Pipeline Construction Process After Council Permits are Granted

December 4, 2019

Pipelines play a crucial role in every property. Be it water or crude oil, pipelines can affect the way we manage our properties and maintain the necessary supply to stay functional. And since pipelines are critical to properties, the construction of the pipelines requires necessary steps before proceeding to the grand plan.

Construction works usually begin with the arrangement of necessary permits and documents. For pipeline construction, the council permits must be granted first before you proceed with the next steps. Once your pipeline construction and design is completed and approved, you must then do the next steps:

Meeting with Landholders - Meeting with landholders is necessary so that you can discuss and agree the bounds and access of their properties when the pipeline construction starts. Once the pipeline is complete, they must also agree about the underlying effect of the pipeline to their vicinities.

Conducting Survey and Fencing -The pipeline route must be surveyed first before initiating the construction. Moreover, all routes that the pipeline will cover must be fenced to restrict non-personnel from entering the area.

Clearing the Area - Bulldozers, diggers, and graders will be sent to the area where the pipeline will be installed. They are responsible for clearing the area so that the construction will begin. Top-soil and vegetation will be set aside so that the firm can restore them after the pipeline is completed.

Stringing - All pipes will be transported to the area where the construction of the trench will commence. The pipes will be laid end to end next to each other. 

Bending - If there is a need to bend the pipe to match the contours of the land and the route of the pipeline, then specialized machinery will come in. This part is important so that the whole pipeline system can function fully without any problems.

Welding - The connected pipes from the stringing procedure will now be welded together. This welding process will be tested and examined to ensure top of the line quality.

Joint Coating - After the pipes are welded, the areas with welding marks will be cleaned. They are then coated to protect them from any possibility of corrosion and external damage.

Trenching - Excavators, diggers, and any specialized trenching machines will now dig to make a trench for the pipeline.

Lowering In and Padding - Once the trenches are set, it is now time to lower the pipes. Specialist equipment like side booms will lower the pipes into the trench. After the pipes are set, they will be covered by fine-grain material to serve as padding. This padding will protect the pipeline coating from any harmful materials. 

Backfilling - The previously excavated subsoil material will then fill up the trench. Both the topsoil and the subsoil must still be separated distinctly as the coating of the pipes might get destroyed with one simple mistake. The subsoils will limit the settlement of the trench throughout the life of the pipeline. 

Hydrostatic Testing - Before starting the operations of the pipeline, the system will be pressure tested first with water. This type of test will see if the whole pipeline system is ready to be operated.

Restoration - All areas involved in the project are reinstated according to their existing landforms. Permanent erosion control structures are created so that both the pipeline system and the properties around won’t get damaged when erosion occurs. The preserved topsoil will be applied again all over the construction site. Signs will also be placed to remind the existence of pipeline underneath.

All these processes contribute to the success of the pipeline for the convenience of the whole community. If you want to know more about pipeline construction and how it works, you can contact us now at Metro Pits.
