API682 as a standard set forth by the American Petroleum Institute (API), encompassing mechanical sealing devices utilized in industries like oil & gas and chemical processing. Its primary goal is to ensure the efficient operation of mechanical seals within rigorous industrial environments, minimizing leaks while boosting equipment efficiency and safety.

The API 682 piping plans entail specific configurations or arrangements of piping, cooling reservoirs, control devices, and instrumentation around the fluid flow and circulation surrounding the mechanical seals of pumps. These flushing plans are tailored for different operating conditions and are assigned specific numbers to ensure the safety, efficiency, and reliability of the mechanical shaft seals used in pumps.
