What are the specifications for the installation of water ball iron pipes?
Trench excavation: the width of the groove should be pressed by the meter: B=D1+2 (b1+b2). Type B: the width of excavation at the bottom of the pipe groove (mm) D1 the width of the outer edge of the pipe structure (mm) B1 - the width of the face of the pipe side (mm) B2 - the support width of the side of the pipe (mm).
Ductile cast iron pipe is characterized by mild, high, thin wall, pressure resistance, impact resistance, corrosion resistance, seismic resistance and other properties. The flexible interface is used for the pipeline interface, and there is a certain elongation and deflection angle. The utility model has the advantages of the raw iron pipe and the steel pipe material, and avoids the defects of iron and steel.
Groove support: according to the groove soil, groundwater, slotted cross section, load conditions and other factors, the design requirements are firm and reliable, to prevent landslides, support, shall not impede the lower pipe and stable pipe.
The T type interface pipe shall be supported by a pier in the vertical or horizontal direction. The size of the pier should be calculated according to the factors such as pipe diameter, angle of rotation and working pressure. 4, the transmission of drinking water, the pipeline should not pass through the poison contaminated areas, such as the need to pass through, should take protective measures.
