What is recommended following the chemical cleaning of a line that was in service?

• A. A pressure test.
• B. A visual inspection.
• C. Repainting the pipeline.
• D. A system flush.

Answer: (A)

Following the chemical cleaning of a line that was previously in service, conducting a pressure test is a recommended practice. This is crucial to verify the integrity of the piping system after cleaning. Chemical cleaning can sometimes lead to unexpected changes in the pipes, such as the potential for stress corrosion cracking or leaks that were not apparent prior to the cleaning process. A pressure test serves to ensure that the system can handle operational pressures without any leaks or failures, confirming that it is safe to return to service. While visual inspection is important and can complement the process, it alone cannot provide the definitive assurance that a pressure test can offer regarding the system's capability to withstand operational pressures. Repainting would typically be a maintenance activity unrelated to the immediate concerns after cleaning, and a system flush, while useful for removing debris or leftover cleaning agents, does not address the structural integrity of the piping material. Thus, the pressure test stands out as the most critical action following chemical cleaning to ensure the safe operation of the line.
