Stringing

Once the pipeline's path has been cleared sufficiently to allow construction equipment to gain access, sections of pipe (or “joints”) are laid out along the intended path, a process called 'stringing' the pipe. Individual pipe joints are commonly 40 to 60 feet long, and are specific to their destination.

Trenching

Pipelines are typically installed below ground to allow for continued use of the land surface and to protect the pipeline.

Track-mounted backhoes or rotary wheel ditching machines are typically used to excavate the pipeline trench. These trenches are typically 5 to 10 feet deep, depending on the size of the pipeline to be installed and other conditions. Regulations require the pipe to be at least 30 inches below the surface.
