Building a pipeline is a complex process that requires a great deal of planning. There are several steps along the way and extensive standards and regulations to adhere to. Keep reading to learn more about the process.
Planning and Development
Because of their size and complexity, pipelines are built section-by-section over an extended period of time. Once the route has been determined, and the proper permits have been obtained, construction begins. The process involves:
- Surveying and stakingâ€”Marking the path that the pipeline will take.
- Clearingâ€”Removing trees and vegetation.
- Trenchingâ€”Excavating a trench where the pipeline will rest.
- Stringingâ€”Sections of pipe are placed alongside the pipelineâ€™s path.
- Joiningâ€”Portions of pipe are welded together. Individual welds are tested using NDT or X-Ray inspection methods.
- Coatingâ€”Welded pipe is coated with a special material that resists corrosion and rusting.
- Loweringâ€”Prepared sections of pipe are placed in the trench.
- Valves and fittingsâ€”Check and block valves are installed intermittently along the pipeline for safety.
- Pressure testingâ€”Welds, fittings and valves are subjected to a pressure test. If the pipeline passes inspection, it is granted the certification required to operate.
Technology and Components
Several component stations help the pipeline operate smoothly:
- Supply stationâ€”the beginning of the system where the oil and gas are introduced to the pipe.
- Compressor/pump stationsâ€”located along the pipeline, these stations help keep the liquid moving.
- Block valve stationsâ€”located intermittently along the pipeline, block valves allow pipeline operators to block off a section of pipe for maintenance or repair.
- Regulator stationsâ€”usually located after a hill, they allow operators to release built up pressure.
- Final delivery stationâ€”the terminal or distribution centre where oil and gas will be stored and/or shipped to other locations.
Each component works to help the product move along the pipeline to its final destination. NDT companies like 20/20 NDT use leak detection technology like X-Ray and other types of NDT inspection to ensure proper functioning.
Safety Regulations and Standards
All pipelines operating in Grande Cache, Alberta have to meet stringent safety and technical standards. The National Energy Board (NEB) audits pipelines for signs of cracking, corrosion and other defects to minimize the risk of failures.
Safety standards protect the health of the community and the natural environment. Thatâ€™s why itâ€™s essential to use a qualified NDT company like 20/20 NDT for all of your X-Ray and NDT inspection needs in Grand Cache.
