What is the Objective of Equipment and Piping Inspection?

"To achieve economic & un-interrupted
operation of plant by ensuring availability of safe and reliable equipment."

To avoid failures of equipment and piping to facilitate uninterrupted
running of plants.

To ensure safety in the plants.

To increase profitability.

Inspection” refers to integrity assessment of various already existing
equipment and piping in the plant.

It also refers to monitoring of critical operating parameters of the plant / equipment which are directly or indirectly related to deterioration of equipment & piping Integrity.

Great importance is being given to “Inspection” in refineries &
petrochemical industries as these plants are vulnerable to corrosion
& metallurgical deterioration due to handling of corrosive liquids /
gas at high temperatures and subsequent risk of very high hazards.
