The utility model discloses a metal flexible pipe, including the metal body, metal pipe?inner?wall sets up a detection layer, detection layer includes inlayer and skin, the inlayer is laminated with the inner wall of metal body, outer and inlayer is laminated and is formed an airtight cavity, the interior volatile liquid who packs the dyestuff or have pungent?odor of airtight cavity, by adopting the above technical scheme, when because metal body atress is too big, the inlayer is owing to hug closely with the metal body, so the inlayer also can break along with the metal body, in case and the inlayer breaks, the volatile liquid that packs in the airtight cavity or dyestuff flow out or volatilize a pungent?odor in can following the crack to remind people metal flexible pipe to break, need in time change. 本实用新型公开了种金属软管，包括金属管体，所述金属管体内壁设置检测层，所述检测层包括内层和外层，所述内层与金属管体的内壁贴合，所述外层与内层贴合并形成密闭空腔，所述密闭空腔内填充染料或具有刺激性气味的挥发性液体；通过采用上述技术方案，当由于金属管体受力过大，内层由于与金属管体紧贴，因此内层也会随金属管体破裂，而旦内层破裂，密闭空腔内填充的挥发性液体或染料可以从裂缝中流出或者挥发出刺激性气味，从而提醒人们金属软管破裂
