The hoses attached to the moving parts may have to …

METAL HOSE - Flexline

Match the liner size to the conveying pipe size and use a larger metal hose assely. If the assely is to be installed in a bent position, reduce the preceding values as follows: 50% for a 90° bend, 25% for a 45° bend, etc. Motion: Besides calculating the correct live length for various classes of motion using the formula at the end of this

Flexible Metal Hoses: An essential guide – What Is Piping

For pressure hoses with braided reinforcement, the corrugation stress comes mainly from the bending of the hose. Therefore, the corrugation stresses can be controlled by setting a limitation on the bending. In other words, the installation is acceptable if the hose is not bent beyond the limiting radius. Similar to the situation discussed in

Formulas for Calculating Bends in Pipe & Conduit

Calculating CLR (Center Line Radius) for Bend Angle. After you’ve selected the appropriate die for bending your pipe, based on the pipe’s outside diameter and wall thickness, you should be able to find the radius of the bend. A simple way to determine the center line radius of a bend of a specific angle is calculate a full circle, then divide that nuer by 360 to find the …

Sheave Size & Wire Rope Strength - The Crosby Group

Bending wire rope reduces its strength. To account for the effect of bend radius on wire rope strength when selecting a sheave, use the table below: Fatigue Life Repeated bending and straightening of wire rope causes a cyclic change of stress called “fatiguing.” Bend radius affects wire rope fatigue life. A comparison of the relative effect of sheave diameter on wire rope …

Bend Allowance Calculator | JMTUSA

Bend allowance is the amount of metal to be added to the total layout. The most important considerations when bending metal is the min. bend radius. When bends are made smaller than the required min. radius, metal will crack at the outside heel of the bend. The min. radius of a bend is determined by the hardness and thickness of the metal.
