Product Features and Application Scope of High-Pressure Steel-Wire-Braided Rubber Hoses The structure of a high-pressure steel-wire-braided rubber hose consists of an inner rubber layer made of liquid‑resistant synthetic rubber, an intermediate rubber layer, one or more layers of steel‑wire braided reinforcement, and an outer rubber layer with excellent weather‑resistance properties.

　　 High-pressure steel-wire-reinforced rubber hose The structure consists of a liquid‑resistant synthetic rubber inner liner, an intermediate rubber layer, one or two or three layers of steel‑wire braided reinforcement, and an outer rubber layer with excellent weather‑resistance properties.

　　Product Features:

　　1. The hose is manufactured using a specially formulated rubber compound, offering excellent oil resistance, heat resistance, and aging resistance.

　　2. The hose exhibits high pressure resistance and superior pulse performance.

　　3. The pipe body is tightly connected, flexible in use, and exhibits minimal deformation under pressure.

　　4. The hose exhibits excellent resistance to flexing and fatigue.

　　5. Steel‑wire‑reinforced hoses are available in long lengths: for diameters of 32 mm and above, the standard fixed length is 20 meters; for diameters of 25 mm and below, continuous lengths can reach ten meters or even exceed one hundred meters.

　　Operating temperature: oils, −40°C to +100°C; air, −30°C to +50°C; water-based emulsions, below +80°C.

　　Product usage:

　　Steel‑wire‑reinforced hydraulic rubber hoses are primarily used in mine hydraulic supports and oilfield drilling, and are suitable for engineering construction, lifting and conveying, metallurgical forging and pressing, mining equipment, marine applications, injection molding machinery, agricultural machinery, various machine tools, as well as mechanized and automated hydraulic systems across diverse industrial sectors. They are designed to convey petroleum‑based fluids (such as mineral oil, soluble oil, hydraulic oil, fuel oil, and lubricating oil), water‑based fluids (such as emulsions, oil‑water emulsions, and water), gases, and other media under specified pressure and temperature conditions, and are also employed in fluid power transmission systems.

　　Inspection and Maintenance of High-Pressure Steel-Wire-Braided Rubber Hoses During Operation

　　After a period of use, the high-pressure steel-wire‑reinforced hose assembly should be inspected and maintained regularly. The inspection items are as follows:

　　1. During the assembly of high-pressure wire‑braided hoses, verify that the bending radius meets the specified requirements and that the hose is not distorted. A bending radius that is too small or kinking can accelerate damage to the hose or cause connections to loosen.

　　2. Check the operating temperature of the pipe body; if a temperature rise is detected, promptly inspect the hydraulic system and implement appropriate cooling measures.

　　3. Inspect the hydraulic hoses for external damage; ensure there is no rupture or oil leakage on the outer rubber, and that the fittings show no signs of damage or oil leakage.

　　During operation, be sure to avoid over‑tightening or abrupt turning of the valve stem; otherwise, it may result in… High-pressure steel-wire-reinforced rubber hose Bursting may occur; to prevent damage to high-pressure hoses and restriction of flow, the bending radius of high-pressure wire‑braided hoses should be maximized. Additionally, when routing high-pressure hoses between components, sufficient clearance should be provided to avoid contact or friction during operation. Protective measures can also be implemented—such as installing spring guards, protective sleeves, and other accessories—to ensure the proper functioning of the hydraulic hose assembly.
