Rating of the best high pressure hoses for 2020

The hose is a reinforced hose, which is equipped with all kinds of transition connections, thanks to which it can be mounted to various units, hydraulic systems and mechanisms. In most cases, it is installed on bends and in the presence of movable elements, for example, to raise an excavator bucket.

What are and how they differ

Such devices, regardless of the popularity of the models, are similar in their design features, despite the variety of manufacturers. They are a structure consisting of several layers:

Layer viewDescription
Inner sealing rubberIn the manufacture, rubber is used, which has a special composition, thanks to which the hose becomes airtight, perfectly copes with aggressive media, does not stretch or deform.
Metal reinforcingThe main materials of manufacture are wire and high-strength synthetic threads. The number of layers may vary depending on the use of the fixture.
Outer protective rubberThe main task is to protect the product from external negative influences, to ensure the strength, durability and reliability of the hose.

Despite the varieties, the products are equipped with metal fittings, thanks to which they are connected to all kinds of systems.

RVD are of the following types:

  • with winding;
  • with braid.

The most popular in Russia is braided models due to the fact that coiled turns are prone to divergence during bending, therefore, they have a larger bending radius than braided ones.

It is worth noting that winding structures withstand increased performance, since during their manufacture the maximum number of layers reaches six pieces, while the braid involves only three layers.

Product manufacturing rules

For the manufacture of RVD, innovative production technologies are used. The process itself involves the passage of the following technological stages:

  1. The length of the product is determined. A specific calculation is needed in order to distribute a uniform load throughout the device. The cutting is carried out using a special cutting machine, which makes it possible to make the pipeline clean and durable.
  2. Processing the fixture with a debarker. It is not always necessary to remove the rubber outer layer. Hoses type 2 SN are stripped.
  3. Pressure testing and assembly. The hose on each side is equipped with couplings and fittings up to the stop. It is necessary to pay attention to the fitting locks, which must match exactly with the coupling. After that, the finished product is pressed.
  4. The final step is labeling and packaging the product. It must be remembered that RVD has a certain shelf life, so you need to seriously approach the packaging technology and follow the storage rules. The packaging displays the technical characteristics of GOST, which were used in the manufacture of a specific batch of products.

Technical features of flexible pipelines

Products differ in parameters that affect their categorization. The main selection criteria are:

  • Operating temperature range;
  • bend radius;
  • working pressure indicator.

The temperature index at which the product is able to function efficiently is defined by International Standards and ranges from -40 to +100 degrees Celsius.

The value of the bend radius plays a significant role, since the usability of the product depends on it. The larger it is, the less functional the pipeline will become. The requirements for the bend radius are specified in GOSTs and depend on the product category.

Absolutely all popular models of hoses from the best manufacturers, whether coiled or braided, have their own operating pressure limit. They are reflected in European standards and in GOSTs applied on the territory of the Russian Federation. Many manufacturers have established the production of hoses for work in extreme conditions, where the temperature reaches -50 or -55 degrees Celsius.

Scope of use of RVD

The products are used in almost all high performance hydraulic systems. Practice shows that using this type of product is more efficient and justified than working with rigid metal tubes.

RVD is actively equipped with modern complex equipment, which includes both pneumatic and oil drives. This is about:

  1. Gas supply and water supply systems.
  2. Excavators, asphalt pavers, tractors of various brands and other similar mechanisms.
  3. Road construction, communal and other specialized equipment.
  4. Devices with the function of transporting various working fluids and liquid fuels.
  5. All kinds of equipment that is used in mechanical engineering, metallurgy, oil production and refining industries.
  6. Drilling rigs.
  7. Lifting equipment.
  8. Machine tool equipment.
  9. In enterprises related to logging, food processing, mining, woodworking and so on.
  10. Agricultural machinery and units.
  11. Trucks and cars.

Modern structures of this type guarantee complete tightness during the transportation of all kinds of liquids. There is no need for auxiliary seals. The functional hose is selected taking into account the scope of its use and types of systems.

The peculiarities of flexible pipelines are that they have such unique properties that they can function efficiently under any increased loads and in the most aggressive environment.

How to choose the right option

It is worth noting that such devices are developed and produced taking into account the increased strength, reliability and long service life. Mistakes in the choice can cause a breakdown of the system, its exit from standing, which will lead to significant financial costs, and possibly injury to employees of the enterprise.

The basic and sufficient characteristics of a product are determined at the stage of designing a specific system. Any hose has an individual purpose and its inappropriate use will lead to damage to the entire product.

The main point is to accurately determine the length of the unit. It should be borne in mind that, depending on pressure surges, this indicator may change. When using the product in hydraulic installations, the sleeve will constantly bend and unbend, as well as carry out certain movements. The result of such actions is the constant friction of the parts against each other. With rare contacts, this equipment will withstand such loads. In case of frequent friction, it is necessary to replace the sleeve with a shorter one.

The recommendations of the experts boil down to the following: determine for yourself which company's product is better, and try not to change the manufacturer. According to buyers, this applies not only to hoses, but also to other components.

What else should you pay special attention to? The indicator of the maximum allowable pressure in the system. It is necessary to pay attention not only to the value of constant loads, but also to variables that occur due to the turbulence of the system, including jumps in the impulsive plan. It is best to take products with a certain stock.

Which one is better to buy depends on many factors, including the scope of use, as well as on the indicator of the aggressiveness of the environment. The best products are ranked as high quality and reliable. There are several options for where to buy the necessary equipment. It is best to visit a specialized outlet, get acquainted with new products, understand for yourself what it costs, and get advice from a sales manager. If you decide to order products online in an online store, then you should carefully review the proposed photos, read the reviews.

Home use and repair

The main field of application of hoses is in hydraulic and pneumatic structures. They are also widely used in the automotive industry. All drivers know how, thanks to the built-in power steering, the steering wheel can be turned without significant effort. But with significant operation, deformation of the sleeve and tube may appear, which will lead to instability of the unit itself. It is possible to correct the situation on your own or by contacting a service station to specialists.

Motorists are constantly faced with problems in the operation of hydraulics, which inevitably leads to product replacement. The main reasons for the occurrence of an emergency situation are:

  1. Working out the operational life. Mechanical damage occurs due to natural wear and tear of the equipment. Major problems include frayed areas, cuts and cord breaks. They appear, as a rule, due to the incorrectly chosen sleeve length.
  2. Defect in the manufacturing process. As a rule, this concerns the purchase of an inexpensive device from a little-known manufacturer. Possible crimping of the fitting or hose joint. Improperly configured or out-of-order hardware can also be the cause.
  3. Incorrectly selected specifications or temperature indicator. If the main indicators of the product do not coincide with the real environment of its use, then this will negatively affect the quality of functioning and durability of use.
  4. Inconsistencies in the constructive plan. Trouble arises if the installed equipment does not correspond to the parameters specified by the manufacturer. This is fraught with wire breakage, breakage of fittings, if the provided indicator is lower than the actual one (in the system).

You should pay attention to this

It is strictly forbidden to operate the car if the following malfunctions occur:

  • the sleeve is completely or partially clogged;
  • there was a significant break in the hose;
  • corrosion has appeared on the fittings;
  • the outer part of the sleeve is too worn out;
  • joints allow liquid to pass through;
  • the fitting fell off the bore diameter;
  • connections are depressurized;
  • overestimated temperatures and significant pressure led to damage to the inner surface of the sleeve.

If the above breakdowns occur, it is worth replacing the sleeve. If you have never done this with your own hands, step-by-step instructions posted on the Internet will come to the rescue. It clearly and clearly describes the actions, how to remove, how to replace the device, how to put it back, what accessories will be needed for this.

It is possible not to carry out a complete replacement of the product, but to try to repair it. It all depends on the maintainability of this or that product. A damaged area with scuffs, cuts and cracks can be replaced with a new one. As for the repair of high-pressure hoses on Karcher, experts believe that this is an almost hopeless business. If damage occurs in a straight section, the material is crushed or chopped up, then it is quite difficult to acquire a two-sided type Christmas tree branch pipe and squeeze it with your own hands.
