Today we are going to share with you guys something basically important about the hydraulic hose.

What Is A Hydraulic Hose?

At 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 can 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 hose is widely used for application 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 the 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 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 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 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 the 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 the equipment, machine, vehicle which needs heat or power from the Petroleum-based fluids, water-based fluids,  gas, oil and etc.

Types of Hydraulic Hose

Here are many types of hydraulic hose, here I introduce some popular hydraulic hose types as follows.

In addition to the reinforced hose, the hydraulic 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.

SAE and EN Standards

Here are two set standards for the hydraulic hose, SAE standard, and 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 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 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 hose, and then it’s important to choose the right hydraulic hose, with the right specification, size, length, and 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 the inside. Also, consider 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.

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, or 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.
