Common size of hose

High-pressure steel wire wound rubber hose: I. specification range of high-pressure rubber hose: dn6mm ~ DN305mm. Type: 4SP - medium pressure hose with four layers of wire wound type 4SH - high pressure hose with four layers of wire wound type R12 - high temperature medium pressure hose with four layers of wire wound type. Type R13 - high temperature and high pressure hose with multilayer steel wire wound under harsh conditions. Type R15 - high temperature and ultra high pressure rubber hose with multilayer steel wire wound under severe conditions. Ii. Characteristics of high-pressure rubber hose 1. The rubber hose is made of special synthetic rubber with excellent heat resistance, oil resistance and aging resistance. 2. High pressure of rubber hose bearing and excellent pulse performance. 3. The rubber hose has excellent bending resistance and fatigue resistance. 4. The pipe is soft, tightly bonded and has little deformation under pressure. 5. The length of the steel wire wound rubber hose is 20 meters, which can be made within 50 meters according to the requirements. Please call for advice before customization. Three, high pressure hose USES: mainly used for mine hydraulic support, oilfield development, suitable for lifting transportation, metallurgy, forging, engineering, construction, mining equipment, injection molding machinery, ships, agricultural machinery, all kinds of machine tools and various industrial departments mechanization, automation has certain pressure in hydraulic system (high pressure) and temperature of oil (such as fuel, mineral oils, soluble oil, hydraulic oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water) and hydraulic transmission, the highest working pressure resistant up to 70-120 mpa. Note: this standard is not suitable for castor oil-based and aliphatic liquids Iv. High-pressure rubber hose structure: high-pressure steel wire wound rubber hose is composed of inner rubber layer, middle rubber lay
