PRESSURE RUBBER HOSES (HOSES) FOR COLD AND HOT WATER WITH TEXTILE FRAME
GOST 18698 - 79
DESCRIPTION AND TECHNICAL CHARACTERISTICS Rubber pressure hoses for water with a textile frame
GOST 18698 - 79
are used as flexible pipelines for supplying pressurized liquids, saturated steam, gases and bulk materials in areas of cold, temperate and tropical climates. Reinforced pressure hose (also often called a sleeve) must not be used for gas cutting and welding of metals, as well as used as hoses for cars, agricultural machinery and instead of pressure hoses for special purposes. The sleeve (hose)
GOST 18698 - 79
is based on a frame (textile), rubber layers inside and out, as well as one or more (depending on the diameter of the manufactured sleeves) layer of fabric lining. Hoses are classified as pressure hoses. Reinforced water hose is produced in batches. Each batch undergoes acceptance tests for compliance with the requirements of the Technical Specifications. Test samples are taken from each batch, which are checked for tightness by pneumatic and hydraulic pressure Water supply hoses are divided into the following types: TYPE B II - Purpose : Technical water (without additives), solutions of inorganic acids and alkalis of concentrations up to 20% (except for nitric acid solutions) Working temperature: up to + 70C. Pressure: 6.3m; 10atm TYPE VH III - Purpose : Hot water Working temperature: up to + 90C. Pressure: 6.3m; 10 atm. The textile frame located inside such a sleeve can contain one or more layers, which are a special type of high - strength non - dyed fabric. Pressure hoses for hot water with fabric reinforcement are hermetically sealed, have a fivefold breaking safety factor Example of a symbol : Sleeve VG 38 - 10atm

Hose for irrigation (garden hose) 1 inch (diameter 25mm) 1/2 inch (diameter 12 - 14mm) 3/4 inch (diameter 18 - 20mm) FIELD OF APPLICATION OF PRESSURE HOSE FOR WATER Rubber pressure hoses with a textile frame GOST 18698 - 79 are used in industry everywhere, since they are an ideal option for arranging flexible pipelines that can withstand significant pressure. The hoses can be used for pumping liquid and gas media, bulk materials under pressure. The features of such a pressure hose include a multilayer structure: in the wall of the hose there are several layers of fabric (frame), which gives the structure its rigidity and strength. Water pressure hoses are widely used for irrigation, the so - called watering hoses. You can also purchase
