Pipelines construction phase begin after the route selection, environmental permitting, surveying, preparing the right of way, stringing the pipe, easements negotiations, and other pre construction phase have been accomplished.

1. Pipeline Construction and Its Types
http://www.prs-med.com
Pipeline construction process starts with initial planning and the entire construction process
takes up to 17 to 18 months. Initial planning include determining the market need, specification
of pipe and components, land acquisition, environmental assessment, land permitting, public
consultation, pipeline design and route selection etc.
The construction process not only covers the civil work to lay the pipeline, it also has to cover
all the work related to the installation process of the field devices that will support remote
operations. The main purpose of constructing the pipelines is to carry a variety of materials for
residential, commercial and industrial needs.
Pipelines construction phase begin after the route selection, environmental permitting,
surveying, preparing the right of way, stringing the pipe, easements negotiations, and other pre
construction phase have been accomplished. After this pipeline is carefully placed in the pre
dug trench under waterways and roads, and if trenching is involved the trench is filled and post
construction process begins. The whole process of pipeline construction has three different
phases such as pre construction, construction and post construction.
In addition, construction phase includes bending and joining the pipe, positioning and coating
the pipelines, installing valves and fitting and backfilling the trench is done. High side and low
side are two different types of installation which needs to keep in mind while determining the
pipeline route and geography of the pipeline installation.
There are various steps involved in pipeline construction process such as:
Clearing, grading and trenching
Stringing and welding pipe segments
Depositing the pipeline
Backfilling and Testing
Restoring
Types of Pipelines
Depending on its purpose, pipelines are of different types like gathering lines, transmission
lines, distribution lines and feeder lines. Gathering pipelines are the group of smaller
interconnected pipelines forming complex networks and these lines travel short distances
gathering products from wells and then move to other facilities. The purpose of these lines is
the bringing of crude oil or natural gas from several nearby wells to a treatment plant.

2. Transmission lines are also known as transportation pipeline having long diameters, moving
products between cities, countries and even continents. These are energy highways,
transporting materials across the international provinces or within the provinces. On the other
hand distribution lines are composed of several interconnected pipelines with small diameters
used to take the products to the final consumers and are used in local distribution companies to
distribute the materials, whereas feeder lines move products from batteries, processing
facilities and storage tanks in the transmission pipelines. These are used to distribute gas to
homes and business downstream.
In order to construct pipelines, environmental or climatic conditions must be considered which
can affect the construction process like heat and cold both can impact the characteristics of the
pipeline such as its flexibility and joints.
It is necessary to plan first and consider all requirements and the things which can impact and
then start the construction process so that without delay, project has been completed easily.
