The quality of the hydraulic rubber hose is directly related to the safety of the use. So it is very important that how to determine whether the quality of the high-pressure pipe hose is qualified.

High-pressure rubber hose usually consists of four layers: outer rubber layer, steel wire reinforcement layer, middle rubber layer, and inner rubber layer.

1. The inner rubber layer directly touches the hydraulic oil, usually made of synthetic rubber.

2. The bearing capacity of the flexible hose depends on the reinforcement layer. This layer is the skeleton of the hose pipe, which is usually woven or wound with steel wire.

3. Most medium and high pressure use steel wire woven body as the skeleton, and high pressure and super high pressure mostly use the steel wire to surround the skeleton.

4. The outer rubber layer is usually made of abrasion-resistant and corrosion-resistant rubber to ensure that the reinforcement layer is not subject to mechanical damage, chemical corrosion, wet rust. Used for oil return pipeline.
