Frequently Asked Questions
1. What does the "Dash" size mean in the specification table?
The Dash size is a standard industry measurement used to identify the inner diameter (I.D.) of a hose in sixteenths of an inch. For example, a -4 dash size represents 4/16", which simplifies to a 1/4" inner diameter.
2. How do I choose the correct Working Pressure (MAX W.P.)?
You should select a hose with a Maximum Working Pressure (MAX W.P.) that meets or exceeds the highest system pressure, including any pressure spikes. According to our table, pressures range from 140 BAR (2030 PSI) for larger sizes up to 420 BAR (6090 PSI) for smaller sizes.
3. What is the safety factor between Working Pressure and Burst Pressure?
The safety factor for these specifications is 4:1. The Minimum Burst Pressure (MIN B.P.) is designed to be four times the Maximum Working Pressure (MAX W.P.) to ensure maximum safety and prevent structural failure under extreme conditions.
4. 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, damaging the reinforcement, or restricting fluid flow. Bending the hose tighter than the specified limit (e.g., 20mm for -2 size, 180mm for -16 size) will significantly reduce its service life.
5. How does the hose weight affect my system design?
Hose weight (measured in KG/M) increases with the hose diameter due to the thicker walls and reinforcement layers required to handle the pressure. Proper routing and support brackets should be planned according to the weight, which ranges from 0.08 kg/m to 0.64 kg/m.
