However, according to the design principle of high pressure hose, Ⅲ layer braided hose in the hose pressure can not afford any effect, wasted material, increase the weight of the hose itself, reduce the flexibility of the hose. Therefore, the national standards are not the standard of this hose. Some of the old engineers still use the old standard in the past, so the design is still someone to choose this model.
High-pressure wire braided hose Uses: High-pressure steel wire reinforced hydraulic tubing is mainly used for mine hydraulic support, oil field development, suitable for engineering construction, lifting transport, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and various industries (Such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, water), etc., in a mechanized and automated hydraulic system. Liquid drive.
High-pressure steel wire braided hose Operating temperature: oil -40 ℃ ~ 100 ℃, air -30 ℃ ~ 50 ℃, water emulsion +80 ℃ below.
High pressure steel wire braided hose Specifications range: DN5mm ~ DN102mm.
Oil drilling hose
First, the structure: the inner layer, the inner protective layer, the plastic layer, wire winding layer and the outer layer composition.
Second, use: wire winding drilling hose for oil field cementing, workover and oil geological exploration, small drilling and water mining, transportation mud and room temperature water and other fluid medium.
