STORAGE TANK EXAMINATION AND REPAIR


Storage tank examinations should be executed during the manufacturing process or during the revision of the operating tanks. The examinations detailed in the following should be preceded by a visual examination in each case, thus filtering rude surface errors prior to the more costly examinations. Surfaces to be examined should be well prepared since the quality of preparation will substantially influence the punctuality of examinations.
The examination of the brevity of the storage tank is of key importance during occasional revisions including mapping wall attenuation due to corrosion as well as crack detection of the mostly demanded welded seams (weld sections).

We employ the following methods during storage tank examination:


Ultrasonic test:  mapping wall attenuation due to corrosion should be executed systematically with ultrasonic wall thickness measurement of regular frequency.


Vacuum test: in the case of double-seated tanks the bottom plate cannot be examined directly. Information on its status can be collected via the vacuum test of the space between the two bottom plates.


Vacuum-box test: it is used for the examination of the length and round welt (corner welts) as well as the intersections of the tank. 

Penetration and magnetic particle testing: execution of crack detection, possibly on both sides, along the welding each with a five cm detection width.


Eddy current examination: it provides a complete and thorough view of the level of attenuation on the bottom plate.

 

Depending on the nature of the error, we also undertake technical rectification of the tank as well. (without weld)


Our professional staff has a long history of tank examination and our enterprise has permanent contracts with our Hungarian customers (including MOL PLC, TEVA Pharmaceutical Industries Ltd., TVK PLC, ÖMV).
