Today we are going to share with you guys something basically important about the hydraulic hose.
What Is A Hydraulic Hose?
First, let’s get to know the hydraulic hose definition below:
A hydraulic hose is a hose that can convey the hydraulic fluid to or between hydraulic components. So what components can a hydraulic hose convert for people? The components are valves, tools, and actuators.
And the hydraulic hose is the tube that can be installed with flexibility, and the hydraulic hose pipe is reinforced. And the hydraulic hose is often made of several layers of reinforcement, and this is because the hydraulic pressure hose is widely used for applications with high pressure.
And the hydraulic hose is an important part of any type of hydraulic project system, and it is also important to bend the hydraulic hose with big flexibility. And the hoses can stretch over a long distance.
What Is A Hydraulic Hose Made of?
The hydraulic hose a popular construction material can be applied for multiple uses in the building industry.
And the hydraulic hose is commonly made of fluoropolymers and silicone, elastomers, metal, and thermoplastics. And the composite hydraulic hose or the laminated hose is also popular in the market.
And the hydraulic pressure hose made of rubber material can be designed with excellent elastomeric. So the elastomeric hydraulic hose is really a good option for your requirement if you need strong flexibility. And the texture of the rubber material is much soft, it is much more flexible to bend the hose to any shape while in need.
And the anti-corrosion and chemical resistance is also important to factor when people choose the material of the hydraulic hose because they are exposed all year round. So the material for making a hydraulic hose must be strong enough with high durability.
What Are Hydraulic Hoses Used For
As a matter of fact, the hydraulic hose can be used anywhere, and all types of hydraulic pressure hoses are used for the hydraulic system. The hydraulic hose is a flexible connection between two fluids parts, to convey, transfer the hydraulic fluids to the engine of the machines, vehicles and etc.
The hydraulic hose can be widely used in many places, playing an important role in infrastructure, and the hydraulic hose pipes can be assembled in most mechanical facilities and equipment.
Here are hydraulic hose applications listed below
- Snow and ice trucks, street rollers
- Construction Equipment
- Agricultural equipment
- Petroleum-based fluid equipment
- Mining equipment
- Industrial engineering
- Construction digging tools
- Excavator
- Oil and gas
- Factory applications
- Crane machine
- Others
In a word, the hydraulic hose can be used for equipment, machine, or vehicle which needs heat or power from Petroleum-based fluids, water-based fluids, gas, oil and etc.
Types of Hydraulic Hose
Here are many types of hydraulic hoses, here I introduce some popular hydraulic hose types as follows.
In addition to the reinforced hose, the hydraulic pressure hose can be coiled, convoluted, or corrugated. Reinforced hoses can come in several different materials. Some of those materials include wire helix, textile braid, and wire braid.
A coiled hose is a choice for elasticity and flexibility. This makes the coiled hose expandable as well as easy to store away.
A corrugated hose has pleats (corrugations) or spiral convolutions that increase flexibility. The result is a greater capacity for compression and elongation.
Hydraulic hoses generally fall into two categories: those that comply with SAE standards (the Society of Automotive Engineers) and EN standard hydraulic hoses – the European norm. SAE hydraulics hoses are generally regarded as the industry benchmark and the most widely used within the UK. 16 different types of hose fall within the SAE remit, and each one needs to adhere to strict dimensions and performance characteristics. Here are the main categories:
Braided Hydraulic Hose
The braided hydraulic hose is designed for high-pressure industrial applications, and its reinforcement can come in different layers. 2-wire braided hydraulic hose, 3-wire braided hydraulic hose is the most popular hose pipe in the hydraulic hose industry. You can assemble it to convey petroleum or water-based fluids.
Spiral Hydraulic Hose
Then the spiral hydraulic hose is also the most applied hydraulic hose, consisting of the spiral stainless steel wire as the reinforcement. And the internal configuration of the spiral hydraulic is suitable for heavy-duty construction working with high pulse. Compared with the braided hydraulic hose, the spiral hydraulic hose is less flexible, but with higher strength. You can get the difference between braided hydraulic hose and spiral from us.
Helical Hydraulic Hose
The helical hydraulic hose is a special hydraulic hose, designed with maximum flexibility to achieve the desired function for the hydraulic project. And the helically coiled hydraulic hose can prevent collapse during the working process. Normally, the helical reinforcement is found in the low-pressure suction hose and return line hose.
SAE and EN Standards
Here are two set standards for the hydraulic hose, the SAE standard, and the EN standard:
Manufacturers in the Americans, Australia, and Europe adhere to two sets of quality standards. One is the Society of Automotive Engineers (SAE) J517, and the other is the European Norm (EN) Standards.
SAE Standards
Hydraulic Hose SAE Standard, SAE is the abbreviation of the Society of Automotive Engineers, and SAE standards provide general, dimensional, and performance specifications for the most common hoses widely used in hydraulic systems on mobile and stationary equipment.
SAE is based on the construction technique and material of hydraulic hose. SAE hose standards are the most popular benchmark in the hydraulics industry.
SAE designates these as 100R1 through 100R16. Each style must meet dimensional and performance characteristics, which SAE sets forth.
Meeting SAE standards are voluntary. Having these standards simply assured a similarity across products and different manufacturers.
EN Standards
Hydraulic Hose EN Standard, EN standards evolved from DIN German standards. Asian manufacturers follow these standards as well, but they gravitated toward EN specifications.
Much of this is because the EN-rated hose has a higher pressure rating than the equivalent SAE hose. This provides better safety factors.
Choose the Suitable Hydraulic Hose
Here are many different types of hydraulic pressure hose, and then it’s important to choose the right hydraulic hose, with the right specification, size, length, diameter and etc.
You can choose a durable hydraulic hose for your project installation.
The Dimensions of Hydraulic Hose
Dimensions of the hydraulic hose
The dimensions of the hydraulic hose are the inner diameter and outer diameter, and the I.D of the hydraulic hose is inside. Also, consider the minimum bend radius. The inside diameter, logically, is the inside of the hose or liner.
The outside diameter is a specification for corrugated or pleated hoses.
The minimum bend radius is a combination of two things. The first is the acceptable hose cross-section deformation. The second is the mechanical bending limit of the reinforcement.
Performance Specifications
When choosing a hydraulic pipe or hose, consider the type of fluid that’s conveyed. Also, consider the concentration of that fluid. Then consider any substances or chemicals in that fluid that may erode the hose cover.
The hose you choose must be resistant to any special oils or chemicals that may move through it. And you need to choose the hydraulic hose with high strength, and also with the ability to anti-corrosion properties to the oil, fuel fluid, or any other chemical substances.
Consult with the manufacturer for compatibility specifications.
You now have a rudimentary understanding of how to select the proper hydraulic hose for your needs. Remember that choosing the correct type and grade hose will extend its working life.
What Size Hydraulic Hose Do I Need
There’s no one-size-fits-all answer to determining the perfect hydraulic hose size for your application. Several factors come into play, and it’s crucial to consider them all for optimal performance and safety within your hydraulic system.
Here’s a breakdown of the key aspects to evaluate:
1. Flow Rate:
- This refers to the amount of hydraulic fluid flowing through the hose per unit of time, typically measured in gallons per minute (GPM) or liters per minute (LPM).
- Knowing your system’s required flow rate is essential. You can find this information in the specifications of the hydraulic pump or the device the hose will be feeding.
2. Pressure Rating:
- Hydraulic hoses are designed to withstand specific pressure levels. You need a hose with a pressure rating exceeding the maximum pressure your system will generate to ensure safe operation.
- The pressure rating of your system can be found in the pump specifications or the manufacturer‘s recommendations for the specific attachment you’re using.
3. Hose Length:
- The length of the hose will influence the pressure drop within the system. Longer hoses cause more friction and a slight decrease in pressure at the end of the hose compared to the source.
- Consider using a slightly larger hose diameter for longer runs to minimize pressure loss.
4. Application and Environment:
- The type of equipment and its operating environment can influence hose selection.
- Factors like extreme temperatures, exposure to chemicals, or tight bends might require specific hose materials or construction features.
Here are some resources to help you determine the right hose size:
- Hydraulic Hose Sizing Nomographs: These are charts that can help you visually identify the appropriate hose size based on your flow rate and desired velocity of the fluid within the hose. You can find these online or in hydraulic component supplier catalogs.
- Hydraulic System Manufacturer Recommendations: Consult the user manuals or technical specifications provided by the manufacturer of your hydraulic pump, equipment, or attachment. They might recommend specific hose sizes or types for optimal performance.
- Hydraulic Component Suppliers: These suppliers often have technical staff who can assist you in selecting the correct hose size based on your system requirements.
Important Note: It’s always better to err on the side of caution and choose a hose with a higher pressure rating and slightly larger diameter than the minimum requirement. This provides a safety buffer and helps minimize pressure loss due to hose length.
Remember, safety is paramount when dealing with hydraulic systems. Never use a hose that is not rated for the pressure and flow of your specific application. If you’re unsure about the proper hose size selection, consult a qualified hydraulics professional for guidance.
