Sleeve (hose) pressure pneumatic PN GOST 10362-76 32 mm are used as flexible pipelines for the supply under pressure of substances such as:
- air
- liquid
- carbon dioxide, nitrogen and other inert gases.
The high-pressure pneumatic hose is a flexible compact rubber hose used to supply compressed air flows from the compressor to the workplace and connect pneumatic tools (drill, wrench, jackhammer, pneumatic press).
The supply air is needed for drives in production, where it is the driving force. Many production mechanisms work with the use of air supplied through pneumatic hoses.
The list of fluids that are supplied through pneumatic hoses is quite extensive. This is primarily fuel: gasoline (automobile, aviation), fuel (diesel, etc.).
Also: petroleum oils, various lubricating fluids and cooling fluids.
The pneumatic sleeve is used for construction, road works, bridge construction, for connecting a pneumatic jackhammer to a compressor, at industrial, production facilities, factories, when connecting various pneumatic tools, as well as in domestic conditions.
Long length rubber pressure hoses with a filament frame are produced in accordance with the requirements of TU 38-105998-91; TU 38-1051731-86; 2554-108-05800952 and are a multilayer rubber product used as a flexible pipeline for transporting gaseous and liquid media under pressure.
According to TU 38-105998-91; TU 38-1051731-86; 2554-108-05800952 Rubber pressure hoses with a filament frame are produced with a bore diameter from 16 to 25 mm, depending on the design, they can withstand the pressure of the working medium up to 1.6 MPa (16 atmospheres). The length of the pressure hose can be agreed between the customer and the manufacturer individually and range from 20 to 50 meters.
The outer rubber layer protects the product from external factors: mechanical damage, ultraviolet radiation, etc. The inner rubber layer is in direct contact with the working environment, respectively, its chemical composition and mechanical properties depend on the purpose of the product, type of working environment, operating conditions.
Sleeves pressure head with a thread framework rubber made on TU 38-105998-91; TU 38-1051731-86; 2554-108-05800952 are divided into 3 classes:
B - technical water (without additives), solutions of inorganic acids and alkalis up to 20% concentration (except for nitric acid);
VG – hot water, working medium temperature up to +100°C;
G - air, carbon dioxide, nitrogen and other inert gases;
During operation, pressure hoses with a threaded rubber frame can be connected to the elements of a rigid pipeline by means of tight clamps or with the help of end fittings. By default, pressure hoses with a threaded rubber frame are supplied with “free” ends, but upon purchase, you can additionally order the termination of the end fittings (the type of fittings and the cost of work are determined individually).
A pressure hose is a lightweight and flexible rubber product designed to supply liquid and gaseous substances under pressure in pipelines. Products in this category are used at gas stations, in agriculture and utilities, in the field of fire fighting and even in the food industry. The strength and elasticity of the pressure hose is ensured by a multilayer textile frame. It consists of natural (linen, jute, hemp) or synthetic (rubber, latex, PVC, polyurethane) fibers. Also, the performance properties of the product depend on the impregnation, which is added to the composition of the material of the outer or inner shell. Thus, it is possible to change the useful qualities of products by obtaining pressure hoses of various types: wear-resistant; refractory; oil and petrol resistant (MBS); frost-resistant; waterproofing, etc. In accordance with GOST 18698-79, a separate product class is intended for each type of transported substances: B - for gasoline, kerosene, oil-containing oils. B - technical water and low-concentration solutions of alkalis and acids. VG - hot water supply. G - inert gases and air. Steam 1/2 - liquids in the gaseous state with temperatures up to +145 or +175 °C. P - drinking water, drinks, slightly acidic solutions of organic substances. Ш - abrasive materials. Also, similar rubber goods differ in diameter, length and working pressure. Features of fire hoses Flat-fold pressure hoses designed to extinguish fires deserve special mention. Soft hose made of synthetic fabric or tarpaulin can be stored as a roll. The compact shape allows the product to be placed inside a special compartment of a fire truck or a ShPK cabinet installed indoors. In an emergency, the rolled-up sleeve can be quickly restored to working condition. The presence of connecting fittings at the ends of the rubber productThis will not only allow you to quickly connect to a hydrant or foam generator, but also connect the hoses to each other. The requirements for the size of fire-fighting products are fixed in GOST R 53271-2009. The standard specifies the following characteristics: shrinkage of the material after drying - 5%; weight per person - no more than 25 kg; deformation in the transverse direction - up to 15%; power frame width - from 800 mm; the perimeter of the inlet (with a ratio of length to width up to 1.55) - not less than 1,600 mm. During operation, it is necessary to ensure a smooth supply of liquid, prevent mechanical damage due to the hose being dragged along the ground or falling from a height, and prevent chemicals from entering the outer layer of rubber goods (when extinguishing with foam). What is the difference between a pressure hose and a pressure-suction hose Fire and other types of pressure hoses are designed to work with substances under pressure in the system. The restriction does not apply to products of the pressure-suction category. This universal type of technical products is capable of not only moving the flow of a liquid or gas, but also taking a substance from a source under vacuum. In order to ensure operation under vacuum, the suction-delivery hoses are equipped with a metal spiral. Such a reinforced structure in the form of a corrugated tube is resistant to twisting or other mechanical stress. For example, when connected to a pump, the hose will not be damaged due to pressure drop. Rules of operation and checks In order for the RTI to fail prematurely, it is necessary to follow a number of recommendations for operation and maintenance. Do not allow hoses to be sharply kinked or come into contact with sharp or hot objects. Products must be stored dry and clean in a ventilated area. It is also required to regularly check the condition of flexible pipelines (at least once every six months). In order to optimize labor costs, it is allowed to test several hoses at the same time, lining them up in a line. To test the tightness, on the one hand, the RTI is connected to a hydraulic pump, and on the other, to a fitting with a tap. After removing air and filling with water, the system is pressurized for 3-5 minutes (depending on the material) to the calculated values and measurements are taken.
Areas of use
There are no technological restrictions that in any way affect the list of areas of application for pressure hoses VG for hot water. They can be used:
as pipelines, including temporary ones, at public utilities;
to create supply lines from pressure equipment in automated washing devices;
as constituent elements in hot water distribution units;
for the purposes of industrial production, transportation of water, which is part of technological processes.
However, the greatest number of options for the use of reinforced rubber hose VG is observed in everyday life and for the needs of various institutions. It can be used to connect gas boilers (hot water outlet) if it is not possible to connect a rigid pipe outlet to the device. Great convenience of switching is achieved in the case of building heating stations, which include hydraulic accumulators, heating equipment of direct and indirect action.
Naturally, we must not forget about the simplest version of the use of a rubber reinforced hose VG. It connects hot water endpoints such as faucets, shower columns and more. At the same time, there are no sanitary, hygienic, technological or other restrictions on the use of the product.
