This stainless steel flexible pipe is made of a stainless steel sheet, which is metallic, and the material thickness of which is 0.2 - 0.4 mm or less. Furthermore, the stainless steel flexible pipe comprises a pliable section wherein a waveform shape is formed. The waveform shape is such that the ratio d/Dd is 15 -23, where d is the outside diameter (mm) of the basic pipe, and Dd is the depth between the crest and the trough; and that the relational expression d/p = 2.5 - 5.5 is satisfied, where d is the outside diameter of the basic pipe, and p is the crest-to-crest spacing. The stainless steel flexible pipe may comprise a basic pipe section at both ends or one end. A basic pipe section and a pliable section may be alternately disposed in a plurality of places. The whole flexible pipe may have a coiled shape formed by being helically spiraled. The stainless steel flexible pipe may, in addition to comprising a basic pipe section at both ends or one end, comprise a flared section at both ends or one end of the basic pipe section. |
