LIFE CYCLE OF DI WATER PIPELINE
Every living/nonliving thing has a life cycle. Life cycle is a very important thing in construction work because all construction works start with a huge investment. So constructed structure must provide service for a certain period of time. The service life of structure widely depends on it's construction method, quality of work, actions on it during service life, environmental effects, changes done during it's service life, regular maintenance (not major repair). To know about the life cycle of water pipeline first I want say something about the construction material of pipeline. As we discussing about the life cycle of DI (Ductile Iron) pipeline so here I will write about Ductile Iron. Ductile iron also known as ductile cast iron as it is advanced form of cast iron. Ductile iron retains not only all cast iron qualities but also provides more strength,toughness and ductility. The chemical composition of ductile iron is carbon, silicon, manganese, magnesium, phosphorus,
