16 Types of Pipelines and their Construction Method (1)

A pipeline is a system of pipes designed to carry fluids such as oil, natural gas, or other petroleum-based products over long distances, often underground. It is a very important part of the modern civilization that has now been used for millennia for the movement of water.

Pipelines typically cost more than roads or open channels. It takes years and requires many surveys and studies and plans to be completed to develop a comprehensive plan that addresses the societal, developmental, environmental and safety considerations necessary to build the pipeline.

However, they can offer reductions in cost based on shorter and more direct routes than roads or open channels. Construction of pipelines, especially for large scale water-supply or petroleum projects, are large multi-disciplinary activities which involve the investment of large amounts of cash and other resources.

There are different types of pipelines classified on the basis of manufacturing material, transported substance, and function of the pipes.

Types of Pipelines

1. Steel Pipeline 

Steel pipes are employed for the water pipelines. Large diameter pipes can be manufactured from steel and can be extended over large distances.

2. Cast Iron Pipeline

Cast iron pipes are mostly produced from gray cast iron for which coatings and linings are applied so as to improve corrosion resistance. These types of pipes have been widely used in the past.

However, today, ductile iron pipes which are superior to cast iron pipes are being widely used.  Such a pipeline type is suitable for the transmission of water, gas, and sewage.

3. Plastic Pipeline

It is generally used for the transmission of water over long distances. Plastic pipes have great resistance to abrasion, chemical influence and are easy to handle. Added to that, their light weight makes it easy for the workers to lay and align as per the need. However, they have low tensile strength and show poor performance during temperature fluctuation.

4. Concrete Pipeline

Concrete pipe is manufactured from welded sheet steel with jointing surfaces and concrete. It is particularly suited to large diameter pipelines extending over great distances. Concrete pipes are an appropriate choice for the transmission of water.
