Spheroidization of Yin and Yang of nodular casting' target='_blank'>cast iron pipe ink area is how to form 1. In the middle of the ductile iron pipes per tube parts proper covering, pipe installation should be flat, should be in a straight line between the pipe, if it comes to the tilt Angle, be careful. It is the responsibility of the water supply enterprise. If need to borrow the pipe installation, in the corner with the pipe itself cannot be satisfied. Makes a graphite spheroidizing, reduce stress concentration, pipe material has high strength, elongation, impact resistance, corrosion resistance, good sealing, etc advantages; 2. Ductile iron pipes extension pipe fittings may be adopted, with a single wire for installation. Microbial activity in biofilm internal environment changes, such as oxygen concentration, pH value, pH, etc. , to form the metal surface area of Yin and Yang, cause galvanic cell reaction. Is a better interface form nodular cast iron pipe. 3. Ductile iron pipes according to need to borrow turn Angle, after calculation of pipe socket after cutting the bevel, ductile cast iron pipe and can ensure the safe use. Along the entire aprons with the hand press it again, or use the rubber hammer to hit, and the average card in the slot. Nodular cast iron pipe bending section in the use of pipeline interface by corner when installation, pipe should be installed in a straight line, and then turn to the required Angle. 4. Use cement mortar lining so as to improve the pipeline environment, the progress of the water supply capacity, reduce the energy consumption; Nozzle using the flexible interface, and the pipe itself has a larger elongation (> 10%) , make the pipe flexible is better.
