Three Ways Operators Check for Pipeline Integrity

The pipes used by oil and gas firms need to be maintained with diligence. Regular maintenance and monitoring are essential to preventing leaks, fractures, and other risks during a pipeline's lifetime. Pipeline operators can detect problems before they become costly and hazardous by using various testing techniques. The top three pipeline testing forms operators use are ultrasonic, hydrostatic, and magnetic flux tests.

Fremont, CA: The pipes used by oil and gas firms need to be maintained with diligence. Regular maintenance and monitoring are essential to preventing leaks, fractures, and other risks during a pipeline's lifetime. Pipeline operators can detect problems before they become costly and hazardous by using various testing techniques. Pipeline operators may use the following resources and methods to assess the integrity of their pipes and encourage more effective preventative maintenance, ranging from magnetic flux instruments to pipeline pressure testing equipment.

Ultrasonic Tests

Over time, walls may become thin and lose their integrity due to corrosion and other types of deterioration. Determining the precise thickness of a pipe wall is essential for assessing the kind of pressure it can withstand and the degree of structural support it can provide to other pipeline elements. Ultrasonic testing, which employs high-frequency sound waves to travel inside the pipe, allows pipeline operators to ascertain the thickness of a pipe wall. Afterward, experts will gauge the sound wave passing through and reverberating off the pipe walls. Using this data, they can ascertain the pipe walls' precise thickness and locate regions exhibiting corrosion or other flaws.

Hydrostatic Tests

Pipeline testing is frequently conducted using hydrostatic tests. To perform a hydrostatic test, pipeline personnel fill a separate pipe segment with water and pressurize it to a slightly higher pressure than usual. After maintaining the pipeline at that pressure, workers record the volume and pressure inside the pipeline. Operators can identify the presence of a leak in the pipe if these levels suddenly drop. They may then check the pipe for defects, such as cracks, that are the issue's root.

Magnetic Flux Tests

Magnetic flux tests assess the amount of metal lost due to corrosion, gouges, and other problems using magnetic flux leakage instruments. During a magnetic flux test, pipeline workers use this equipment to create a transient magnetic field within the pipe. Workers watch the magnetic field for changes as the magnetic flux tool travels through the pipe. The magnetic field will be consistent if the pipeline is ideal and has no flaws. Any abnormalities that alter the magnetic flux's distribution indicate flaws or metal loss. Pipeline workers may discover problem locations and choose the most effective approach to remedy them using the magnetic flux tool's sensors to quantify these abnormalities.
