Installation | Flexible Braided Hoses
INSTALLATION HINTS
To obtain maximum service life from metal hose, two IMPORTANT installation rules must be kept in mind.
2) Avoid Sharp Bends There are many ways a hose can be subjected to recurring sharp bends as a result of improper installation. A few examples are illustrated below. The minimum centerline bend radius for intermittent flexing should never be less than the values specified in the Performance Specifications Section .
1) Do Not Torque A hose is subject to torque by: A) Twisting in installation. To minimize possible torque
damage to a hose, a union or floating flange should be used at one end of the hose assembly. Where flanges are used, the fixed flange end should be bolted into place before the floating flange end. Where a threaded nipple and a union are used, the nipple end should be threaded into place, and then the union tightened into place using two wrenches. B) Twisting on flexure. Always install the hose so that flexing takes place in one plane only, and in the plane of bending.
