For transportation of liquids (oil, water, fuel, glycol, emulsion, grease, other technical liquids) and gases use high pressure hoses with maximum values of several hundred atmospheres. The design of the RVD is resistant to a pressure of several hundred atmospheres. Practical use of RVD - hydraulic, pneumatic systems of various mechanisms and machines. In the process of operation, it becomes necessary to HVD repair .
RVD repair removes defects:
- kink, leak, rupture, blockage of the sleeve;
- wear of the outer layer of the sleeve;
- corrosion, leakage of fittings.
The structure of the RVD will include three rubberized layers - outer, intermediate and inner. A metal braid or winding located between them gives rigidity to the product. Small diameter steel wire, polymer or textile thread are used for winding. According to the method of wire winding, two types of high pressure hoses are distinguished: coiled and braided.
The material of the inner layer of the sleeve is resistant to the influence of transported liquids and gases. At the ends of the sleeve, metal connections are installed - fittings. Fitting types - quick couplings, nuts, unions, nipples. The fittings are attached to the ends of the hose with crimp couplings using specialized equipment. There are two methods of pressing fittings: transverse and longitudinal.
RVD marking is applied by embossing on the sleeve surface. Indicate the product name, inner diameter, maximum working pressure, length, type of climatic version, date of manufacture.
