What do you mean by "DN" on hydraulic hose?
Hydraulic hose temperature: -40 ~ 120 DEG C, product specification range: DN2.5mm ~ DN305mm.
Hydraulic hose is mainly composed of liquid synthetic rubber, inner rubber layer, middle rubber layer, multi-layer reinforced layer and weather resistant synthetic rubber outer layer. The utility model is mainly used for hydraulic support and oil field development of a mine, and is suitable for engineering, construction, hoisting, transportation and automation hydraulic system to transport medium and water base fluid with certain pressure and temperature.
DN stands for nominal diameter. The standard diameter after standardization, the midpoint between the inner diameter and the outer diameter, in units mm.
