FLUID TRANSPORT TUBE

摘要

PROBLEM TO BE SOLVED: To provide a fluid transport tube durable to repeated bending and stretching and hardly having an external mechanical or thermal influence. SOLUTION: A protective coil 3 formed by spirally winding a metallic wire rod 2 is put on the circumference of a resin and/or rubber-made tube 1 for carrying a fluid therein. The inside diameter of the protective coil 3 is set larger than the outside diameter of the tube 1 to form a gap between them.
