Guided Wave Pipeline Screening

Oil leaks are one of the main issues faced by the oil and gas sector with more than 30% of the pipeline hazards caused by corrosion. In guided wave pipeline screening, the guided waves are discharged by active sensors that reproduce along with the pipeline structure under inspection. At each break that the guided wave meets, an echo is reflected and apprehended by sensors.

The theory of Risk-based Inspection is built upon the concept that the risk of failure can be assessed in connection with a level that is acceptable, and inspection and repair used to assure that the level of risk is below that acceptance limit.

Standard Application:

• Seamless, longitudinally or spiral welded pipe types.
• Pipe size 1 – 72 inches.
• Surface temperature – 40°C to 120°C (diameter < 10″) or -40°C to 80°C (diameter >8″).

Common Pipe Screening Applications include:

• Evaluation of insulated pipe for external or internal corrosion without removing the insulation (other than at the test positions).
• Screening of pipe in racks with minimal access requirements.
• Evaluation of inaccessible regions like cased road and dike crossings.
• Screening of pipe passing through bund walls.

Benefits of our Guided Wave Pipeline Screening:

• Evaluates lengthy pipes quickly.
• Examines 100% of the pipe wall.
• Identifies corrosion in insulated and buried pipelines.
• The test can be conducted at high temperatures without taking the pipe out of service.
• Capable to detect the metal loss (internal or external) and planar defects at long range.
• Only 1% loss of cross-section in ideal conditions (but is ideally set at 5%).
