Frequently Asked Questions
Q:
What do I.D. and O.D. represent in the hose specifications table?
I.D. stands for Inner Diameter, which determines the flow capacity of the fluid inside the hose. O.D. stands for Outer Diameter, which is critical for determining the external space requirements and selecting correct fittings or clamps.
Q:
What is R.O.D. and why does it matter?
R.O.D. stands for Reinforcement Outer Diameter. It indicates the diameter of the hose over the reinforcement layer (such as steel wire or textile braid) before the outer cover is applied, which is essential for precise fitting crimping specifications.
Q:
How is Working Pressure (MAX W.P.) related to Burst Pressure (MIN B.P.)?
MAX W.P. (Maximum Working Pressure) is the maximum pressure the hose is designed to operate under safely. MIN B.P. (Minimum Burst Pressure) is the safety limit at which the hose will physically rupture. Generally, the burst pressure is rated at 4 times the working pressure to ensure safety.
Q:
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 a hose can be bent without kinking, restricting flow, or damaging the internal reinforcement layers. Operating below this radius can significantly shorten the hose's lifespan.
Q:
How does the hose size affect its pressure rating and weight?
As the hose Inner Diameter (I.D.) increases, the maximum working pressure generally decreases, while the weight per meter (kg/m) increases. This is due to the larger surface area experiencing higher force under pressure, requiring thicker materials.
