Wire wound hydraulic hose
The structure of high pressure steel wire winding hose is mainly composed of inner rubber layer, middle rubber layer, four or multiple layers of alternately winding steel wire reinforcement layer and outer rubber layer.
The inner rubber layer has the effect of making the conveying medium withstand pressure and protecting the steel wire from erosion, the outer rubber layer protects the steel wire from damage, and the steel wire (Φ0.3-2.0 reinforcement layer) layer is the skeleton material to enhance the effect.
High pressure wire wound hydraulic hose (high pressure hose)
Application: High pressure steel wire reinforced hydraulic hose is mainly used in coal mine and metal mine hydraulic support, oil field development, suitable for construction machinery, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and various industrial departments in the mechanization, automatic hydraulic system transport with a certain pressure (more than the local pressure) and temperature of petroleum base
(such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water) and liquid transmission, the maximum working pressure can reach 70-120Mpa.

Steel wire braided hose
However, according to the design principle of high pressure hose, the Ⅲ layer braided hose does not play any role when the hose is under pressure, wastes material from itself, increases the weight of the hose itself, and reduces the flexibility of the hose. So, each
There is no standard for this kind of hose in the national standard. The old engineers of some enterprises still use the old standards of the past, so some people still choose this model when designing.
Petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquid (such as emulsion, oil-water emulsion, water) with a certain pressure and temperature, and liquid transmission.
High pressure wire braided hose operating temperature: oil -40° C ~ 100 ° C, air -30 ° C ~ 50 ° C, water emulsion +80° C below.
High pressure steel wire braided hose specification range: DN5mm~DN102mm.
Oil drilling hose
Structure: inner rubber layer, inner rubber protective layer, medium rubber layer, wire winding layer and outer rubber layer.
Uses: steel wire wound drilling hose for oil field cementing, repair and petroleum geological exploration, small drilling rig and water conservancy coal mining, conveying mud and normal temperature water and other fluid media.
