What do I.D., R.O.D., and O.D. represent in these specifications?
I.D. stands for Inner Diameter, which determines the flow capacity of the hose. R.O.D. stands for Reinforcement Outer Diameter, indicating the diameter over the braided or spiral structural support layers. O.D. stands for Outer Diameter, which is the total outer measurement including the protective cover.
What is the safety factor between MAX W.P. and MIN B.P.?
These hoses feature a high safety factor of approximately 4:1. For instance, while the Maximum Working Pressure (MAX W.P.) is rated at 345 bar (5075 psi), the Minimum Burst Pressure (MIN B.P.) is engineered to withstand up to 1380 bar (20000 psi) before structural failure.
Why is the Minimum Bend Radius (MIN B.R.) important during installation?
The Minimum Bend Radius (MIN B.R.) is the smallest radius to which a hose can be bent without kinking, restricting flow, or placing excessive stress on the reinforcement layers. Bending a hose tighter than the specified limit (ranging from 240mm to 630mm depending on size) will significantly reduce its service life.
How does the hose weight scale with the diameter?
As the inner diameter increases from 3/4" (19.0 mm) to 2" (51.0 mm), the unit weight increases from 1.61 kg/m to 7.20 kg/m. This is due to the larger volume of materials and heavy-duty reinforcement required to maintain the 345 bar pressure rating across larger surface areas.
Are these hoses suitable for high-pressure hydraulic systems?
Yes, with a consistent working pressure of 345 bar (5075 psi) across all sizes from 3/4" to 2", these hoses are specifically designed for high-pressure hydraulic applications, heavy machinery, and demanding industrial fluid transfer processes.
