Types of High Pressure Hydraulic Hose
SAE standard hydraulic hoses are some of the most commonly used hoses out there. The standard ranges from R1 to R18, each defining the construction of the hydraulic hose. The standard defines what material the inner tubing is made from so that you choose the correct one for fluid compatibility and operating temperature. It also tells you how many layers of reinforcement are there and what material they're made from to give you an idea of the level of pressure it can withstand.
The SAE 100R4 and 100R6 are commonly used for low-pressure applications like return lines, anti-static lines, and vacuum applications. It is for this reason that they are low-pressure hoses with a layer or layers of braided textile fibers. Depending on the pressure, it may require a spiral of steel wire as well. Typically, they are suitable for petroleum and water-based hydraulic fluids and are small enough to be routed easily.
Thermoplastic refers to the inner tubing material used. What sets it apart from its rubber counterpart is that for the same inner diameter, a thinner inner tubing polymer material is required that is more flexible, durable, easy to construct, and works great in low-temperature conditions. The SAE 100R7, R8, and R18 define the construction of this type of hydraulic hose.
Spiral steel wire hydraulic hoses are used for applications that require higher than normal pressures and superior resistance to flexing like heavy-duty machinery used in agriculture, logging, or mining. What makes R13 so suitable for high-pressure applications is the high number (minimum 4) of reinforcement braids used in its construction. Additionally, they are separated by a ply layer running in opposite directions to ensure adhesion between each layer, including the inner tube and the cover.
Application of High Pressure Hydraulic Hose
Construction
From excavators to cranes, high pressure hydraulic hose are used extensively in construction equipment. They help with tasks like lifting heavy loads, operating attachments, and controlling movements.
Agriculture
In the agricultural sector, high pressure hydraulic hose find application in machinery such as tractors, harvesters, and sprayers. These hoses enable precise control over functions like steering, lifting implements, and regulating fluid flow.
Manufacturing
Hydraulic systems play a vital role in manufacturing processes that require precise force or pressure control. Whether it's operating presses or molding machines, high pressure hydraulic hose provide the necessary power transmission.
Automotive industry
Hydraulic brake systems rely on specialized high-pressure hoses to distribute brake fluid from the master cylinder to each wheel's brakes effectively.
Mining
The mining industry requires robust equipment capable of handling extreme conditions while ensuring safety and efficiency. Hydraulic-powered machinery is commonly employed for drilling rigs, loaders, haul trucks-all using high pressure hydraulic hose for their operation.
Marine sector
In marine applications such as ships' steering mechanisms or offshore oil rig operations ,high pressure hydraulic hose plays an important role due to its durability, resistance against corrosion and ability to withstand harsh environments .
Components of High Pressure Hydraulic Hose
Inner lining
The internal part of the hose is typically a plastic or rubber inner lining which houses the hydraulic fluid. The material chosen will depend on the type of fluid that it will contain, in order to guarantee compatibility and avoid corrosion.
Outer layer
The third layer of a hydraulic hose is a protective cover that protects the hose against damage from external sources such as the environment, wear and abrasion. The outer layer is made from a rigid yet flexible material which ensures the integrity of the fluid is contained without impacting the operations.
Reinforcement
The inner lining is encased in a coiled or braided wire reinforcement layer to provide support and enable the hose to withstand both internal and external pressure.
Hose end fittings
A crucial part of any hydraulic hose assembly. Hose end fittings are essential for holding and directing the flow of fluid, preventing leaks, maintaining specified pressure inside the hose and securely connecting the hose to other components in the hydraulic system such as cylinders, valves and pumps.
How to Choose High Pressure Hydraulic Hose
Firstly, consider the pressure rating of the hydraulic hose
This is perhaps one of the most important factors to consider as it determines the maximum pressure that the hose can handle. It is essential to choose a hose with a pressure rating that exceeds or matches the maximum operating pressure of your hydraulic system.
Secondly, take into account the compatibility of materials
Hydraulic hoses are typically made from different materials such as rubber, thermoplastic, or synthetic fibers. It is crucial to ensure that both the inner tube and outer cover material are compatible with the fluid being conveyed in your hydraulic system. Chemical compatibility should also be considered if there are any specific fluids or chemicals involved.
Next, evaluate factors such as temperature range and flexibility
High-pressure hydraulic hoses may be subjected to extreme temperatures and need to withstand these conditions without compromising performance. Ensure that you select a hose with an appropriate temperature range suitable for your application.
Don't overlook industry standards and certification
Lastly, don't overlook industry standards and certifications when selecting a high-pressure hydraulic hose. Look for hoses that comply with recognized standards such as sae (society of automotive engineers) or iso (international organization for standardization). These certifications ensure that the hoses meet stringent quality and performance standards.
Preparation of raw materials (synthetic rubber and stainless steel wire)
At the beginning of the manufacturing process of hydraulic hoses, we need to prepare all the raw materials in advance, in this case synthetic rubber material and stainless steel wire. You can find out what hydraulic hoses are made of by clicking here. We will prepare enough raw rubber material in the hydraulic hose manufacturer's workshop.
Manufacture of reinforcement-braiding or spiral process.
Now we prepare stainless steel wire to make the reinforcing layer of the hydraulic hose. There are two different ways to manufacture the stainless steel reinforcement layer, so we can make two types of hydraulic hoses in this step: braided hydraulic hoses and spiral hydraulic hoses.
Extruding Inner Rubber
Extruding synthetic rubber to create an inner tube with a smooth surface and uniform thickness.Now it's time to make the inner tube of the hydraulic hose. We use a rubber extruder to extrude the rubber material to create the inner tube.This is the steel rod in the rubber extruder that is used to extrude the empty hose. The diameter of the steel rod is equal to the inner diameter of the finished hydraulic hose.After the extrusion process, we get the inner tube of the hydraulic hose, which has a smooth surface and looks shiny.
Print Private Label
In this step, we can customize the surface of the hydraulic hose cover with your own label or hose company logo. All hydraulic hose specifications and your brand name will be printed on the surface of the hydraulic hose lay line.
How to Maintain High Pressure Hydraulic Hose
Regular inspections
Routinely inspect your high pressure hydraulic hose for any signs of wear, damage, or leakage. Look out for cracks, bulges, abrasions, or loose fittings. Early detection can prevent major issues down the line.
Cleanliness
Keep your high pressure hydraulic hose clean from dirt, debris, oil, and other contaminants that can cause damage or clog the system. Use a mild detergent solution to gently clean the hoses when necessary.
Correct storage
When not in use, store high pressure hydraulic hose properly in a clean and dry environment away from direct sunlight or extreme temperatures. Avoid sharp edges or objects that can puncture or cut the hose.
Proper handling
Handle high pressure hydraulic hose with care to avoid unnecessary stress on them. Avoid bending them beyond their specified minimum bend radius as it can lead to internal damage.
Maintain proper pressure levels
Ensure that you are using the correct pressure levels within the recommended range for your specific application. Excessive pressure can cause hose failure while insufficient pressure may result in inefficient performance.
Timely replacement
Replace worn-out or damaged high pressure hydraulic hose promptly before they fail completely and cause costly downtime.
