Selecting the right industrial hoses for your fluid systems requires careful consideration of a variety of factors, including media pressure, temperature of media and the surrounding environment, flow rates, and more. The hose&#;s ability to meet your specific system requirements largely depends on you choosing an optimized combination of hose components properly rated to withstand application conditions.
One key industrial hose component to think about is the hose reinforcement layer. On its own, a hose&#;s core can only handle very low pressures. A reinforcement layer is incorporated to give the core tube strength both axially and longitudinally, helping the hose withstand the demands of the application.

While there are many factors that contribute to hose longevity, choosing a hose with a strong reinforcement layer is an important one&#;and not all available reinforcements are the same. Here are a few important reinforcement layer characteristics to consider when working with your hose supplier in order to make the best selection for your application:
Hose reinforcement layers are made up of wires of a certain material (commonly fiber, stainless steel, or some form of plastic). Two styles are most commonly seen throughout the industry: coiled and braided.
Coiled reinforcements are typically easier to manufacture but can often lack the strength of their braided counterparts. When hose is pressurized, a coiled reinforcement tends to untwist itself, tearing at both the hose core and its cover. As this happens, failure is inevitable. While coiled reinforcement may be cost-effective in the short term, it often does not offer good longevity, especially at higher pressures. Swagelok does not produce hoses with coiled reinforcement for this reason.
Braided reinforcements, by contrast, combine the reinforcement wires in a much stronger and resilient configuration. Unlike coiled reinforcement, braided options will not untwist when the hose is pressurized. This configuration helps the hose more reliably withstand pressurization and provide greater longevity.
Inquiring about reinforcement style with your hose supplier and seeking stronger, braided reinforcements can help save time, labor, and money on frequent hose replacement. Hoses are subject to operational wear in any fluid system, needing regular maintenance and occasional replacement. They can be thought of similarly to tires on a vehicle&#;while no one buys a car and expects tires to last forever, choosing a higher-quality product can lead to greater longevity. In a fluid system, a high-quality hose can contribute to significant maintenance and operational benefits.

Next, the right type of reinforcement material should be considered. As noted earlier, hose reinforcements are available in fiber, stainless steel, plastic, or other materials. Each has its own influence on the end-use performance characteristics of the hose.
Application needs will often guide the choice of reinforcement material, along with the materials that make up the hose core, cover, and end connections. For example, a stainless-steel braided reinforcement layer paired with a complementary core material will offer outstanding pressure and temperature resistance. A stainless-steel braided hose may not, however, deliver proper flexibility or dynamic performance in applications where pressurization is inconsistent (such as hydraulic equipment operation).
Another important consideration for choosing the right hose reinforcement material is conductivity, which is desirable in certain applications but may pose a significant safety or performance risk in others. A hose with a braided metallic reinforcement layer will be conductive, allowing large electron current flow from one end of the hose to another. In the case where the two ends need to be electrically isolated, the hose needs to be nonconductive. A nonmetallic reinforcement layer and complementary core would be a better choice here.
Different braid materials will also command different price points. If an application allows for the use of either a fiber braid or a stainless-steel braid, stainless may often come at a higher price point&#;but may also contribute to longer-lasting performance by contributing greater overall hoop strength and resistance to kinking. Working collaboratively with a hose supplier who can help you determine the best value for your application is beneficial, helping you cost-effectively achieve consistent, reliable performance.
Braids can come in various wire thickness and pitch angles, which will impact flexibility, strength (pressure rating), temperature performance, and many other factors. Braids should also be complementary to the core material to provide the best performance and value.
For example, a corrugated metallic core will grant the hose significant hoop strength on its own. A complementary braid reinforcement design should be flatter, providing greater resistance to the core growing in length (rather than diametrically). Here, the angle at which the braid wires intersect with each other can deliver different performance characteristics depending on the needs of the application.
Elsewhere, the attributes of the braid wiring itself can influence hose performance. Some reinforcement braids are composed of fewer, thicker wires. These types of braids are easier to manufacture; however, the resulting hose is typically limited in its flexibility. A reinforcement braid that consists of many thin wires can deliver more desirable levels of flexibility without compromising strength and pressure resistance.
Not all hoses for critical industrial fluid system applications are manufactured to the same high standard&#;varying quality in reinforcement braiding is just one of the reasons why. With a working knowledge of reinforcement braids and how they impact overall hose performance, operators can be better prepared to achieve the highest possible performance and reliability in their systems. Maintaining a relationship with hose suppliers willing to collaborate on hose designs is helpful, as well.

For companies that want to invest in high-pressure hoses to develop business, it is very important to choose an excellent high-pressure hose supplier. However, there are so many excellent high-pressure hose suppliers in China, how should we choose? Today we will tell you.
What is high pressure hose
Hydraulic hose is also known as hydraulic oil hose, hydraulic hose, high pressure hose, hydraulic hose, steel wire high pressure hose, steel wire braided hose, steel wire winding hose, generally divided into steel wire braided hydraulic hose and steel wire winding hydraulic hose.
Hydraulic hoses are divided into two categories according to material: rubber and rubber-plastic material. According to the production process, it is divided into steel wire braided hoses, steel wire wound hoses, wire braided hoses and sandwich hoses.
High pressure hose structure
It is mainly composed of inner rubber layer, middle rubber layer, multi-layer reinforced layer and outer rubber layer of synthetic rubber which is resistant to liquid.
The inner rubber layer has the function of making the conveyed medium bear pressure and protecting the steel wire or wire fiber from erosion, the outer rubber layer protects the reinforcement layer from damage, the reinforcement layer is the skeleton material, the function is to ensure the use pressure of the hose.
High pressure hose use
mainly used for mining hydraulic support, oilfield development, suitable for engineering construction, lifting transport, metallurgy forging, mining equipment, ships, injection molding machinery, agricultural machinery, a variety of machine tools and various industrial sectors mechanized, automated hydraulic system with a certain pressure and temperature of petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsion, water) and other liquid transmission. Hydraulic hoses made of rubber and plastic materials, also known as rubber and plastic hoses, are a new type of hoses with obvious corrosion resistance and energy saving effect.

How to choose high pressure hose
Hydraulic hoses are an important part of hydraulic machines, which use liquid fluid power to perform simple and heavy work. It can be roughly divided into low pressure, medium pressure and high pressure. These hoses are designed to transmit hydraulic fluid to hydraulic motors and hydraulic cylinders to perform various functions.
The selection of hydraulic hoses should comply with rules such as temperature, pressure and the surrounding environment, all of which can have an impact on hose degradation. There are several main criteria to keep in mind when selecting.
Size
The dimensions, especially the inner diameter, should be appropriate to keep pressure losses to a minimum and to prevent extreme heat and excessive turbulence.

Pressure
Pressure is the maximum working pressure during continuous operation. According to the relevant international standards, Laike hydraulic hoses have a safety factor of 4:1, i.e. the maximum working pressure is approximately one quarter of the minimum burst pressure.
Impulse pressure
An important factor in hose selection is the pressure, which is calculated from the minimum burst pressure. In general, the maximum working pressure is one quarter of the minimum burst pressure with a safety factor of 4:1. The impulse pressure generated during operation is much higher than the working pressure. Hydraulic presses that are frequently attacked by impulse pressures are usually equipped with relief valves.
Temperature
Hydraulic hoses should be used within the specified temperature range. If the operating temperature exceeds this range, the service life of the hose will be significantly shortened and its operating pressure will be much lower. For too high or too low temperature working environment, the hydraulic hose should be protected by a hose jacket.
Chemical compatibility
When using special hydraulic fluids, hydraulic hose assemblies including hoses (tubes and covers, O-rings and fittings) should be fluid compatible.
Bend radius
When installing components, due attention should be paid to the minimum bend radius. A radius that is too small will shorten the life of the hose and increase costs.
