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.
