Description

Technical Field

[0002] Hose assembly is a commonly used auxiliary device in hydraulic system, generally composed of liquid-resistant synthetic rubber inner layer, Ⅰ to Ⅵ layers of steel wire braided layer, synthetic rubber outer layer with excellent weather resistance and steel joint. It is used to connect various hydraulic components in hydraulic system, transmit hydraulic power or transport high-pressure media such as water, gas and oil to ensure the circulation of liquid and transmit liquid energy.

[0003] Acid fracturing fire-resistant hose assembly is a key equipment used in oil and gas extraction. It is mainly used to transport high-pressure and highly corrosive liquids in acid fracturing operations. Acidic liquids are used to dissolve minerals in the formation and increase the flow channel of oil and gas; high-pressure liquids are used to fracture the formation, form cracks, and increase oil and gas production. Therefore, there are high requirements for the corrosion resistance, high pressure resistance, and fire resistance of the hose assembly.

[0004] The joints of the hose assembly are generally connected to the hose through a sleeve. When used in a high-pressure environment for a long time, the connection between the sleeve and the hose is prone to loosening, resulting in a loose connection between the joint and the hose, causing leakage of high-pressure acidic liquid and affecting the normal use of the equipment.
