Detailed Explanation of the Characteristics and Application Scope of High-Pressure Steel-Wire-Braided Rubber Hose Assemblies

　　 High-Pressure Steel Wire Braided Rubber Hose Assembly The structure consists of a liquid‑resistant synthetic rubber inner liner, an intermediate rubber layer, a steel‑wire braided reinforcement layer of Type I, Type II, or Type III, and an outer rubber layer with excellent weather‑resistance properties.

　　I. Characteristics of High-Pressure Steel-Wire-Braided Rubber Hose Assemblies:

　　1. Formulated from a specially compounded rubber, it exhibits excellent oil resistance, heat resistance, and aging resistance.

　　2. High bearing pressure and excellent pulse performance.

　　3. The material exhibits tight interfacial bonding, high flexibility, and minimal deformation under pressure.

　　4. Internal curvature and fatigue resistance.

　　5. The wire‑braided flexible hose is available in long lengths: models with a nominal diameter of 32 mm or greater can be connected up to 20 meters, while those below 25 mm can be connected up to 10 meters; lengths exceeding 100 meters are also offered.

　　6. Operating temperature: oil –40 to 100°C, air –30 to 50°C, water-based emulsions below 80°C. Please select products specifically designed for use with this manufacturer’s equipment.

　　II. Applications of High-Pressure Steel-Wire-Braided Rubber Hose Assemblies:

　　 High-Pressure Steel Wire Braided Rubber Hose Assembly It is primarily used in hydraulic supports for mining, oilfield extraction, construction projects, lifting and transportation, metallurgical forging, mining equipment, shipbuilding, injection molding machinery, agriculture, various machine tools, and mechanized and automated hydraulic systems across diverse industrial sectors—serving as a petroleum‑based fluid under specified pressure and temperature conditions.

　　III. Precautions for the Use of High-Pressure Steel-Wire-Braided Hose Assemblies

　　1. High temperature, High-Pressure Steel Wire Braided Rubber Hose Assembly Its service life is shortened at high ambient temperatures; therefore, keep it as far away from heat sources as possible. When necessary, use a protective hose sleeve or install thermal insulation panels to prevent excessive heating of the hose under high‑temperature conditions.

　　2. Prevent surface friction: During installation and operation, avoid contact with other pipelines to prevent friction‑induced rupture. If cross‑over or operational friction is unavoidable, use protective devices such as hose clamps or springs.

　　3. Bending: The minimum bending radius for emergency applications is R = (9–10)D, where D is the hose’s outer diameter. Bending should be avoided at a radius of less than six times the hose’s outer diameter between the fitting and the straight‑to‑curved transition section.

　　4. When installing high-pressure steel‑wire‑reinforced hoses, do not overtighten during installation; allow for a sufficient length of slack. Ensure that there is no relative movement at either end, and maintain the hose’s natural sag. After compression, the hose’s length and diameter will change; consequently, when stretched, the hose expands under pressure, leading to a reduction in its strength.

　　5. During installation, avoid deforming the hose; even slight kinking can reduce its strength or cause fittings to loosen.

　　6. The hose bend and the hose fittings should be installed on the same plane to prevent twisting. In particular, if the connectors at both ends of the hose lie in two different planes, install clamps at appropriate locations and divide the hose into two sections, ensuring that each section lies in the same plane.

　　7. If the key components are equipped with hoses, it is recommended to inspect or replace them regularly.

　　Assess whether the product quality has reached proper vulcanization, and determine whether it exhibits under‑vulcanization or over‑vulcanization. Improper vulcanization during production can result in substandard product performance, uneven rubber wall thickness, and adverse effects on the inner rubber layer.
