<p>PROBLEM TO BE SOLVED: To provide a flexible hose for performing piping execution operation easily without losing the flexibility in the hose by eliminating the generation source of noises being generated when a helium gas is circulated inside a bellows-like flexible hose for connecting a compressor unit to a refrigerating machine unit. SOLUTION: A flexible pipe is fitted to the inner surface of the bellows-like flexible hose made of stainless steel for connecting the compressor unit to the refrigerating unit, thus extinguishing the generation source of noise and at the same time retaining the flexibility in the hose.</p> |
