If it is going to be dispatched immediately after coiling and packing, then the “hose” becomes a product, e.g. solar flex hoses. On the other hand, if it is going to be delivered as a “ flexible hose assembly” it must pass through at least one of the stations mentioned below. During these processes, the semi-finished products are subjected to one or several leakage tests. In other words, each product will have been tested at least times in total without any exceptions.

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.

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

Under the previous title, we stated that the word of &#;quality&#; does not have the same meaning with &#;qualified&#; as we use in daily life and it is rather related to the elements contained in the metal itself. In other words, it refers to material types which come into existence when the elements such as chromium, nickel, molybdenum, etc. in the raw material are available in varying ratios.

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.
