This proactive strategy helps maintain the integrity of pipelines and prevent failures.

In #

Line Inspection (ILI):

In #

line inspection, also known as intelligent pigging, is a method of inspecting the internal condition of pipelines by inserting a tool called a smart pig into the pipeline to collect data on defects, wall thickness, and anomalies. ILI is a valuable tool for identifying issues without disrupting operations.
