Storage tank safety is increasingly subject to people's attention, and wherein bottom of storage tank corrosion is to cause the unsafe key factor of storage tank.At present
Bottom of storage tank liquid typically contains organic acid, inorganic salt, the impurity such as sulfide and microorganism, adds outside tank skin by environmental factors
Impact makes oil tank be corroded, and substantially reduces the service life of storage tank.Different types of oil tank, due to residing work condition environment
With the difference of storage tank material, corrosion condition has larger difference, accounts for whole world steel due to corrosion of steel, the quantity scrapped every year
The 20% of material volume of production, the research therefore carrying out Corrosion of Tanks is very urgent.
Existing lacing film system is only capable of the corrosion condition studying lacing film in a static condition, to such an extent as to actual oil tank
Interior corrosion condition has bigger difference, inaccurate to the predicting residual useful life of storage tank, causes tank leak, to such an extent as to causes
Casualties and property loss.Therefore, oil product is carried out significant to the research of Corrosion of Tanks speed.This negative pressure draining system
System adapts to a kind of system that can be utilized for various negative pressure draining that this requirement grows up just.

Publication date is the patent of invention of 20100224, discloses a kind of system being measured corrosion rate inside oil tank by hanging slice method,
It is characterized by: in housing, be cased with lining, in lining, be cased with annular lacing film, by the isolation of snap ring location, pad between two lacing films
Lacing film and lining are fixed on alternately on inwall positioning table by ring.This device is used for detecting tube inner wall corrosion condition.
In order to study the corrosion of steel speed under actual dynamic operation condition, general corrosion testing all uses hanging slice method, will
Sheet metal to be measured is put in the reactor in the corrosion rate test device of static state and is slowly corroded, and after slowly corrosion
Mass change according to lacing film determines corrosion rate, it is seen then that current reactor is static environment, causes corrosion testing to be only capable of quiet
Testing in state environment, it is difficult to simulation dynamic environment, the data of test are not accurate enough, and by arranging the survey of lacing film in a kettle.
Amount mode speed is relatively slow, can only obtain the average corrosion rate of a period of time.
