1. Product structure type: It is mainly composed of liquid-resistant inner rubber layer, middle rubber layer, 2 or 4 or 6 layers of steel wire winding reinforcement layer and outer rubber layer. The inner rubber layer can withstand the pressure of the conveying medium and protect the steel wire from erosion. The cover protects the wire from damage. The steel wire (medium 0.3-2.0 reinforced steel wire) layer is the reinforcement of the skeleton material. 2. Product use: High-pressure steel wire reinforced hydraulic hoses are mainly used for mine hydraulic supports and oilfield exploitation. It is suitable for mechanization of engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and industrial sectors. Petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil), water-based liquid (such as emulsion, oil-water emulsion, water), etc. Note: The standard of wire wound hose refers to GB/T10544-03 standard, DIN20023 standard, SAE100R9~13 standard, this standard is not applicable to castor oil-based and grease-based liquids. 3. Product Features: 1. The rubber hose is made of special synthetic rubber, which has excellent oil resistance, heat resistance and aging resistance. 2. The hose has high bearing pressure and excellent pulse performance. 3. The tube body is tightly combined, soft to use, and less deformed under pressure. 4. The rubber hose has excellent bending resistance and fatigue resistance. 5. The fixed length of the steel wire wound hose is 20 meters, and it can be made within 50 meters according to the requirements. 4. Applicable temperature: -30~+120℃. 5. All high-pressure hose assemblies produced by Changan are made of high-quality steel wire braided hose or steel wire wound hose and hose joints, which are crimped by special equipment. According to user needs, high-quality carbon steel joints, stainless steel joints, copper joints, aluminum joints, etc. can be selected. The joint form and thread strictly refer to the national standard metric system (JB1891-1900-77), American standard, British standard, etc. The data is accurate, the structure is reasonable, the assembly is convenient, and the buckle is tight. Under the working conditions of high temperature, high pressure and pulse, there is no leakage, no head loss, high safety factor and long service life. Special-shaped joints and joints can be designed and produced according to user needs. Precautions: 1. The bending radius should not be less than the given bending radius to prevent the hose skeleton from being damaged or damaged early due to overstretching. 2. According to the conditions of use, choose the type and specification of the hose correctly, and do not use it wrongly or substitute it. 3. When using the hose, the pressure should be adjusted slowly and balanced to avoid sudden increase in pressure and damage to the tube body. 4. When the working place changes, it should be carried off the ground, and the ground should not be mopped, so as to avoid corrosion of the skeleton layer after scratching the outer rubber. 5. When conveying corrosive liquids, the interior should be removed after use to prevent the residue from corroding the pipe body for a long time, or select the corresponding series of products. The above steel wire winding hoses refer to the GB/T10544-03 standard, please inquire if the specifications are not exhausted! Refer to the technical standards for high-pressure oil drilling hoses and marine high-pressure oil drilling hoses and marine high-pressure oil conveying hoses.
