Frequently Asked Questions
What do I.D., O.D., and R.O.D. mean in these specifications?
I.D. refers to the Inner Diameter of the hose, which determines the flow capacity. O.D. is the Outer Diameter, representing the total thickness including the outer cover. R.O.D. stands for Reinforcement Outer Diameter, which measures the diameter over the reinforcing layer before the final outer cover is applied.
How does the size of the hose affect its Maximum Working Pressure (MAX W.P.)?
Generally, as the hose size (I.D.) increases, the maximum working pressure it can handle decreases. For example, a 5.0 mm (3/16") hose has a maximum working pressure of 415 bar (6020 psi), while a larger 64.0 mm (2 1/2") hose has a maximum working pressure of 70 bar (1015 psi).
What is the safety factor between Working Pressure (W.P.) and Burst Pressure (B.P.)?
The safety ratio between the Minimum Burst Pressure (MIN B.P.) and Maximum Working Pressure (MAX W.P.) is approximately 4:1. For instance, the 10.0 mm hose has a working pressure of 330 bar and a burst pressure of 1320 bar (330 x 4 = 1320).
What is the significance of the Minimum Bend Radius (MIN B.R.)?
The Minimum Bend Radius (MIN B.R.) is the smallest radius to which the hose can be bent without kinking, damaging the reinforcement structure, or restricting fluid flow. Bending the hose below the specified minimum radius (e.g., 90 mm for the 5.0 mm hose) will significantly reduce its service life.
How does the weight of the hose change across different sizes?
The weight per meter increases as the hose size increases due to the additional material required for construction. The weight ranges from 0.27 kg/m for the smallest 5.0 mm hose up to 3.47 kg/m for the 64.0 mm hose.
