Spiral hydraulic hose are used in many industries, application and machiney such as mining, oil exploration, carry all kinds of hydraulic fluids oil and other consists of four or six high-tensile wire that exhibits exemplary strength, making the hose very strong but also very rigid. The resistance to pressure spikes is exceptionally high, especially compared to a braided hose.

How Does Spiral Hydraulic Hose Work?

As we know, hydraulic hoses are constructed in layers. The inner tube carries the fluid, and this is usually the one that is the most flexible of the three. Outside the inner tube is a reinforcement layer, which generally has some sort of protective mesh or design to prevent breakage. Finally, there is a protective outer layer, which is usually designed to be weatherproof and heat-resistant. How does the spiral hydraulic hose work? Actually, the basic working principle is the same as hydraulic hose, main is conveyed hydraulic fluid. But the difference is the spiral hydraulic hose consists of two, three, four, or more layers of high tensile steel wire spiral that can add much more strength, to make the hydraulic hose become very strong, with high resistance to high pressure compared with the braided hydraulic hose. The application of the hydraulic hose is what determines how it works. For example, the reinforcement wires in a spiral constructed hydraulic hose remain parallel as they perpendicularly wrap around the hose in layers. You will find spiral wire hoses in heavy duty construction equipment and are designed for their strength and high-impulse applications.

How to Prevent the Spiral Hydraulic Hose Burst?

We know that hydraulic hose burst is a common and important problem in hydraulic work. If it is not dealt with in time, it will lead to bigger problems. So how to prevent the burst of spiral hydraulic hose?

The quality of the hose itself is very important. The most important thing is to choose a quality hose. If hose quality is not qualified, the service life of the hose will be greatly shortened, and it is extremely prone to bursting problems. Then you need to refer to the hose data sheet to select the correct hose to apply to the equipment. If the selected hose does not match, or the assembly is not correct, there will also be a burst problem;

In addition to the quality problems of the hydraulic hose itself, there may also be problems with the hydraulic system itself. For some reasons, such as the preset pressure is too high, the pressure on the hose will be too high, which increases the chance of bursting of the hose. So the hose needs to meet the standard burst factor, and reduce preset pressure to avoid damage and loss of hydraulic hoses. If the working environment of the hose is harsh, such as the hose being exposed to high temperature for a long time or continuous friction, you can also choose a suitable protective cover on the outside of the hose to prevent the hose from bursting.

What is the Pressure Range Difference Between Different Types of Spiral Hydraulic Hose?

The different spiral hose type has different working pressure range. There are two types, variety pressure and constant pressure. Below are detailed pressure ranges.

Variety pressure: 4SP/4SH, rated for maximum working pressures from 16.5 to 45 MPa (2,393 to 6,527 psi);

Constant pressure:

R12 type spiral hydraulic hose, constant max working pressure is 28 Mpa(psi);

R13 type spiral hydraulic hose, constant max working pressure is 35 Mpa(psi);

R15 type spiral hydraulic hose, constant max working pressure is 42 Mpa(psi);

In addition to the above common spiral hydraulic hose type, UGW factory has "WA" and "UA" series constant pressure four-layer spiral hose, which has ultra-high wear resistance and can reach millions of pulses, etc. Contact us if you want to know more detailed product data.

What Pressure Range Can the Spiral Hydraulic Hose Withstand?

For spiral hydraulic hose working pressure range, different type has different working pressure. The usually spiral hydraulic hoses are 4SP/4SH, and available in sizes from ¼ to 3 in, which is rated for maximum working pressures from 16.5 to 45 MPa (2,393 to 6,527 psi);

Then there are 4 layers and 6 layers of constant pressure spiral hose.

R12 type spiral hydraulic hose, size from 3/8 to 1(four layers), constant max working pressure is 28 Mpa(psi);

R13 type spiral hydraulic hose, size from 3/4 to 1(four layers) and 1 1/4 to 2(6 layers), constant max working pressure is 35 Mpa(psi);

R15 type spiral hydraulic hose, size from 1/2 to 1(four layers) and 1 1/4 to 2(6 layers), constant max working pressure is 42 Mpa(psi);

In addition to the above conventional spiral hydraulic hose, UGW factory also has ultra-high constant pressure four-layer spiral hose, which have ultra-high wear resistance and can reach millions of pulses, etc. Contact us if you want to know more detailed product data.

Is the Spiral Hose Better Than the Braid Hose?

First of all, you have to understand the structure of spiral and braid and their respective characteristics before you judge which one is better.

The spiral hose is 4 or 6 layers of steel wire reinforcement, while the braid is one or two layers of steel wire reinforcement. The spiral hydraulic hose is reinforced with the spiral steel wire, the spiral constructed steel reinforcement can remain parallel, wrapping the hydraulic hose firmly, making it solid and not easy to be bent over. It can withstand greater working pressure, but it is relatively rigid, has poor flexibility, and is not easy to operate flexibly;

Compared with one or two layers of steel wire braided reinforcement, due to the braid hose structure, the braided hydraulic hose can provide more flexibility due to its low bend radius with the help of criss-cross braided steel wire physical performance. The braided reinforcement of the hydraulic hose can make it much more flexible for you to locate it for a better hydraulic hose routing and suitable for low to mid-working pressure.

Now you must know how to answer is the spiral hose better than the braided hose? The answer is not sure, each type of hose is different and suitable for different applications, you should choose the appropriate hydraulic tube according to your own application, no one is better, only the right one is the best.

How to Install Spiral Hydraulic Hose?

First of all, it is necessary to select the spiral hydraulic hose of the appropriate length and to ensure that the hydraulic hose after installation maintains a certain degree of slack, neither too tight nor too loose, to avoid tensile stress or wear.

The second is to avoid twisting the assembly and confirm that the assembly is smooth and correct. When installing the spiral hydraulic hose, if it is necessary to bend the hose, the bend radius of the hose cannot be smaller than the minimum bend radius of the hose to avoid a narrow bend radius.

what's more, it is also necessary to avoid contact with objects to prevent unnecessary friction and affect the use of the hose.

What Standards Does the Spiral Hydraulic Hose Implement?

In the hydraulic market, there are different hydraulic hose standards. In the Chinese market, there are Chinese hydraulic hose standards, like GB-, GB/T -, etc. In the international market, there are several different national and international hydraulic hose standards, of which three are common and have been widely recognized, one is the European standard (EN) and the international standard (ISO) and the American standard (SAE). The spiral hydraulic hose also implemented the above standards in the international market. For example, the standards for four-layer spiral hose description are, ISO -1, EN 856, SAE 100 R12...

What Are the Criteria for Selecting the Spiral Hydraulic Hose Supplier?

No matter what role you play in the hydraulics market, it's necessary to stock some good hose suppliers. When you meet the problem with your current supplier, or need to repair/replace a hydraulic hose, a good hose supplier is very important. So how to choose a hydraulic hose supplier? Here are some tips for your reference.

Suppliers Scale

First of all, you need to know hose suppliers' scale. If it is a manufacturer, you need to know the factory area, the number of people, production lines, machinery and equipment, etc.; If it is a trader, you need to know whether there is a stable hose supply.

Quality of hose

The quality of the product itself is the top priority. You should learn the raw materials, the production process, QC, and technical data.

Hose price

Don&#;t buy based on price alone. The prices of hydraulic hoses can vary dramatically - and it&#;s not always wise to choose the cheapest option available. When selecting a hydraulic hose, make sure that price isn&#;t the only factor you consider

Other factors, like delivery time, service...
