According to the production process, the high-pressure oil pipe is mainly divided into high-pressure steel wire weaving oil pipe and high-pressure steel wire surrounding oil pipe.

 

 

 

Steel wire surround rubber tube

 

 

 

The high-pressure steel wire surrounding rubber tube structure is mainly composed of inner rubber layer, middle rubber layer, four or more layers of steel wire reinforcement layer and outer rubber layer.

 

 

 

The inner rubber layer has the effect of making the delivery medium bear the pressure and maintaining the steel wire from corrosion. The outer rubber layer maintains the steel wire from damage. The steel wire (ф 0.3-2.0 reinforcement layer) layer is the skeleton material to enhance the effect.

 

 

 

High pressure steel wire around oil pipe (high pressure oil pipe) use: high pressure steel wire reinforced hydraulic oil pipe is mainly used for mine hydraulic support and oil field development, suitable for engineering construction, lifting and transportation, metallurgy and forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and mechanical and automatic hydraulic system transportation of various industrial departments with certain pressure (high pressure) Oil 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 temperature and liquid transmission, the maximum working pressure resistance can reach 70-120mpa.

 

 

 

Working temperature of high pressure steel wire surrounding oil pipe (high pressure oil pipe): - 40 ℃ ~ 120 ℃

 

 

 

Product standard scale: dn6mm ～ dn305mm.

 

 

 

Type: 4SP type medium pressure rubber tube surrounded by four layers of steel wire.

 

 

 

4sh high pressure rubber tube surrounded by four layers of steel wire.

 

 

 

R12 type four layer steel wire surrounds high temperature and medium pressure oil pipe under severe conditions.

 

 

 

R13 - high temperature and high pressure oil pipe surrounded by multi-layer steel wire under severe conditions.

 

 

 

R15 - high temperature and ultra-high pressure oil pipe surrounded by multi-layer steel wire under severe conditions.

 

 

 

The structure of high pressure steel wire weaving hose is mainly composed of liquid resistant synthetic rubber inner layer, medium rubber layer, I, II, III steel wire weaving layer and weather resistant synthetic rubber outer layer.

 

 

 

However, according to the planning principle of high-pressure hose, layer III woven hose does not have any effect when the hose is under pressure, which wastes the data, increases the weight of the hose itself, and reduces the flexibility of the hose. Therefore, there is no specification of this kind of hose in the specifications of various countries. Some old engineers of enterprises still follow the old norms of the past, so some people still choose this model when planning.

 

 

 

Use of high pressure steel wire weaving hose: high pressure steel wire reinforced hydraulic tubing is mainly used for mine hydraulic support and oil field development, suitable for engineering construction, lifting and transportation, metallurgy and forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, as well as mechanical and automatic hydraulic systems of various industrial departments to transport petroleum base (such as mineral oil) with certain pressure and temperature , soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquid (such as emulsion, oil-water emulsion, water) and liquid transmission.

 

 

 

Working temperature of high pressure steel wire weaving hose: oil -40 ~ 100 C, air -30 to 50 C, water emulsion below +80 C.

 

 

 

Standard scale of high pressure steel wire woven rubber hose: dn5mm ～ dn102mm.

 

 

 

Oil drilling hose

 

 

 

Structure: inner rubber layer, inner rubber maintenance layer, middle rubber layer, steel wire surrounding layer and outer rubber layer.

 

 

 

Use: steel wire surround drilling rubber tube is used for oil field cementing, workover, petroleum geological exploration, small drilling machine, water conservancy mining, mud transportation, normal temperature water and other fluid media.
