Abstract:
Disclosed herein is a flexible short pipe having a shock absorbing function. The flexible short pipe has flexibility so as to absorb shocks generated in the longitudinal direction of a lifting pipe (or flexible pipe) and have resistance to a bending load or a torsional load when being wound around a roller. The flexible short pipe includes flanges provided at upper and lower ends thereof to be coupled to a unit lifting pipe or flexible pipe. An inner layer has a curved shape and is provided between the upper and lower flanges to allow slurry, lifted up or discharged by a lifting pump, to flow along the inner layer. An outer layer has a curved shape and surrounds the inner layer. A shock absorbing means is positioned between the inner layer and the outer layer, and absorbs longitudinal force and bending force.
