The Process Of Pipeline Construction

By Kathleen Schmidt


Workers involved in working on pipeline often undertake several practices to ensure they are tightly fixed to avoid any leakages. The structures are set up to facilitate transportation of petroleum products such as gasoline to various places. Professionals involved in putting up these routes need to work together throughout the process. Examine the following steps followed during pipeline construction.

The acquaintance of right permits. The procedure will require the initial process of acquiring the relevant permits from the governing departments. Ideally, the development of this sort requires an environmental impact assessment report done by a registered lead expert. All the impacts are reviewed and site visits made to ascertain the need for the project. Then the assessment license is issued out after three weeks.

The process of surveying the route. It is a professional task undertaken by land surveyors. In this case, the routes to be followed by the conduits will need assessment to tell whether the development will be suitable or not. Some of the activities involved when surveying are obtaining contours, getting and measuring soil samples then writing a comprehensive report down. The activity is normally done during the planning phase.

Clearing the plants along the routes. It is the procedure which involves getting rid of all plants and vegetation lying along the way. Give that pipelines are known to transverse through grasslands or away from the residential areas that are dominated by bushes, clearance to pave the way for excavation and appropriate trenching has to be done. The activity can be mechanized or people hired to perform the job.

Digging trenches. This is the process of digging up furrows to the recommended depths to set up the support pillars. It can either be mechanized or done by humans. Use of machines may be more effective as the distances covered by pipelines are quite long. The rate at which mechanization does excavation is higher compared to that of the manual workforce thus aiding into a faster task.

Pipe bending and welding. This involves making appropriate adjustments to the various gauges of metals to fit the contours. It involves the introduction of appropriate machines to perform the activity and fit the pipes firmly. The specialist operating the equipment ought to be well dressed to avoid compromising their safety. It is a faster task that helps cover long distances over a short period.

Lowering in and filling the trenches. Also, once the trenches are ready to the required depths, lowering them follows. Given that the metallic pipes are very heavy, the process requires some form of mechanization. They need to be on the same level to facilitate a free flow of the products by gravitational pressure. In this regard, it involves also taking into consideration the necessary gradient levels.

Decommissioning and restoration. They are the last stages of entire process. The commissioning stage is associated with landscaping which aims at marinating the appeal of the surroundings through either planting trees or grass along the excavated grounds to hold together soils. Erosion is also controlled in the process since winds or water cannot blow off the loose soil particles left out.
