Frequently Asked Questions
What do the abbreviations I.D., R.O.D., and O.D. stand for?
I.D. stands for Inner Diameter, which is the measurement of the inside space of the hose. R.O.D. refers to Reinforcement Outer Diameter, and O.D. stands for Outer Diameter, which represents the measurement across the entire exterior of the hose.
What is the relationship between MAX W.P. and MIN B.P.?
MAX W.P. (Maximum Working Pressure) is the maximum safe operating pressure for the hose. MIN B.P. (Minimum Burst Pressure) is the pressure at which the hose is expected to fail or burst. In these specifications, the safety factor is 4:1, meaning the burst pressure is four times the working pressure.
Why is the Minimum Bend Radius (MIN B.R.) important?
The Minimum Bend Radius (MIN B.R.) is the smallest radius to which the hose can be bent without kinking, damaging the reinforcement layer, or restricting flow. Bending the hose beyond this limit will significantly reduce its service life and safety margins.
How do pressure ratings change as the hose diameter increases?
Generally, as the hose diameter increases, the maximum working pressure capability decreases. For example, hoses from 3/8" to 1" maintain a working pressure of 276 bar (4000 psi), which drops to 207 bar (3000 psi) at 1 1/4", and further down to 172 bar (2500 psi) for 1 1/2" and 2" sizes.
What units are used to specify weight in this table?
The weight of the hose is specified in kilograms per meter (kg/m). This helps engineers and installers calculate the total weight of the hose assembly for routing and support planning.
