Advantage
Strong corrosion resistance, good pressure and bending resistance, convenient joints, water flow, no odor, no harm to health, etc.
Details
Application
1. Trench excavation
The width of the groove bottom should be calculated as follows: B=D1+2(b1+b2)
Where: B—the width of excavation at the bottom of the pipeline trench (mm) D1—the width of the outer edge of the pipeline structure (mm) b1—the width of the working surface on one side of the pipeline (mm) b2—the width of the support on one side of the pipeline (mm)
2. Groove support
According to the trench soil quality, groundwater, slotted section, load conditions and other factors, the design is required to be firm and reliable, to prevent collapse, and the support shall not hinder the down pipe and the stable pipe.
3. The buttress shall be provided at the turning point of the T-shaped joint pipeline in the vertical or horizontal direction. The size of buttress should be determined by calculation according to factors such as pipe diameter, rotation angle, working pressure, etc.
4. When transporting drinking water, the pipeline should not pass through the poisonous contaminated area. If it must pass, protective measures should be taken.
5. All the ductile iron pipelines connected by sockets must be provided with buttresses after calculation. Refer to the National Building Standard Design Atlas 03SS505 "Flexible Joint Water Supply Pipeline Buttress".
6. The outer anti-corrosion coating of ductile iron pipes should be galvanized and epoxy asphalt coatings or coatings with higher requirements according to the soil conditions of the pipe application site.
7. After the pipeline is installed and the pressure test is qualified, it should be rinsed with low chloride ion water and disinfected with 0.03% potassium permanganate aqueous solution.
