Background technology
Substantial oil, product oil and hazardous chemical metal tank are used in oil, petrochemical industry and storage sector, is used as the storage of oil product or industrial chemicals, production.These media have the characteristics such as inflammable, explosive and corrosion mostly, big with single tank body storage volume, the features such as tank body quantity is more, once accident occur will cause great economic loss, influence the security of the lives and property of the people.
Storage tank bottom plate is the region of corrosion most serious in storage tank, and the key area of storage tank preservation ＆ testing is storage tank bottom plate.Need to generally stop using and could carry out tank bottom detection with some non-destructive detecting devices after clear tank.For some big tanks, all operationss process may be more than 30 days, so correlative charges is at a relatively high.On the other hand, by existing maintenance strategy, it is probably the good tank that need not be repaired to pay a large amount of expenses and carry out the tank of clear tank inspection, such case often occurs in real work, and with the improvement of material, construction, maintaining method in recent years, the service life of tank body constantly extends, although therefore periodic maintenance ensure that the safe operation of tank body to a certain extent, its economy has badly influenced operation cost.It is often the case that some tanks just had occurred that heavy corrosion before scheduled maintenance, and other tanks are far from unwanted corrosion occur when the scheduled maintenance phase is reached, also.
