The end pieces of flexible hose fittings such as nipple, coupling/sleeve (usage with union nut), nut, etc. can be manufactured from materials such as stainless steel, carbon steel, chrome coated, brass, chrome coated brass, etc. in conformity with TS EN standards as desired or stipulated by the standard. In the nonstandard application, the right material selection by user/manufacturer is important such as in the hose.

Flexible hoses are made of a thin stainless steel band formed as a tube , seamed by longitudinal welding and finally corrugated with convoluted profiles . It means that each corrugation is perpendicular to the pipe centerline and its movement is independent from other corrugations . We call them &#;low pitch&#; when corrugations are positioned too close to each other and &#;high pitch&#; when they are a little bit farther from each other

For situations in which we need more bending flexibility, hoses with Ω shaped corrugations are applied that for the sake of increasing number of convolutions per unit length without thickness reduction of the bellows plate, they benefit from a longer lifetime in bend loadings. This type of flexible hose tends to return to its initial form when released from loading and also they are appropriate for vacuum situation. Ω shaped corrugations are more pressure resistant as well

Flexible hoses provide ease of installation and use, as well as corrosion resistance. They can convey fluids such as natural gas and hot/cold water. Stainless steel hoses are manufactured in compliance with the standards of TSE and EN ISO and undergo specific tests. Manufacturers receive certification for products that pass these tests, and customers are advised to pay attention to these certifications.

ENETAF SANE metal flexible hoses are kinds of flexible joints made of stainless steel which are applied with the purpose of eliminating vibrations generally on non-planar piping paths.Furthermore, they are useable in misaligned piping. They have upper most level of flexibility and pressure , internal corrosion and external abrasion resistance . Flexible hoses are made of a bellows as well as one or more layers of braids.  The metal  flexible hose  can be welded , flange type , male threaded and union nut type
