Bending radius

How to define the bending radius

Bending radius: "R" is the radius of the smallest possible circle, to which a hose in service can be bent without damage or shortening its lifetime, by kinking. Textile reinforced hose may kink if the bending radius is reduced. A helical wire will serve for a better bending radius without flattening or kinking.

Mandrel-built hoses
6 x inside diameter

Spiral reinforced hoses (in/outside smooth)
8 x inside diameter till 100 mm diameter
10 x inside diameter over 100 mm diameter

Spiral reinforced hoses (outside welded)
6 x inside diameter till 100 mm diameter
8 x inside diameter over 100 mm diameter

When hoses under pressure please calculate 4/5 of the above mentioned figures. The bending radius depends highly on the structure and assemblies of the hoses.
