The biggest culprit in tank structure failure is fitting split. This is when a hole is cut into your tank to fit a brass fitting weakening the sides of an otherwise sturdy and durable tank. The cutting of the hole alone will not cause a failure, it is the fitting combined with pressure from the contents of the tank.
POLY WELDED FITTINGS
Nu-Tank elminiates fitting split and weak spots by creating a one piece tank and fitting structure by poly fusing and welding the fitting into the tank. The fitting is fused inside the wall of the tank and then welded around the outside, making the tank and fitting become one eliminated fitting ‘weak spot’ or ‘fitting split’. Watch the video showing Nu-Tank’s construction.
40% THICKER WALLS
Nu-Tank’s large water and molasses tanks are poly banded. Banding is a process where the rib moulds on top of the sidewall creating an outward rib. The ‘ribs’ mould an additional 40% thicker. Being thicker makes the tank stronger and last longer.
The pressure inside the tank builds at its base as the tank fills with water or molasses. Due to the force of gravity, the greatest pressure on the tank walls is at the bottom of the tank. Nu-Tank add extra resin when building their large tanks and through its tank manufacturing process the tank moulds to be thicker at the bottom – thicker where the most pressure is.
