Leak Trough Line (I)

Brand: Leak

The leak trough line (LTL) is a crucial design consideration for underground pipelines. It refers to the depth below the ground surface where the pipeline's hydraulic performance begins to degrade due to soil infiltration. When the pipeline surface comes in contact with soil, the permeation of water causes a head loss in the pipeline system, which affects the flow rate and increases pumping costs.The leak trough line is dependent on several factors, such as soil type, hydraulic characteristics of the pipeline material, and water content of the surrounding soil. Generally, clay soil tends to have a lower LTL than sandy soil due to its lower permeability. The LTL can also vary based on soil compaction and pipeline installation methods.Determining the LTL is essential for pipeline design because it helps to optimize the pipeline's layout, depth, and profile to minimize water intrusion. Proper pipeline design, such as utilizing a double-walled system or a cathodic protection system, can further help to mitigate corrosion and prevent leakage in the LTL region. By minimizing water intrusion, the LTL helps to maintain the pipeline's hydraulic efficiency and prolong its service life, saving costs for maintenance and repair.
