How to do anti-corrosion of buried metal water supply pipeline?
Underground pipeline anti-corrosion must first rinse the pipe rust paint, and then rinse anti-corrosion ointment, wrapped glass fiber cloth, and then rinse the anti-corrosion ointment on it.
When the flow of a fluid is known, the size of the pipe depends on the allowed velocity or allowable frictional resistance (pressure drop). When the flow rate is large, the pipe diameter is small, but the pressure drop increases. Therefore, when the flow rate is large, the infrastructure investment of the pipeline can be saved, but the energy consumption of the power equipment such as pumps and compressors is increased. In addition, if the flow rate is too large, there may be other adverse factors. Therefore, the diameter should be determined according to the construction investment, operating costs and other technical factors.
: outdoor pipeline pipeline is pipe, pipe fitting and valves connected into the conveying gas, liquid or solid particles of fluid device. Because of its unique characteristics, pipeline is widely used in many industries and fields. Pipes are widely used, mainly for water supply, drainage, heating, gas supply, long-distance transportation of oil and gas, agricultural irrigation, hydraulic engineering and various industrial installations.
