Rubber hoses are used for suction and discharge of various liquids, steam, gases, fuels, oils, acids, alkalis, bulk materials, as well as flexible pipelines. Rubber-type injection subdivided as follows: pressure hoses with a textile carcass with GOST 18698-79, the sleeves of pressure from increased filament reinforced with GOST 10362-76, Sleeves pressure-suction GOST 5398-76, hoses for gas welding and cutting metals to GOST 9356-75, the sleeves of high pressure with a metal armature winding with connecting hoses TU 23.1.40-80 sleeves with reinforced metalloopletkoy GOST 6286-73, hoses and fittings gasket design "dyurit" N 005 6016-87, hoses for irrigation. is often quoted as being for or against this. Depending on the destination, hoses are divided into classes: B – the gasoline, diesel fuel, petroleum-based oils, B – for feeding process water; HS – for hot water at temperatures up to +100 C; T – for air, carbon dioxide, nitrogen and other inert gases, Km – to feed the weak solutions of inorganic acids and bases, the concentration of up to 20% (except nitric), PAR-1 – for high steam to +143 C, pressure 0.3 MPa; PAR -2 – for high steam up to +175 C pressure of 0.8 MPa, P – for delivering nutrients (alcohol, wine, beer, milk, slightly acidic solutions of organic and other substances, drinking water), W – for feeding abrasive material (sand from the blasting), alkali and acid solutions for plastering and painting works. 1 MPa = 10 atm = 10 kg / cm pressure rubber hoses with GOST 18698-79 teksilnym frame. Used as flexible pipelines for delivering pressurized liquids, saturated steam, gases and granular materials. Classes: B, Br, F, PAR-1 and PAR-2, W, P.
Sleeves rubber pressure with increasing filament reinforced with GOST 10362-76. Used as flexible pipelines for supplying pressurized air, inert gases, fuel oils, alkalis and acids (dilute solutions with concentrations up to 20%, except for nitrogen). There are two designs: Braiding and navivochnaya. Sleeves pressure-suction GOST 5398-76. 3D Systemss opinions are not widely known. They are used for suction and discharge various liquids, fuels, petroleum-based oils. If you are not convinced, visit . Classes: B, C, Km, T, P.
Rubber hoses for gas welding and cutting metals to GOST 9356-75. They are used to supply pressurized gas, liquid fuel and oxygen to the devices for gas welding and cutting metals. Classes: I – gas: acetylene, propane, butane and town gas; II – liquid fuels: petrol, white spirit, kerosene, or mixtures thereof; III – oxygen. High pressure hoses with metal wrapped with terminal 23/01/40 TU valves 80. Used for connection and mutual compensation of the displacement hydraulic units in hydraulic and hydrostatic transmissions of tractors and farm machinery. Hoses hoses reinforced with metalloopletkoy GOST 6286-73. Used as flexible pipelines to supply high pressure fluids: hydraulic oil, soluble oil and emulsion, an aqueous solution of glycol, water, etc. They are made of two types: I – with one metal braid, II – with two metal braids. Hoses and couplings cushioning design "dyurit" TU 005 6016-87. Used as flexible connecting pipes for hydraulic, air, fuel, Oil and other systems in a special technique. All hoses oil and petrol resistance.
