API 20F BSL -2/3
Description of Material
The American Petroleum Institute (API) develops operational standards for equipment & hardware used in petroleum, natural gas and petrochemical applications with the aim of enhancing operational and environmental safety, efficiency and sustainability.
API 20F is a specification developed by the American Petroleum Institute (API) that outlines the requirements for corrosion-resistant bolting used in the petroleum and natural gas industries.
There are 2 bolting specification levels (BSL 2 & 3) and the criticalness of the fastener increases with the BSL number and therefore, so does the stringency and volume of the testing and inspection requirements.
The following Bolting Material grades are covered by this standard:
- API 6ACRA 718 (120 KSI)
- API 6ACRA 725 (120 KSI)
- API 6ACRA 925 (110 KSI)
- ASTM A453/A453M 660D
All products shall meet the requirements of the referenced ASTM specification and the modifications specified by the API 20F standard and the relevant bolting specification level.
