Tank Connection Battern Bar Design: Fig 1 & 2

Tank Connection’s beam design uses flange stiffeners for maximum beam strength. The battern bar attachment slot does not attempt to pre-form threads for screw that attach the batten bar to the beam, since a 1/4″ bolt thread pattern requires tolerances in excess of what can be extruded in aluminium. Instead this slot is sized for a thread rolling fastener that can be removed and installed multiple times in the same slot. The battern bar is designed such that when the battern is tightened, the panel is pushed into the gasket. This is the only battern system with three redundant features to ensure a leak free design. The battern legs are also designed to prevent twisting when personnel access the dome roof.

Competitor Detail: Fig 3

The attempt to form threads in the beam at the extrusion mill is not practical due to normal extrusion process tolerance. A screw will strip out the threads in the slot after one or two installations and will not develop maximum strength. No flange stiffeners are allowed due to manufacturing limitations. The gasket compression is the sole device for sealing the joint.

Tank Connection can also design and install stand alone domes for any type of steel tanks (bolted or welded) as well as concrete tanks. In many instances, an aluminium dome may be requested to replace an existing roof that is failing or the customer may wish to add a dome to an open top tank. Tank Connection can provide the right solutions, the most economical design and the highest quality aluminium dome for your application.
