Sewage pipes that are made of steel are able to sustain high pressure or gravity. Also, they are resistant to corrosion and minimize the embedded needs.In the water well, casing is done to provide the support and to avoid unconsolidated sand, gravel and the loose rock fragments from falling off the wall of the well. This is basically done to avoid the destruction of the well shaft. The basic purpose of well is that it provides easy access to aquifer. Once a well is constructed for the pumping system, it then acts as the conduit. It brings out the water from aquifer at the surface. Because of the high durability, strength and corrosion resistance, steel casing has been the most preferred material for the water wells. Also, steel casing has the ability to withstand very high temperatures that is caused by curing cement plaster.
