What are the characteristics of high-pressure steel-wire-reinforced rubber hoses?

　　High-pressure hoses are classified into high-pressure steel-wire braided hoses and High-pressure steel-wire-reinforced rubber hose Next, let’s take a look at their characteristics.

　　Microstructure of high-pressure steel-wire braided hoses:

　　1. Structural type of high-pressure steel-wire-braided rubber hoses:

　　It is primarily composed of an inner rubber layer made of liquid‑resistant synthetic rubber, a middle rubber layer, one, two, or three layers of steel wire braiding, and an outer rubber layer of weather‑resistant synthetic rubber. The inner rubber layer enables the conveyed medium to withstand pressure while protecting the steel wires from corrosion. The outer rubber layer safeguards the steel wires against damage. The steel wire layers serve as the reinforcing skeleton, providing structural integrity.

　　2. Operating temperature:

　　For oil at temperatures ranging from –40°C to +100°C, for air at –30°C to +50°C, and for water-based emulsions below +80°C, please use our specialized products.

　　3. Product Specifications:

　　Large bending radius: 1280 mm–90 mm. Technical specifications for single-layer steel-wire-braided rubber hoses.

　　 High-pressure steel-wire-reinforced rubber hose Microstructure:

　　1. Structural Type of High-Pressure Steel-Wire-Braided Rubber Hose

　　It is primarily composed of an inner liquid‑resistant rubber layer, a middle rubber layer, two, four, or six layers of steel wire winding for reinforcement, and an outer rubber layer. The inner rubber layer enables the conveyed medium to withstand pressure while protecting the steel wires from corrosion. The outer rubber layer safeguards the steel wires from damage, and the steel wire layer (with wire diameters ranging from 0.3 to 2.0 mm) serves as the reinforcing skeletal structure.

　　Product specification range: DN6 mm to DN305 mm.

　　2. Characteristics of High-Pressure Wire-Braided Rubber Hoses

　　The hose is made of a special synthetic rubber, offering excellent oil resistance, heat resistance, and aging resistance.

　　Rubber hoses exhibit high pressure ratings and excellent pulse‑resistance performance.

　　The tube body is tightly bonded, feels soft to the touch, and exhibits minimal deformation under pressure.

　　This hose exhibits excellent resistance to bending and fatigue.

　　Our factory typically manufactures steel-wire-reinforced rubber hoses in lengths of 20 meters, with custom lengths available up to 60 meters upon request.

　　3. Operating temperature: -40°C to 120°C

　　It is widely used in many fields:

　　High-pressure steel‑wire‑reinforced hydraulic hoses are primarily used in mining hydraulic supports and oilfield extraction. They are suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, marine applications, injection molding machinery, agricultural machinery, as well as various machine tools and mechanized automated hydraulic systems across industrial sectors, conveying petroleum‑based fluids (such as mineral oil, soluble oil, hydraulic oil, fuel oil, and lubricating oil) and water‑based fluids (such as emulsions, oil‑water emulsions, and water) under specified pressure (including higher pressures) and temperature conditions. These hoses can withstand working pressures of up to 70–100 MPa.

　　 High-pressure steel-wire-reinforced rubber hose Pressure Intensity Testing Equipment:

　　1. Product Introduction

　　The Jinan Simite pressure‑resistance testing equipment for braided, wrapped, knitted, and short‑fiber hoses is primarily used to conduct pressure‑resistance tests on these types of hoses. The system features touch‑screen control and a multi‑station design, enhancing operator efficiency. After testing is complete, the unit is purged and drained.

　　2. Characteristics of the Pressure-Resistance Testing Equipment for High-Pressure Steel-Wire-Braided Rubber Hoses

　　The pipeline maintains pressure in a single, consistent manner. During testing, if a leak is detected, the alarm will automatically trigger an alert, and the test data can be stored or exported to a computer for analysis. The multi‑station design enhances testing efficiency.

　　The system can monitor the entire testing process in real time, automatically record test data, and print the results as data tables or graphs. It features manual operation, automatic operation, automatic shutdown upon system overpressure, and an unloading alarm function.
