Abstract
There is provided a coated expandable-contractible flexible pipe capable of properly securing the anti-corrosive performance without damaging a coating even in the case where the coated expandable-contractible flexible pipe coated with the coating oscillates or expands/contracts. The coated expandable-contractible flexible pipe includes: an expandable-contractible flexible pipe having a pair of joints to be connected to a fluid pipe and a connecting pipe for connecting the joints to each other, the pair of joints being mutually oscillatable and expandable/contractible; and a resin or rubber coating that coats the expandable-contractible flexible pipe. The coating includes a joint coating portion in close contact with the joint, a pipe coating portion in close contact with the connecting pipe, and a looseness portion formed between the joint coating portion and the pipe coating portion so as to allow the oscillation or expansion of the expandable-contractible flexible pipe.
