Multi-flex stainless steel roof drain hose

摘要

A drain hose that connects to the movable roof of a petroleum storage tank. The hose extends downwardly through the material stored in the tank and to a discharge at the lower portion of the tank. The hose is comprised of (a) an inner stainless steel tube(or hose) having a stainless steel over-braid and (b) a spirally wound outer tube (or hose) also of stainless steel. The inner hose is connected to flanges that have ferrules extending therefrom. The outer protective hose is captured in a free floating manner by the ferrules such that the outer hose is allowed to move along or slide over the inner hose without escaping the end ferrules.
