When placing a quantum storage tank to the south of an Extra Utilities 2 Transfer Pipe the tank will be placed but remains in your inventory. (need to sort inventory or access tank GUI for it to appear in inventory). Duplication only appears to occur when placing the tank on the pipe. If the pipe is placed on the tank the duplication does not occur.

This same thing also occurs with Quantum storage units
