In situations similar to earthquake in which in addition to thermal expansions / contractions , accessories might be under accidental loads , there shall exist an ability of multidirectional movement absorption and U-type flexible hoses are kinds of best options in such situations U-type flexible hoses allow boilers , chillers , fan coils and other similar systems to move freely in relation to the rest of the structure. U-type flexible hoses are also being used in order to prevent nozzles from cracking or being cut. Flexible hoses are totally applied in different industries like steel , cement , food , petroleum , gas , petrochemical and etc

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

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.

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
