticorrosive coat has leak source, if resistance value illustrates that quality reaches a standard higher than 0.4m Ω, anticorrosive coat
Zero defect, if resistance value is 0.1m Ω or so（Resistance value is not small, but is below 0.4m Ω）, illustrate anticorrosive coat without leak source, but
That some areas anti-corrosion layer surface or the back side have crackle or defect, can use but the life-span it is not long, present inventive concept is skilful
Wonderful, simple to operate, a people can just complete, and method is special, can accurately judge whether anticorrosive coat has leakage point, while to anti-
Rotten layer ultimate elongation adjustment, the impact and corrosion for it is more adapted to acid-base solution, service life extension 60%.
