Production of steel wire reinforced hydraulics hoses:
A hydraulic hose is made of a rubber like tube and a reinforcing layer of textile or metal. It’s designed to be robust and withstand the elements of climate and operating conditions.
The reinforcement layer is usually made of a number of layers of wires. Some are coiled and some are braided. The coiled options may be more economical but they tend to untwist when a hose is pressurized, tearing at both the hose core and its cover.
characteristics of steel wire reinforced hydraulic hose
Hydraulic hoses are used to transport hydraulic fluids, including petroleum and biodegradable fluids. They come in a variety of different sizes and styles, depending on the intended application.
They are composed of three main components: a tube and a cover. The tube is the part that actually transports hydraulic fluid, while the reinforcement or strengthening layer helps it withstand external pressures, temperatures, and tension.
The tube is typically made from oil-resistant synthetic rubber, with the reinforced area being made from steel wires that are woven together. The cover can be either a ply, or braided.
The hose’s overall design can also have an impact on its performance. A stainless-steel braided reinforcement with a core made of high-quality, polyurethane will resist temperature and pressure fluctuations better than a braided nylon or nylon hose.
A higher-quality industrial pipe will provide better performance and last longer. This is largely due to the hose’s reinforcement style, which is one of the most important considerations when selecting a hydraulic hose for critical applications.
how to extend the life of steel wire reinforced hydraulic hose
Hydraulic hoses play an important role in hydraulic machinery and systems. It is important to extend their life span in order to ensure smooth operation of your equipment.
Ensure that your hoses are made from high-quality materials and that they are installed properly. This includes examining them regularly for cuts and external wear, replacing them as needed, and addressing any issues that might affect their lifespan.
A good hose will also have a proper pressure resistance rating and temperature resistance. This will help it perform well under consistent pressurization and provide a safe environment for your workers.
Steel wire reinforced hydraulics hoses often have two or more layers made of alternating spiral steel wire, which is then covered with a synthetic rubber. This combination of materials gives these hoses a high degree of pressure and temperature resistance, as well as abrasion and cut resistance.
The reinforcement layer of these hoses may be made of either fiber or stainless steel, with each material having its own impact on the end-use performance characteristics of the hose. For example, a fiber-reinforced braided stainless-steel hose might offer better flexibility and dynamic performance.
The hose pressure is a function the tensile load on the reinforcement layer’s steel wires in a conventional braided pipe. The wires in the reinforcement layer can be heat treated or mechanically treated to influence their E-ratio, for example, by introducing bends into the steel wires.
Steel wire reinforced hydraulic hose wire layer fault
The wire layer fault is one of the most common problems with hydraulic hoses. This is when the reinforcement layer of hydraulic hose shows an irregular or broken wire.
This problem is mainly caused by the high frequency impact of the hydraulic hose, which causes the wire to be deformed unidirectionally. The reinforcing layer appears irregular because the wire breaks around its axis.
If the wire lining is broken along the outer edge of the hose, the cover and hose tube may be damaged. This can lead to a brittleness in the hose that is unable to withstand high pressures.
This can be avoided by adjusting the manufacturing process of a steel wire reinforced hydraulichose. This can be done by adjusting the E-ratio of the reinforcement wires, or preconditioning the hose.
Preconditioning is used to ensure equal loading of wires from different layers across the pressure range. This will ensure that the steel wires behave evenly, which will improve the performance of impulse testing and burst pressure.
The E-ratio of steel wires in the innermost reinforcement layer and outermost reinforcement layer is different. This difference can be reduced by heating them. This way, the tensile strength of each wire is significantly higher than it would have been with a wire with the same tensile strength but with the same E-ratio.
