Types Of Pipes
The types of pipes commonly used in the water distribution system are described below.
1- Cast Iron Pipes
Cast iron pipes or CI pipes are broadly utilized for distribution of water because they are less expensive, corrosion-resistant, and long-lasting. CI pipes are mainly produced by the following four techniques.
1- Horizontally cast ( MC ware pipes)
2- Vertically cast ( Pit cast in sand moulds)
3- Centrifugally cast in sand lines moulds spun type.
4- Centrifugally cast in water-cooled moulds.
Uses of horizontally cast CI pipes are presently pretty much outdated, that’s why they are infrequently produced these days. Centrifugally cast pipes are most widely used because they have a more grained dense structure and uniform thickness. Generally, CI pipes are 3-6 m long, so much heavy, and require extra care to avoid damaging while transporting and creating connections
2- Steel Pipes
Steel pipes are utilized in water mains circumstances where the pipes are going through very high pressure ( More than 7 kg/cm2) and required large diameter pipes. These pipes have greater strength and less weight than CI pipes. Satisfactory treatments should be given to maintain antagonistic climatic conditions.
3-Galvanized Iron Pipes
Galvanized pipes are also known as GI pipes are fashioned steel pipes with zinc coating. GI pipes are mostly utilized for water supply and service connections.
4- Copper Pipes
Copper pipes are most commonly utilized in hot water supply establishment. Some features of these pipes are as follows:
1- They possess high tensile strength.
2- They can be bent easily.
3- Copper pipes can be used in the thin wall.
Copper pipes are sometimes chromium-plated to enhance their appearance and to match with the chromium-plated water supply fittings.
5- Polythene Pipes
Polythene and PVC pipes are being utilized progressively nowadays for cold water supply inside and outside works. These pipes are lightweight, cheaper, corrosion resistant, and require no threading for making any connections.
Besides these, there are other pipes commonly used for water distribution such as asbestos cement (AC) pipes, reinforced concrete (RCC) pipes, prestressed reinforced concrete (PSC) pipes etc. The selection of the types of pipe for utilizing any purposes is adopted according to the design criteria, material availability, cost, and other comparative variables.
