Formula for calculating the length of a metal hose: L = √(R·θ)/90 + L1 + L2 + Z……… Y = 2R(cosθ)………………… L – Length of the hose; R – Radius of curvature; θ – Angle of bending; L1 and L2 – Lengths of the rigid sections (flanges, connectors, etc.); Z – Length over which the hose does not deform, taken as 0.15L; Y – Compensation amount (settlement amount)

Metal hoses have length formulas based on the conditions of use in the field, whereas compensators are designed according to the operating conditions, and their length is not fixed
