Hydraulic hoses are custom designed to meet specific applications. Their inner tube, reinforcements and outer covering all possess distinct qualities that may impact performance.
Hydraulic hoses must be designed and rated to handle the typical working pressures they will encounter, including any surges and peak pressures that might arise during use, to avoid unsafe situations and equipment damage. Failure to do this could prove catastrophic.
High Pressure Hydraulic Hoses
High pressure hydraulic hoses consist of three fundamental parts; an inner tube to carry fluid, an additional reinforced layer and an outer protective sheath. Usually made from thermoplastic or synthetic rubber and designed specifically to carry its chosen fluid type. Once under pressure and tears begin forming in this inner tube reinforcement can help support it under pressure by using braided wire sheathing or spiral wound wire reinforcement woven through braided wire reinforcement sheathings for support and tear resistance.
Steel wire-braided hoses are often employed in applications involving high pressure, such as oilfield equipment. Their extreme durability allows for them to withstand both temperature extremes and high levels of pressure without failing.
When selecting a hydraulic hose, always choose one rated to handle your maximum working pressure. Pay particular attention to psi ratings but also consider any sudden pressure spikes during use that might arise; this will help avoid dangerous situations. Also ensure all component fittings meet this threshold of working pressure.
High Temperature Hydraulic Hoses
Hydraulic hoses designed for use in hot environments must be resistant to both high temperatures and pressure, as thermal exposure can accelerate elastomer and plastic degradation. Switching to high-temperature-rated components may help protect these materials against damage from temperature exposure.
These hoses typically feature an inner tube made from oil-resistant synthetic rubber and one or more steel wire braids for reinforcement, along with an abrasion, ozone, and weather-resistant synthetic rubber cover to provide added abrasion resistance and weatherproofing protection in temperatures ranging from -40F to 212F. They’re intended for use with petroleum-based hydraulic fluids in applications where temperatures don’t go beyond this temperature range.
Industrial settings often call for hydraulic hoses with different properties and uses. Finding the appropriate choice depends on several factors including machine size and capacity as well as working conditions including pressure, temperature and attachment method – you may wish to consult a hose fittings guide or chemical compatibility chart to make an informed choice.
Low Pressure Hydraulic Hoses
Jason Industrial Low Pressure Hydraulic Hoses can be used to transport petroleum-based hydraulic oils, glycol antifreeze, air or water at working pressures below 300Psi (22Bar). A chemical compatibility chart and nomograph will assist in selecting an appropriate size hose hose.
Reinforced hose is designed to maximize strength. A variety of compatible fittings is available to connect it with equipment in the system. Both hose and fitting must meet maximum pressure specifications – connecting 5,000-psi rated hose to fittings that only support 4,500-psi could lead to a dangerous situation.
No matter if it’s low, medium, or high pressure hose, each is made up of the same basic components: cover, reinforcement and tubing that carries hydraulic fluid. What distinguishes each from another lies in its pressure rating (measured in pounds per square inch (psi), temperature requirements and applications.
Custom Hydraulic Hoses
Custom hydraulic hoses offer higher levels of quality than mass-produced generic versions, which may wear out faster. Custom versions are often constructed from more costly materials capable of withstanding higher pressure for extended periods and are tailored specifically to their respective operations so as to fit machines more securely, helping prevent leaks of hydraulic fluid.
Low, medium and high pressure hoses can be divided by their operating (or working) pressure ranges; however, each hose’s burst pressure capabilities depend on both operating pressure as well as burst pressure – typically four times greater.
Hydraulic hoses can be found in various pieces of machinery, such as forklifts and cherry pickers, construction equipment, airport ground service equipment (GSE) and airplane stairs. Their manufacturer can custom fabricate them to meet specific length, size and pressure specifications.
