Abstract
A double wall storage tank system has its walls bonded together in a defined intermittent manner. The storage tank system comprises a tank having a cylindrical-shaped main body and end walls at each end thereof. A continuous wall covers the tank and is bonded thereto in a defined, e.g. helical pattern. Unbonded wall portions between the bonded wall portions form flow channels extending the full length of the cylindrical-shaped main body of the tank such that leakage through any part of the tank or continuous wall is detectable.
Claims25
A double wall storage tank system having cylindrical-shaped walls structurally bonded together in a defined intermittent manner whereby flow channels are created to receive leaked liquid, said system comprising:
- (a) a tank having a cylindrical-shaped main body and having an end wall attached at each end thereof, said tank having a capacity of at least about 500 gallons liquid;
- and
- (b) a cylindrical-shaped continuous wall which covers the cylindrical-shaped main body of the tank so as to extend less than about one-half inch in height from the tank and which is intermittently bonded thereto in a defined pattern, whereby said pattern extends at least partially about said cylindrical-shaped main body to create unbonded wall portions between the bonded wall portions thereby forming flow channels extending substantially the full length of the cylindrical-shaped main body such that leaked liquid through the tank or the continuous wall is capable of being detected.
A double wall storage tank system having cylindrical-shaped walls structurally bonded together in a defined intermittent manner whereby flow channels are created to receive leaked liquid, said system comprising:
- (a) a tank having a cylindrical-shaped main body and having an end wall attached at each end thereof;
- and
- (b) a cylindrical-shaped continuous wall of a fibrous reinforced resinous material which covers the cylindrical-shaped main body of the tank and which is intermittently bonded thereto in a defined pattern, whereby said pattern extends at least partially about said cylindrical-shaped main body to create unbonded wall portions between the bonded wall portions thereby forming flow channels of a continuous nature extending substantially the full length of the cylindrical-shaped main body such that leaked liquid through the tank or the continuous wall is capable of being detected;
- and
- (c) an end cap over each end wall of the tank to create a closed space therebetween, each said end cap being structurally secured to the continuous wall so as to form an enclosed structure which substantially follows the contour of the main body of the tank, whereby the flow channels formed between the tank and the continuous wall are in communication with each said closed space wherein each of the bonded wall portions of the continuous wall is from about one-half inch to about one inch in width and said bonded wall portions are spaced from about one inch to about three inches apart.
A double wall storage tank system having cylindrical-shaped walls structurally bonded together in an intermittent manner whereby a helical flow channel is created to receive leaked liquid, said system comprising:
- (a) a tank having a cylindrical-shaped main body and having an end wall attached at each end thereof, said tank having a capacity of at least about 500 gallons liquid;
- and
- (b) a cylindrical-shaped continuous wall which covers the cylindrical-shaped main body of the tank and which is intermittently bonded thereto in a helical pattern, whereby said helical pattern extends about said cylindrical-shaped main body to create unbonded wall portions between the bonded wall portions thereby forming the helical flow channel extending substantially the full length of the cylindrical-shaped main body such that leaked liquid through the tank or the continuous wall is capable of being detected.
