Definition - What does Pipe Segment mean?

Pipe segments are pre-determined lengths of pipe used in the pipe ramming technique for the purpose of ramming pipes into the ground for the installation of pipelines. Usually, pipes are driven in a continuous run, but for places where space is limited, the process is completed by short ramming sections.

Pipe ramming is a trenchless technique that is used for the installation of pipelines under embankments, railway crossings, rivers and under environmentally sensitive areas.

Trenchlesspedia explains Pipe Segment

The length of pipe segments is determined by the contractor depending on the space available for the insertion pit. The lengths may vary between 10 feet to 60-feet, with the optimum length considered to be between 20-feet to 40-feet. As each pipe segment is installed, the ram is pulled back to its original position. A new segment is placed in position behind the installed pipe and the ramming process is started again.

The pipe segments are either welded together or interlocking pipe joining systems are used that have mechanical press fit joints, which are quick to install and are strong. Welding pipe segments take a long time and need to be strong enough to withstand the force from the percussive ramming that will push the pipe further.
