Problems solved by technology

At present, the steel wire wound rubber hose used in oil drilling has poor high pressure resistance and short service life.
The compressive strength of domestic steel wire wound hydraulic rubber hoses is generally low. Some units have also developed ultra-high pressure steel wire wound composite material hoses. Serious research and detailed analysis have not been carried out, and corresponding technical indicators have been formulated. At the same time, the working parameters of the hose production processes have not been strictly regulated, resulting in the working pressure of the ultra-high pressure steel wire wound composite hose. to ultra-high pressure levels

Description

technical field [0001] The invention relates to a rubber hose, in particular to an ultra-high pressure steel wire winding hose capable of withstanding a pressure of up to 50-300 Mpa, and also relates to a preparation method of the rubber hose. Background technique [0002] The hydraulic hose required for oil drilling requires high pressure, and the inner rubber layer of the hose is not compatible with oil. At present, the steel wire wound rubber hose used in oil drilling has poor high pressure resistance and short service life. The compressive strength of domestic steel wire wound hydraulic rubber hoses is generally low. Some units have also developed ultra-high pressure steel wire wound composite material hoses. Serious research and detailed analysis have not been carried out, and corresponding technical indicators have been formulated. At the same time, the working parameters of each process of hose production have not been strictly regulated, resulting in the working pre...
