Galvanized Iron Pipes had been in use for past few decades for distribution of portable water supply. These pipes are corrosive, reduced flow with passage of time- choked lines as a leakage due to galvanic action and corrosion. SO that Environmentalists and Public Health Engineers all over the world were in search of proper replacement to over come. uPVC Pipes have replaced Galvanized Iron Pipes due to following reasons:
| Parameters
| uPVC Pipe
| Galvanized Iron Pipes(G. I.)
| Benefits of PVC Pipes
|
|
| Weight
| Light
| Heavy
| Saving in Handling & Transportation Costs, Installation is easier.
|
| Inside Surface
| Smooth Finish
| Rough
| Less Frictional Loss, Savings in Pumping Costs,(Energy Saving)
|
| Co-efficient of friction.
| Remains constant throughout its life.
| Decreases over a period of use.
| Better flow.More discharge of water.
|
| Resistance of corrosion
| Good resistance to even strong acids, alkalies or salt solutions.
| Poor
| Longer life of the pipe. Low maintenance and replacement cost.
|
| Formation of Deposits
| Absolutely no formation of deposits. Pipe bore remains constant throughout its life.
| Formation of deposits leading to reduction in pipe bore.
| Uniform flow of water throughout.No danger contamination due to deposits.
|
| Installation Techniques
| Very quick and simple.
| Cumbersome and time consuming
| Reduce installation cost and time.
|
| Material Cost
| Lowest
| High
| Greater saving in material cost.
