A sectional panel tank comprises one or more side wads that are joined together in forming the sectional panel tank. One of the side wall comprises a first unit panel having a first extension at a first edge of the first unit panel and a second unit panel having a second extension at a second edge of the second unit panel. By combing the second extension to the second extension, the second unit panel is joined to the first unit panel for providing a continuous surface of the side wall. No gasket is needed between the first extension and the second extension. A method of making the sectional panel tank is also disclosed. A method of making prefabricated unit panels with lining sheets is further disclosed for the sectional panel tank.

A method of creating a stand-off between insulation and chime on a storage tank is provided. A plurality of tank chime spacers are positioned in space relation to each other such that the bottom of the tank chime spacer is positioned on the tank chime and one of the peripheral side walls of the tank chime spacer is positioned adjacent to the sidewalls of the storage tank to create a gap between the tank chime and the sidewalls of the storage tank. Each of the tank chime spacers has a body with a top, a bottom and peripheral side walls.

A system of connecting a stiffener to the sidewall of a grain bin using a stud bolt having a first threaded end, a second threaded end and a feature positioned between the first end and a second end. A sealing member is positioned over the first end of the stud bolt, which in one case is a metallic washer with an affixed compressible sealing member. The first end of the stud bolt is inserted into a hole in the sidewall and an inner nut is placed over the first end inside the sidewall. As the inner nut is tightened, the feature is pulled toward the exterior surface of the grain bin thereby causing the sealing member to form a seal with the exterior surface of the grain bin. The second end of the stud bolt is inserted into a hole in the stiffener which is tightened onto the stud bolt.

A system for detecting human entry into a container using electromagnetic imaging to generate image maps of the container. The system includes a door monitor configured to detect an entry door open event associated with the container. The system uses one or more processors and a memory with instructions to generate a baseline image map of the container, detect an entry door open event with the door monitor associated with the container, generate a post entry door open event image map of the container, and compare the baseline image map generated before the entry door open event with image map generated after the entry door open event.

This application describes tank wrap systems that cover containers. The tank wrap systems include tank wraps having a single sheet of a first polymer having an interior surface formed of the first polymer that faces a container, and an exterior surface formed of the first polymer that faces opposite the interior surface. A first coupling member formed of a second polymer is affixed to the exterior surface of the single sheet, and the first coupling member is couplable to a second coupling member of another tank wrap to couple the tank wrap and the other tank wrap and allow the tank wrap system to removably cover the exterior of the container.
