Frequently Asked Questions
What do I.D. and O.D. represent in the specifications?
I.D. stands for Inner Diameter, which is the internal measurement of the hose. O.D. stands for Outer Diameter, which is the measurement of the entire exterior cross-section. Both are crucial for determining compatibility with fittings and installation spaces.
What is R.O.D. and why does it matter?
R.O.D. stands for Reinforcement Outer Diameter. It indicates the diameter over the reinforcement layer (such as steel wire or textile braid) before the final outer cover is applied. This measurement is key for crimping and selecting the correct sleeve or ferrule.
How does Maximum Working Pressure (MAX W.P.) differ from Minimum Burst Pressure (MIN B.P.)?
MAX W.P. (Working Pressure) is the maximum pressure the hose can safely handle during continuous operation. MIN B.P. (Burst Pressure) is the threshold pressure at which the hose will physically fail or rupture. The burst pressure is designed with a safety factor, typically 4 times the working pressure.
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 internal reinforcement, or restricting fluid flow. Bending the hose tighter than the specified MIN B.R. can significantly reduce its service life.
Why do pressure ratings decrease as the hose diameter increases?
As the Inner Diameter (I.D.) of a hose increases, the internal surface area increases. According to fluid dynamics, this larger surface area experiences greater total force at the same pressure, requiring lower working pressure limits to maintain structural integrity.
How is the weight of the hose calculated in the table?
The weight is listed in kilograms per meter (kg/m). This helps engineers and logistics teams calculate the overall weight of the hose assembly for shipping, support bracket planning, and dynamic system loads.
