These service pipes are made from different materials as classified below.Copper pipesGalvanized iron pipesPolythene pipesLead pipesCopper PipesWhen ground water is highly corrosive to metals then copper pipes are used. Copper have high corrosive resistance when compared to other pipe metals and they also have considerable strength, reasonable ductility. They are available in long lengths in the market. They can bare high pressure so; these pipes are also used for industrial purposes for heavy flows.There are two types of copper pipes are available namely HEAVY GAUGE and LIGHT GAUGE pipes. Heavy gauge pipes are used where pressure is very high, like as the leading pipe from distribution main, for large flows etc. light gauge pipes are used when the pressure does not exceed 0.15N/mm2 that is for internal domestic pipesGalvanized Iron PipesWhen compared to copper pipes, G.I pipes or steel pipes are very economical. But they corrode easily in soft and acid waters. In the other case galvanized iron pipes are much stronger than copper pipes so, we can use this pipes in places where chance of corrosion is less or in hard water areas.
