Ocena możliwości zastosowania powłoki laminatowej do naprawy i wzmocnienia płaszcza stalowego zbiornika paliwowego o osi pionowej

The article presents the course and results of research which purpose was aimed at evaluation of selected properties of polyester-glass coatings used to repair and strengthen the jackets of steel cylindrical tanks with a vertical axis for the storage of liquid fuels. Through experimental research, the issues related to the risk of delamination of the steel-laminate composite as a result of dynamic loads, as well as the impact of different temperatures at which the laminate operates inside the tank on the hardness of the laminate coating were identified. The stability of the dimensions and shape of the laminate coating in exceptional conditions where it is subjected to an exposure to elevated temperature was also assessed. An attempt was also made to answer the question about the impact of the use of a laminate coating on the load bearing capacity of the tank shell strengthened with it.
