Frequently Asked Questions
What do I.D. and O.D. mean in these hose specifications?
I.D. stands for Inner Diameter, which is the measurement of the inside space of the hose cross-section. It determines the flow capacity of the fluid. O.D. stands for Outer Diameter, which measures the entire span of the hose cross-section including the tube, reinforcement, and cover.
What is the difference between Max W.P. and Min B.P.?
Max W.P. (Maximum Working Pressure) is the maximum pressure at which the hose is designed to operate safely during continuous service. Min B.P. (Minimum Burst Pressure) is the pressure at which the hose is tested to fail or burst. Working pressure is typically calculated with a safety factor relative to the burst pressure.
Why is the Min B.R. (Minimum Bend Radius) parameter important?
Min B.R. (Minimum Bend Radius) indicates the smallest radius to which a hose can be bent without kinking, damaging the reinforcement, or restricting flow. Bending the hose beyond this limit can significantly shorten its service life and cause premature failure.
How are the pressure ratings (bar and psi) converted?
The table provides pressure measurements in both bar and psi (pounds per square inch) for international compatibility. 1 bar is approximately equal to 14.5038 psi. For example, a Max W.P. of 207 bar corresponds directly to 3000 psi.
How does the hose size affect its weight and pressure capacity?
Generally, as the inner diameter (I.D.) of the hose increases, the weight per meter increases due to the larger amount of material required. Conversely, the maximum working pressure (Max W.P.) typically decreases for larger diameter hoses to maintain structural safety margins.
