Mining high-pressure hose and engineering high-pressure hose is also a high-pressure hose, the essence of the difference is not much, all play the role of oil pressure.

But there are differences in the degree of functionality between the two, first of all, mining high-pressure hose oil resistance is poor, because the resistance is emulsion, emulsion is oil and water to a certain ratio of configuration, in addition to adding some anti-wear rust lubrication chemical composition.

The engineering high-pressure tubing oil resistance is relatively strong, many places are straight to call this kind of engineering high-pressure tubing for the oil pipe, visible in its main conveyor is an oil medium. As a result of the above differences, mining high-pressure oil hose relative to the engineering high-pressure oil hose rubber content is relatively low, poor oil resistance.

Secondly, the two outer rubber layer properties require different focus. Mining high-pressure hose focus on anti-static, flame retardant function. Because under the coal mine, do not allow high pressure hose with static load, can not accumulate static load, but the accumulation, it is easy to produce electric sparks, which in turn cause an explosion. Engineering high-pressure fuel hose is mostly used for outdoor work, so focus on resistance to harsh climate.

Rubber hose is divided into two kinds of high-pressure hose and low-pressure hose, high-pressure hose is generally composed of four parts: outer rubber layer, steel wire reinforcement layer, middle rubber layer and inner rubber layer. The inner rubber layer of the hose is in direct contact with the hydraulic oil, generally made of synthetic rubber. The bearing capacity of the hose depends on the strengthening layer, the layer is the skeleton of the hose, usually made of steel wire braid or winding. Most of the high-pressure steel wire braid for the skeleton, high-pressure, high-pressure steel wire winding skeleton. The outer rubber layer of the hose is generally made of wear-resistant, corrosion-resistant rubber to ensure that the reinforcing layer is not subject to mechanical damage, chemical corrosion, moisture rust, low-pressure hose to braided cotton, hemp wire instead of braided steel wire, generally used for low-pressure oil return pipeline.
