Innovations from the new API 682 standard for mechanical seals and supply systems

摘要

Nearly six years of work went into the update of the API 682 mechanical seal standard, due to come into force shortly. Since its introduction in 1994, API 682 has become the standard, setting the global tone for the procurement and operation of seal and supply systems for centrifugal pumps in the oil and gas sector, as well as in (petro)chemistry. The objective of API 682 is a continuous operation of the seal system for at least three years (25,000 operating hr, subject to the legally stipulated emission values, or for maximum "Screening Value" of 1,000 ppm volume, EPA method 21), increased operational reliability and simplified maintenance.
