Notes of flexible metal hose installation
|Flexible metal hose installation with sharp bend can result in leaking or other failures.|
Flexible metal hoses, especially braided hoses, are often operated under high pressures and convey corrosive or inflammable fluids, such as, petroleum, acids, alkalis and chlorine. The fatigue in the convolutions and corrosion from medias together will account for shortening the life period of the hose. To extend the life span, correct installation is of great importance. There are four points listed below which will assist you with how to install flexible braided hoses correctly and properly.
- No Torque
Torque or twisting will cause premature failure. The resolution recommended is to use two wrenches: one is to prevent the hose from twisting and the other to fix the joints.
- No compression and tension in axial direction
Compression or tension will pose structural damage and accelerate its failure.
- No out-of-plate flexing
Motions of out-of-plate will twist the hose assembly and shorten its service life severely. Keep the hose assembly in one plane so that flexing and bending occurs in the same plane.
- No sharp bends
The minimum bend radius can’t exceed the recommended data of the exact products. Or the sharp bends will cause leakage or other problems.
