API 622 - Type Testing of Process Valve Packing for Fugitive Emissions

API 622 specifies type testing requirements for compression packing used in gate, globe, and other rising-stem valves to qualify packing sets for fugitive emissions service - complementing API 641 for ball valve stem seals.

What is API 622?

API 622 (API 622 - Type Testing of Process Valve Packing for Fugitive Emissions) is an industrial valve standard issued by American Petroleum Institute (API). API 622 defines type testing procedures for valve packing systems to demonstrate compliance with fugitive emissions requirements.

Overview - API 622

Scope

API 622 defines type testing procedures for valve packing systems to demonstrate compliance with fugitive emissions requirements. The test uses a 2-inch Class 600 gate valve as the reference valve, subjected to 1,500 thermal cycles while monitoring helium leak rates at the stem packing. Packing that passes API 622 is qualified for service in valves where fugitive emissions control is required by environmental regulations.

Vajra Industrial Solutions manufactures and supplies valves engineered to comply with API 622, each delivered with API 622 qualification certificate with packing manufacturer and Test report with cycle data and leak measurements as standard.
