A conduit structure for use in an ice transport system consisting of a plurality of individual conduit members, the adjacent ends of which are interconnected by conduit couplings, the conduit structure being of the one-piece uniform cross-section construction and including an intermediate section and first and second opposite end sections which are of a relatively linear configuration, the conduit structure further including first and second relatively arcuate sections interposed one between the first end section and the intermediate section and the other interposed between the intermediate section and the second end section, whereby the conduit structure can be severed within the intermediate section thereof to provide two separate conduit parts, each having a non-linear intermediate section and relatively linear opposed end sections adapted for operative association with the conduit couplings.
