A rubber hose is a flexible pipeline designed for transportation of liquid, gaseous, free-flowing working medium. Depending on the version, the technical product is operated under a certain pressure and temperature conditions. All rubber sleeves GOST or TU, and buy they are offered by USA LLC.
Overview of sleeves, main characteristics
Each type of industrial rubber product is different in the device, materials of manufacture. To choose the right one for certain jobs, you need to familiarize yourself with the characteristics.
Unreinforced pressure head with thread braiding
Technical products are intended for supplying a liquid working medium, air, and inert gases under pressure. Rubber pressure hoses conform to GOST 10362-76. The construction is a double layer of rubber with an intermediate lining of a thread carcass, planted on an adhesive paste. Efficiency remains in the temperature range from -60 to +90 o C.
Use rubber water hose utilities. In the oil refining and chemical industries, they pump lubricants, fuels, all acids with a concentration of up to 20%, except for nitric.
Pressure head with thread cage
Products comply with TU 38-105998-91, consist of 2 layers of rubber with an intermediate thread frame. Efficiency remains in the temperature range from -35 to +50 o C. Marking with the letter “P” means that sleeves for foodstuffs are intended: milk, alcoholic drinks, other liquids. They are in demand in the food industry.
Marking with letters "B", "G", "W" indicates the possibility of using for pumping oil products, gas, abrasive bulk materials. The abbreviation "B", "VG" means that water hoses for technical purposes. The product "VG" can withstand operating temperatures up to +100 o C. For every rubber pressure hoses price differs depending on the purpose and diameter. Scope: construction, oil refineries, other enterprises.
Pressure head with textile frame
The product complies with GOST 18698-79, consists of two rubber layers, one or more textile frames between them. rubber hoses for steam with a temperature from +143 to +175 o C. Other types are intended for oil products, hot water, abrasive bulk materials, gas, food liquids. Operating temperature range from -35 to +100 o C. Each product has its own label.
Pressure and suction with textile frame and metal spiral
The product complies with GOST 5398-76, consists of rubber layers reinforced with a metal spiral and a fabric frame. The end is equipped with a soft cuff for connecting to the reinforcement. The form is smooth or corrugated. Operating temperature range from -35 to +90 o C.
Hoses are used in production where it is required to pump food liquids, industrial water, acids, alkalis with a concentration of up to 20%, oil products, gas.
Unreinforced high pressure with metal braids
The technical item complies with GOST 6286-73, consists of two layers of rubber, between which one or two wire braids are enclosed. The temperature range of the working medium is from -50 to +100 o C. The hose is intended for enterprises where pumping of oily liquids, oil products, water is required.
Unreinforced with metal windings
The technical product is intended for pumping liquid, complies with GOST 25452-90, DIN 20023, as well as TU 38605111-90. The sleeve has 2 layers of rubber, between which there is a textile braid and 4 coils of metal wire. Working medium temperature range from –40 to +93 o С. It is used in enterprises where pumping of water, oil products, water-oil liquids is required.
For gas welding
The product complies with GOST 9356-75, has 2 rubber layers with an intermediate thread braid. Hoses for gas welding are , designed to provide the supply of acetylene, gas, gasoline, other liquid fuel or oxygen to the equipment. Efficiency is maintained at temperatures from -55 to +70 o C. hoses for gas and welding are in demand by enterprises, individuals engaged in cutting metal, manufacturing metal structures.
Pressure antistatic for fuel dispensers
The sleeve is intended for supplying oil products. Efficiency is maintained at temperatures from -40 to +55 o C. The product complies with TU 38105888-80, consists of 2
