From the new water intake point of the domestic water plant to the water plant, seamless pipelines are used for water supply along the edge of the forest area. It has been used for 15 years. The water supply pipelines have different degrees of corrosion and scaling. When the water supply pipelines are damaged and need to be repaired, there will be fires. Operational safety hazards.After discussion by technicians, it was proposed to use polyethylene polymer pipes with better corrosion resistance and pressure resistance to replace the original seamless pipes for water supply. At the same time, the direction of domestic water supply pipes was re-planned, which not only improved the quality of drinking water from the source. , It also eliminates the hidden danger of fire safety in forest areas.
