Q What do I.D. and O.D. represent in the hose specifications?
I.D. stands for Inner Diameter, which is the measurement of the internal space where fluid flows. O.D. stands for Outer Diameter, which is the measurement of the entire external width of the hose, including the reinforcing layers and cover.
Q How does the PLY rating affect hose performance?
The PLY rating indicates the number of reinforcing fabric layers inside the hose wall. A higher PLY rating (e.g., 4 PLY) generally offers greater strength and structural integrity, helping the hose withstand external forces and maintaining its shape in larger sizes.
Q What is the relationship between MAX WP in bar and psi?
MAX WP represents the Maximum Working Pressure. Both bar and psi are pressure units, where 1 bar is approximately equal to 14.5038 psi. The table provides values in both units for standard industrial reference.
Q Why do some sizes list different standard lengths?
Smaller hose sizes (6mm to 12mm) are typically supplied in 50-meter rolls due to their flexibility and ease of handling. Larger sizes (16mm and above) are standardly packaged in 20-meter or 40-meter lengths to accommodate weight and bending radius limits.
Q Can these hoses be used for high-pressure systems?
The maximum working pressure for these hoses ranges from 12 bar (174 psi) to 20 bar (290 psi) depending on the size. Please ensure your system's operating pressure does not exceed the specified MAX WP for the selected hose diameter.
