Pipes To Water Supply System

Below are pipes that are used frequently in the water supply system.

  • Cast Iron (CI) Pipes
  • Steel Pipes
  • Galvanized Iron (GI) Pipes
  • Copper Pipes
  • PVC, Polythene, or Plastic pipes
  • Asbestos Cement (AC) Pipes
  • Concrete Pipes

You should know about above mention Specialised Pipe & Water Solutions in detail so here we have explained them properly below:


  1. Cast Iron Pipes

The following are the main reasons these pipes are used most often in the water distribution system:

  • They are more affordable in terms of cost
  • It is resistant to corrosion.
  • It is extremely durable
  • I. Pipes are made using the following four methods.
  • Horizontally cast (MCware pipes)
  • Vertical casting (pit casting in sand molds)
  • Cast in landlines molds type spun type
  • Centrifugally cast in water-cooled metal molds
  • Horizontal cast C.I. is now a common option. Pipes are no more used.
  • They are popular because of their fine-grained dense structure, uniform thickness, and wide use.
  • To prevent damage, special care must be taken when connecting and transporting these pipes.


  1. Steel Pipes
  • When possible, the use of steel pipes for water supply systems is recommended.
  • Pipes are exposed to extremely high pressure (i.e. Pipes are subject to very high pressure (i.e., 7 kg/cm2)
  • Large diameter pipes are needed
  • Steel pipes are more durable than C.I. and are lighter in weight. pipes.
  • However, these pipes require proper preventive measures to withstand adverse atmospheric conditions.


  1. Galvanized Ion (Gi) Pipes
  • This pipe is used to supply water inside buildings. These pipes are made of wrought steel and coated with zinc.
  • They come in light, medium, and heavier grades depending on how thick the metal is. The thicknesses for a 15mm GI pipe are 2.0, 2.65, and 3.25, respectively, depending on the grade. The medium-grade pipes are generally used in internal plumbing within buildings.
  • I. pipes are mainly made of sockets and screw joints. pipes.


  1. Copper Pipes
  • These pipes are used for hot water installation. These pipes are strong and flexible. They can also be bent easily due to their high tensile strength.
  • Copper pipes can be coated with chromium to improve their appearance.


  1. Plastic, Polythene, Or Pvc Pipes
  • These pipes are increasingly being used for cold water supply in both internal and external plumbing.
  • They are lightweight, non-corrosive, and lower in cost.
  • Use unplasticized PVC (UPVC), or rigid pipes with cold water

PVC pipes are made from plasticized PVC that has been added with rubber.

  • It is less strong and has a lower working temperature than UPVC pipes.
  • Pipes are made of chlorinated PVC (CPVC), which can withstand higher temperatures (up to 120 0) and are used to transport hot water.
  • The wall thickness for pipes that are used in soil or wastewater discharge systems will be greater than the one used for roof drainage.
  • For water distribution at temperatures below 45 0C, rigid PVC pipes can be used.
  • The pipes’ strength decreases with increasing temperatures. The life expectancy of PVC pipes is also affected by ultraviolet radiation and frequent temperature changes.
  • These pipes are more expensive than AC pipes, but they are cheaper than GI pipes.


  1. Asbestos Cement (Ac) Pipes
  • These pipes can be used to drain rainwater from roofs, soil, and waste.
  • They also serve as ventilation. There are two types: one with beading around the socket (WB), and one without. This latter type is more popular than the first.
  • Pipes are available in lengths up to 3 meters.
  • These pipes have two main flaws: they are heavy and break easily.
  • These pipes are less expensive than PVC pipes.


  1. Concrete Pipes
  • For water supply and other purposes, you can choose from unreinforced small diameter pipes or reinforced and prestressed concrete large diameter pipes.
  • For rainwater drainage, small concrete pipes can be used.
  • Major water supply projects usually require large diameter pipes.
