What is a Loading Arm?
Loading arms are self-supporting structures, generally composed of three rigid pipes, called respectively; internal arm, external arm and drip tube, connected by rotating joints that allow flexibility of movement in
the different axes.
Due to the weight of the pipes a balancing is necessary, which is done by means of a counterweight or a gas or spring cylinder.
Loading arms are used for the transfer of fluids or gases from storage tanks to mobile tanks, by road, rail or sea.
