从全球市场供应商批量进口Pressure Hose With Textile Frame Gost 18698 79 A3ab

PRESSURE HOSE WITH TEXTILE FRAME GOST 18698-79 GOST 18698-79 Rubber hose with an integrated load-bearing frame made of textile fibers are used to transport liquids or gases with high pressure and temperature. There are several types of products that different in the resistance of the material to the effects of pumped substances. GOST 18698-79 GOST 18698-79 Rubber hose with an integrated load-bearing frame made of textile fibers are used to transport liquids or gases with high pressure and temperature. There are several types of products that different in the resistance of the material to the effects of pumped substances. The industry produces hoses with different inner diameters, which determine the performance of transporting a gas or liquid medium. Main varieties In accordance with GOST 18698-79, reinforced pressure hoses are divided into groups: �? â?? intended for the transportation of petroleum products and motor fuel (gasoline, diesel fuel and kerosene). Permissible temperature of mineral-based oils being pumped is -35...+100, and other liquids -35...+70. Used for transporting technical water without mechanical impurities, aqueous solutions of acids and alkalis (the share of the active substance is not more than 20%). It is possible to work when the flow is heated up to +50. Products are not used for pumping nitric acid, which destroys rubber walls. Intended for transportation of water heated up to +100. PAR 1 and PAR 2 - designed for pumping saturated water vapor at a temperature of +143C and +175C, respectively. Used to supply air with abrasive mechanical particles, for example, in power systems for sandblasting equipment. Pumping of weak aqueous mixtures of alkalis or acids is allowed. The operating temperature is in the range -35...+50. Additional differences In accordance with the GOST 18698-79 standard, the products have 3 versions for different external conditions. The industry offers products for temperate, tropical and cold climates. When selecting products, the temperature of the ambient air (for outdoor installation) and the transported medium are taken into account. The standard provides for the release of hoses that can withstand gas or liquid pressure of 6.3, 10, 16 and 20 atm. The company has a stock of hoses of the main standard sizes. In the absence of the required quantity of products, the delivery time is from 5 to 10 working days, necessary for the production of the required batch of rubber-reinforced hoses. In the absence of the desired item in the catalog, you should submit a request by e-mail or phone to calculate the delivery time and price of rubber products.
