Abstract: A clamping system secures a discharge spout of a bulk storage bag to an outer surface of a process interface connection. The clamping system includes a first clamping arm and a second clamping arm. Each clamping arm has a fixed end and a free end arranged such that the free end can pivot about the fixed end between a clamping position and an open position. Each clamping arm has an inner clamping surface configured to clamp a portion of the discharge spout against a portion of the outer surface of the process interface connection when the clamping arm is in the clamping position. The inner clamping surfaces are arranged such that when the first and second clamping arms are in the clamping position, the inner clamping surfaces cooperate to clamp the discharge spout against substantially the entire outer surface of the process interface connection.
