Hazards Of Corrosion Inside Pipes

The decrease of water supply capacity, the increase of water supply power consumption, the generation of "ring rust scale" in the pipeline, the reduction of effective diameter, the increase of water transmission resistance, the increase of water head loss in pipeline operation, resulting in a serious shortage of water consumption and water pressure. Rust and scale greatly increase the friction of the pipeline, in order to ensure the normal water supply, meet the production and living needs of the conditions, the water plant water pump head must be increased, the power consumption of water supply will also increase, resulting in a great loss of economic benefits of water supply enterprises.

Polluted water quality The water quality of the water supply company is good, especially the water turbidity is only 0.5-1 degrees, but after the water supply with such low turbidity is transmitted through the pipeline, due to the corrosion of the inner wall of the pipeline, part of the Fe(OH)3 can be floating in the water, and 2% to 3% of the rust scale can be dissolved in the water (physical and chemical identification results), so that the water is subject to secondary pollution. The "red water" phenomenon appears. Especially when the flow rate and flow rate in the pipeline change, there will be a large number of "red water" or even "black water", resulting in water quality accidents.
