Large-diameter rubber hose under normal pressure and low pressure
2024-07-25
Large diameter hose according to the working pressure classification can be divided into normal pressure and low pressure:
1. Atmospheric pressure: large diameter hose under atmospheric pressure refers to the hose used to transport gas or liquid under atmospheric pressure. The working pressure of this hose is low, generally below 0. 1MPa, and is suitable for some low-pressure occasions, such as conveying air, water, fuel oil, etc. The normal pressure hose is composed of inner and outer rubber layers and cord or steel wire braid; it has good flexibility and pressure resistance.
Low pressure: the working pressure of large diameter hose under low pressure is generally between 0.1MPa-1MPa, which is suitable for some high pressure occasions, such as conveying hydraulic oil, lubricating oil, fuel oil, etc. Compared with the normal pressure hose. Low pressure hose needs to have better pressure resistance and withstand a certain working pressure. Therefore, it is necessary to choose more pressure-resistant materials and structures, such as synthetic rubber and polyurethane.
