High Pressure Rubber Hoses is a type of hose widely used in the industrial field. It has technical characteristics such as high pressure resistance, high wear resistance, and high toughness, and is widely used in industries such as offshore oil, chemical industry, metallurgy, construction, and machinery. This type of hose can withstand harsh conditions such as high pressure, high temperature, and low temperature in extreme environments, and the steel wire weaving design to some extent increases its strength and durability.
The design principle of High Pressure Rubber Hoses is the combination of steel wire layer and adhesive layer, which can withstand greater pressure in high-pressure environments, thereby achieving better stability. At the same time, the steel wire braided hose adopts advanced rubber materials, which enables it to adapt to various harsh working environments, and has good ultraviolet resistance, corrosion resistance, aging resistance and other characteristics.
The main material of high-pressure steel wire woven rubber hose is synthetic rubber and its derivatives, followed by steel wire, which combine to form a high-strength shock absorbing rubber hose. Its product is characterized by excellent oil resistance, corrosion resistance, and wear resistance, which can operate in harsh environments such as high pressure, low pressure, high temperature, and low temperature. Moreover, its inner layer is smooth and will not form scale and dirt in the rubber hose, thereby improving its service life and stability.

coal industry
The oil pipes used in the coal industry mainly include hydraulic support hoses. In recent years, the pressure requirements for some coal mine hydraulic supports have increased, and some steel wire woven rubber hoses cannot meet their performance requirements, requiring the use of steel wire wrapped oil pipes instead. In addition, in order to prevent coal dust pollution during underground coal mining and improve production safety, the variety of oil pipes used in coal mines has been increased, such as the expansion oil pipe of the coal seam water probe hole sealer, which is used for water injection, grouting and other operations on the coal seam before the comprehensive mining of the coal mine underground working face. According to reports, domestic manufacturers have produced and tested it in more than ten coal mines, which can replace similar imported products.
petroleum industry
In the 21st century, China's offshore oil development strategy proposes to focus on developing offshore and shallow oil fields. Therefore, in addition to using drilling oil pipes and vibrating oil pipes, the petroleum industry also requires the use of shallow oil pipelines. Shallow sea subsea oil pipelines have been produced domestically, but floating or semi floating oil pipelines and deep-sea subsea oil pipelines still rely on imports. With the implementation of China's offshore oil development strategy, the requirements for pipeline performance in offshore oil extraction will continue to increase.
High pressure oil pipes are mainly divided into high-pressure steel wire woven oil pipes and high-pressure steel wire wound oil pipes according to the production process.
The high-pressure steel wire wrapped hose structure mainly consists of an inner rubber layer, a middle rubber layer, a four or multi-layer alternating steel wire reinforcement layer, and an outer rubber layer.
The inner adhesive layer has the function of withstanding pressure on the conveying medium and protecting the steel wire from erosion, while the outer adhesive layer protects the steel wire from damage（ ф The 0.3-2.0 reinforcement layer serves as a reinforcing layer for the skeleton material.
The high-pressure steel wire braided hose structure mainly consists of a liquid resistant synthetic rubber inner rubber layer, a middle rubber layer, layers I, II, and III steel wire braided layers, and a weather resistant synthetic rubber outer rubber layer.
But according to the design principle of high-pressure hose, the III layer braided hose does not have any effect when the hose is under pressure, wasting materials, increasing the weight of the hose itself, and reducing the flexibility of the hose. Therefore, there is no standard for this type of hose in the standards of various countries. Some old engineers in enterprises still use the old standards of the past, so some people still choose this model when designing.
High pressure steel wire woven hose usage: High pressure steel wire reinforced hydraulic oil pipes are mainly used for hydraulic supports in mines and oil field development, suitable for engineering construction, lifting and transportation, metallurgical forging and pressing, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanization in various industrial departments In automated hydraulic systems, petroleum based liquids (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, water) with certain pressure and temperature are transported and liquid transmission is carried out.
Working temperature of high pressure steel wire braided hose: oil -40 ℃~100 ℃, air -30 ℃~50 ℃, water lotion+80 ℃ below.
The specification range of high-pressure steel wire braided rubber hose: DN5mm~DN102mm.
Structure: Composed of inner adhesive layer, inner adhesive protective layer, middle adhesive layer, steel wire winding layer, and outer adhesive layer.
Usage: Steel wire wound drilling hose is used for oil field cementing, well repair, petroleum geological exploration, small drilling rigs and hydraulic coal mining, conveying fluid media such as mud and room temperature water.
