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:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
