Conversion from traditional component seal to API type cartridge seal
Many Hydrocarbon processing and tank storage complex’s were built over 4 decades ago and generally fitted with traditional single component seals that don’t meet today’s API standards.
API 682 was first published in 1994 and intended for both new and retrofit equipment in hazardous, flammable, and/or toxic services. The Standard specified ‘all seals regardless of type or arrangement shall be of cartridge designs without hook sleeves. However many pumps, even today, are still fitted with historic legacy component seals.
