Flexible siphon pipe for tank car

摘要

An eduction or siphon pipe in a railway tank car extends from adjacent a bottom sump area to a fitting in a top area of the car. The railway tank car has a generally curvilinear inner wall, and the eduction pipe is provided with a shape corresponding to the generally curvilinear inner wall and is supported in proximity thereto. This enables the eduction pipe to readily accommodate radial distortions of the railway tank car during transport. In addition, all (or substantially all) of the fluid commodity in the railway tank car can be withdrawn through the eduction pipe since the lower end thereof may be positioned in close proximity to the bottom sump without concern for radial distortion or deflection of the tank car.
