API Q1 Certification & API-20E / API-20F Licences


Energy Bolting has been assessed by the American Petroleum Institute and we are proud to announce achieving certification to API Q1.


The award of API Q1 demonstrates that Energy Bolting meets high standards of manufacturing and quality management.

 

Energy Bolting is now licensed to mark bolting with the API Monogram:

API 20E (BSL 1,2,3) and API 20F (BSL 2,3)


API 20E and 20F specify requirements for different bolting specification levels (BSL). The BSL designations define different levels of technical, quality and qualification requirements.

The highest criticality level (BSL-3) is reserved for applications where bolting failure is not an option.

API 20F Licence Number: 20F-0048
