Types of Water Supply Pipes

Rate this project

Pipes transport gas, hot and cold water, and other liquids securely from one location to the other. Pipes of several kinds are utilized in various situations. The types of pipes are chosen based on their utility and appropriateness, as well as their cost. Types of Water Supply Pipes will be covered in this post.

Various Types of Water Supply

The pipes listed below are amongst the most commonly used and finest pipes for plumbing and water distribution:

  • Cast Iron
  • Galvanized Iron
  • Wrought Iron
  • Steel
  • Copper
  • Plastic
  • Asbestos Cement
  • Concrete
  • Vitrified Clay

Some of these pipes are discussed below.

  1. Cast Iron– Owing to its excellent corrosion tolerance and extended life, cast iron pipe is frequently utilized in municipal water distribution networks. Cast iron pipes are produced from pig iron. The diameter of these pipes typically ranges from 5 cm to 120 cm. Considering normal settings, a cast-iron pipe can last up to 100 years. A pipe segment is typically 12 feet long, although a length of up to 20 feet can be acquired.
  • Galvanized Iron– Mild steel sheet is used to make G.I pipes. Welded Seam Type is the length-wise junction. Inside a structure, G.I pipe is employed to provide water, gas, or other fluid. Pipes of this kind range in diameter from 12 mm (0.5 inches) to 15 cm (6 inches). They come in six-meter (20-ft) lengths. This pipe is ten years old on average. Such pipes are light and affordable. Alkaline and acidic waters have a negative impact on such pipes.
  • Wrought Iron-Such pipes are similar to G. I. Pipes. It may also transfer liquids like water, gas, and other fluid from one area to another. The sole distinction between a wrought iron pipe and a G.I pipe is that wrought iron pipes are produced by soldering wrought iron sheets together. Pipes that are seamless are also manufactured. Such pipe has a lower weight. This pipe is simple to cut, thread, and bend.
  • Steel Pipe-Steel pipes are employed to transport water, gas, or other liquids under stress from one location to another. Steel sheets are used to construct these pipelines. Small pipes feature a hidden welded connection that runs the length of the pipe. The joints on large pipes are either riveted or welded. After that, the pipes are immersed in a zinc solution. This process is known as galvanizing, and it is used to keep pipes from corrosion. Pipes of this type often range in age from 25 to 50 years.
  • Copper Pipe-The diameter of copper pipes are small. These pipes are long-lasting because copper doesn’t rust. However, because copper is so expensive, it is only utilized in a few areas. Hot water or steam is usually carried through these pipes. Even at extreme temperatures, they do not shrink or droop. Copper is a non-corrosive metal. As a result, copper pipes are easily bendable. These are connected by Flanged Joints or Union Joints.
  • Plastic Pipe-Water, acidic water, and alkaline water are all transported by these pipes, which comprise rubber and PVC. Using hot water is not encouraged. A thread junction or a solution joint is used to link such pipes together. These pipes aren’t corroded in any way. They’re not too heavy. Cutting, bending, and jointing these pipes is simple. Electric current is well-resisted by such pipes.With rising temperatures, they become ineffective. When tempered by a nail, for example, they become worthless.
  • Asbestos Cement-Asbestos pipe is comprised of asbestos, silica, and cement, which are pressed together to form a thick, homogenous material with high strength. Asbestos fiber is fully incorporated into the cement and acts as a reinforcement. This pipe comes in sizes ranging from 4 to 36 inches and lengths of 13 feet. The pipe comes in a variety of grades, the toughest of which is designed to withstand internal pressures of up to 200 psi.

Best Pipes for Underground Water Supply

Even though there are numerous possibilities for underground water pipelines, HDPE and PEX pipes are the most prevalent. These corrosion- and rust-resistant pipes are excellent for operating an underground water line.HDPE pipes are non-toxic, have no flavor, and are regarded as a sustainable building component. PEX pipes are long-lasting, flexible, and capable of withstanding high pressures.


Water supply pipes come in a variety of shapes and sizes, and they are used to transfer water from one location to another. Each Types of Water SupplyPipe has its unique properties, and these characteristics dictate its use. This article has discussed the unique aspects of each type of pipe.
