Abstract: Agricultural chemicals, such as herbicides, pesticides and fertilizers, are typically sold as a liquid concentrate and are transported in plastic tanks which commonly range from 15-160 gallons in size. Often these tanks are manufactured using conventional rotational molding techniques from a thermoplastic such as high density polyethylene (HDPE). When full of liquid these tanks are heavy and are typically moved using a forklift or other suitable powered apparatus. The bottoms of these tanks flex up and down when full and further vary in size due to manufacturing variances and the physical properties of the plastic itself. The flexible suction pipe is typically installed in one of these tanks and is designed to keep the inlet of the suction pipe at or near the bottom of the tank despite flexing and other variables to maximize withdrawal of fluid from the tank. The flexible suction pipe includes an elongate flexible bellows which expands and contracts as the situation may demand.
