| Specifications | Rigid PVC Pipes | Asbestos Cement Pressure Pipes | Galvanised Iron Pipes (G.I.) | Cast Iron Pipes (C.I.) | Economic Advantages of PVC Pipes |
|---|---|---|---|---|---|
| Weight | Light, Pipes weigh 1/6th of CI. & GI. and 1/5th of A.C. |
Heavy | Heavy | Heavy | Saving in handling & transportation cost. Installation is easier. |
| Inside Surface | "Mirror-like" smooth finish |
Smooth | Rough | Rough | Les frictional loss, savings in pumping costs. (Fuel saving) |
| Co-efficient of flow ('C' value) | 150-Remains constant throughout its life | 140 | 100-Decreases over a period of use. | 100-for new pipe 40-50 after 5 to 10 years. | Better flow. More discharge of water |
| Formation of deposits | Absolutely no formation of deposits. Pipe bore remains constant throughout its life | No formation of deposits. | Formation of deposits leading to reduction in pipe bore. | Formation of deposits leading to reduction in pipe bore. | Uniform flow of water throughout. No danger of contamination dueto deposits. |
| Installation technique | Very quick & simple | Time consuming | Involves threading | Cumbersome & time consuming | Reduce installation cost & time. |
| Material cost | Lowest | High | High | High | Greater saving in materials cost. |
| Length | 6 Meter | 3 to 4 Meter | 5 to 6 Meter | 3 to 4 Meter | |
| Effect of Rust | Question of rust does not arise | Do not get rusted | Gets rusted | Rapid rust formation | It is rust proof therefore long lasting |
| Accumulation of Particles forming rust | Very less chances, therefore Diameter of Pipe remains unaltered permanently. | Particles do not accumulate | Rust particles accumulate heavily therefore Diameter gets reduced on long run. | Heavy accumulation of particles, therefore Diameter gets reduced after a period. | Since Diameter remains it gives uniform flow permanently. |
| Life | Lasts a lifetime | Less chances of changing | Gets rusted, so required to be changed after 30 years. | Requires change after 20 years | Investment once- Lifetime Safety. |
| Jointing | Leak proof | Not Leak proof | Not Leak proof | Not Leak proof | Very Quicky |
| Cost | Average | More than PVC | More than PVC | More than PVC | Very low price |
