Which of the following elements is NOT a part of ensuring cleanliness in a piping system?

Adding lubricants for smooth operation is not directly related to ensuring cleanliness in a piping system. The primary goal of cleanliness in such systems is to prevent contamination that can interfere with the flow and quality of the fluids being transported. Contamination monitoring, regular inspections, and documenting cleanliness standards are all integral components of maintaining a clean system.

Contamination monitoring involves checking for foreign particles or substances that could compromise the integrity of the system. Regular inspections ensure that any potential issues regarding cleanliness are identified and addressed in a timely manner. Documenting cleanliness standards establishes a benchmark for what is considered clean, guiding maintenance and operational practices.

While lubrication is essential for optimal functioning and to reduce friction or wear in moving parts, it does not pertain to the cleanliness and contamination control aspects necessary for the integrity of the piping system.
