  • River dredging hose

    There are two main types of flanged dredging hoses: large-diameter flanged dredging hoses and steel wire flanged dredging hoses. Flange dredging hoses are mainly used in cement bulk tankers, ship cement suction and discharge dual-use, etc. With abrasion resistance, temperature resistance, good acid and alkali resistance. For dredger row (suction), the working pressure is 0.4-0.5Mpa. Flange joints are available according to design requirements. The diameter of large-diameter suction and discharge hose is between 200-860, and the outside diameter is 200. The nominal inside diameter is about 205, the thickness of the inner rubber layer is 10, the flange outer diameter is about 320, the flange outer diameter is t1, the joint The thread thickness is 6 cm and the center circle diameter is 280. The number is 8 and the diameter is 23. Large-caliber steel wire hose is used for marine high-pressure oil transportation hose for the transportation of submarine natural gas, petroleum and other media. The marine high-pressure oil transfer hose consists of a steel wire wound skeleton layer and internal and external oil-resistant and corrosion-resistant synthetic rubber. Hose specifications are 2sp-152-8, 2sp-203-8, 4sp-254-16, 4sp-305-16 and so on. The inner diameter is between 152-305, and the outer diameter of the steel wire layer is 173-341. The outer diameter of the hose is between 180-350. The maximum working pressure is 16mpa, the maximum detection pressure is 32mpa, and the maximum burst pressure is 48mpa. The flanged dredging hose meets the needs of long-distance transmission of hydraulic oil in large coal mines, and has very good application and development prospects. Pressure of flanged dredging hose: The specified working pressure of flanged dredging hose is not less than the maximum system pressure. Normal oil drilling high pressure hose can be used only in rare cases. He is only allowed to increase by 20%; frequent use of torsion reduces by 40%. Temperature, fluid temperature, and ambient temperature are both stable and transient. The large-diameter hose must not exceed the limit temperature. The recommended heat resistance is higher or lower than the hose. The hose can reduce performance, cause damage to the hose, and cause leakage. Fluid compatibility: The fluid of large-diameter hoses should comply with the "usage" regularity of product samples. The product characteristics of high-pressure steel wire braided hoses should ensure the management and safety of life when specified. Connection end: Because the nut is convenient to connect, low cost and widely used, the vibration is large under the allowable conditions. The problem of nut tightening should be fully considered, and the connection should be flanged.
