The fittings can be made of any material compatible with the hose and the media. Some of the most common ones are ilustrated below.

3 Steam or hot oil is circulated through the jacket, which in turn heats the product being conveyed in the core hose. (2) As a cryogenic transfer line. Maintaining a high vacuum in the jacket effectively insulates cryogenic liquids being conveyed in the core hose. EJEMPLOS DE MONTAJES DE MANGUERAS METALICAS1. Avoid Torque: Do not twist the hose assembly during installation when aligning the bolt holes in a flange or in mating up pipe threads. The utilization of lap joint flanges or pipe unions will minimize this condition. It is recommended that two wrenches be used in making the union connection: one to prevent the hose from twisting and the other to tighten the coupling.

4 2. Prevent out-of-plane flexing in an installation: Always install the hose so that the flexing takes place in only one plane -this being the plane in which the bending occurs. 3. Avoid over bending: The repetitive bending of a hose to a radius smaller that the radius listed in the specification tables for corrugated hose will result in early hose failure. Always provide sufficient length to prevent over-bending and to eliminate strain on the hose. 4. Avoid careless handling of the hose assembly: Always lift or carry metal hose to prevent abrasion damage particularly to braided corrugated hose. Store metal hose assemblies away from areas where it can be subjected to spillage, corrosive fumes or sprays, weld splatter, etc.

5 5. Always support the piping: A piping system which utilizes meta hose to absorb movement must be properly anchored and / or guided. Always support the piping to prevent excessive weight from compressing the hose and relaxing the braid tension.
