 High pressure rubber hose

 

I  Structure of high pressure rubber hose

high pressure rubber hose is composed of inner rubber layer, middle rubber layer, reinforced layer with steel wire braided or wined, and outer layer of synthetic rubber which has excellent resistance to weather.

 

 

II  Application of high pressure rubber hose

mainly used to mine hydraulic support, oilfield exploitation, suitable for building engineering, hoisting and conveying, metallurgy forging, mining equipment, ships, plastic injection machinery, agricultural machinery, various types of machine tools and various mechanization, automation hydraulic system of industrial sectors to convey oil base liquid with a certain pressure and temperature (such as mineral oil, soluble oil, hydraulic oil, fuel, lubricating oil) , water-based liquids (such as emulsion, oil and water emulsion, water), gas and liquid transmission.

 

III  Temperature of high pressure rubber hose

Oil:  -40桪+100,

Air:  -30桪+50 ,

water emulsion:  below 80,

If these values are exceeded, please select our companies products.

 

IV  Characteristics of high pressure rubber hose

1. rubber hose is made of special synthetic rubber with excellent oil resistance, heat resistance and aging resistance.

2. rubber hose can bear high pressure and pulse performance is superior.

3. the pipe body is combined tightly, soft to use, small deformation under pressure.

4. rubber hose has excellent flexibility and fatigue resistance.

5. length of wire braided rubber hose: the fixed length of 32 rubber hose is 40 meters, the fixed length of diameter below 25 can be 50 meters, the small size can be up to 100 meters.

 

V  Classification of high pressure rubber hose

1. according to the materials

(1)rubber material

(2)rubber and plastic material

2. according to the production process

(1)steel wire braided rubber hose

high pressure wire braided hose: high-pressure steel wire reinforced hydraulic oil pipe is mainly used for mine hydraulic support, oilfield development, and is suitable for in building engineering, lifting transport, metallurgy forging, mining equipment, ships, injection molding machinery, agricultural machinery, various types of machine tools and various industrial sectors mechanization, automation hydraulic system conveying with certain pressure and temperature of oil base (such as mineral oil, soluble oil, hydraulic oil, fuel, lubricating oil) and water-based liquids (such as emulsion, oil and water emulsion, water) and liquid transmission.

 

 

(2)steel wire winded rubber hose

High-pressure steel wire winded oil tube (high-pressure oil pipe): high pressure wire reinforced hydraulic oil pipe is mainly used for mine hydraulic support, oilfield exploitation, is suitable for building engineering, lifting transport, metallurgy forging, mining equipment, ships, injection molding machinery, agricultural machinery, machine tools and various industrial departments mechanization, mechanization, automation hydraulic system of industrial sectors to convey oil base liquid with a certain pressure and temperature (such as mineral oil, soluble oil, hydraulic oil, fuel, lubricating oil) , water-based liquids (such as emulsion, oil and water emulsion, water), gas and liquid transmission, the highest resistance to working pressure reach to 70-120Mpa.

Working parameters of high pressure steel wire winded hose:

Operating temperature: -40120 ;

Product specification range: DN6mm ~ DN305mm.

Types

Type 4SP - four layer steel wire winded medium pressure hose

Type 4SH - four layers of steel wire wrapped high pressure hose

Type R12 - four layers of steel wire winded high temperature medium pressure hose under harsh condition.

Type R13 multi - layer steel wire winded high temperature and high pressure rubber hose under harsh condition.

Type R15 multi-layer steel wire winded high temperature and super high pressure rubber hose under harsh condition.

(3) thread wire braided rubber hose

(4)fabric rubber hose.

fabric hose is widely used in industrial and agricultural machinery and equipment, according to the different transport medium, various types of fabric hose is a flexible hose that used to transport (positive and negative pressure condition)various of liquid viscous fluid and solid powder and other materials medium.

 

 

3. according to the usage and the use of materials and the degree of different pressure

(1)Micro oil resistant high pressure hose. It mainly uses in the coal mine hydraulic support, the amount of using is particularly large, some large mines, the amount of a year reach to tens of millions. This is a lot of industry can not match, in the usual work, if it is a big task, then in the warehouse can see there are a lot of high-pressure hose, looks like a hill heap. Especially large caliber winded rubber hose, demand is great, and in high pressure hose industry its price is also expensive. Secondly, used in agricultural equipment with very low practical performance,using amount of these devices is large, but the performance requirements are very low.

(2)high-pressure hose with high oil resistance, which is mainly used in mechanical engineering, the using strength is large, frequency is high. Requirements of stress corrosion resistance is high. Many of the mobile machinery especially excavators, is particularly evident, now can be seen everywhere. Not only that, the size of the excavator is more and more big, the pursuit of high work intensity is also a tend of increasingly, heavy, frequency.

 

VI  Specification range of rubber hose: DN2.5mm ~ DN305mm.

1. rubber hose and hose assembly can only be used to convey the designed materials, otherwise it will reduce the service life or invalid.

2. use the length of rubber hose, length change of rubber hose in high pressure (-4%-+2%) and the length change caused by mechanical movement correctly.

3. the using pressure of rubber hose and hose assembly should not be more than the designed working pressure (including impact pressure).

4. under normal circumstances the media temperature conveyed by rubber hose and rubber hose assembly, should not exceed -40 -+120, otherwise it will reduce the service life.

5. rubber hose and hose assembly should not be used in the condition that less than the minimum bending radius of rubber hose, avoid happening bend or flex near the pipe joint, otherwise it will hinder the hydraulic transmission and transportation of materials or damage rubber hose assembly.

6. rubber hose and hose assembly, should not be used in torsion state.

7. rubber hose and hose assemblies should be carefully carried, should not drag and drop on the sharp and rough surface, should not bend and squash.

8. rubber hose and hose assembly should keep clean, the internal should be washed cleanly (especially acid conveying pipe, spray pipe, mortar tube). Prevent foreign objects entering into the lumen and hinder conveying fluid, damage the device.

9. the rubber hose and hose assembly exceeds service deadline or storage period can continue to use after the experiment was carried out to identify.
