Why is it important?
The harsh environments seen in oil and gas exploration demand high-quality and dependable fasteners safeguard against the release of hydrocarbons into the atmosphere.
Compliance to API 20E and 20F cannot be “inspected into” commercially produced products post-manufacturing. Bolting specification levels (BSL) in 20E and 20F define the increasing levels of severity in the application being used and the rigorous controls required in technical, supply chain management, testing, and qualification processes. Nexus manufactures to BSL-1 and BSL-2.
What sets the product apart from commercial bolting?
- Material – Extensive evaluation and monitoring of our raw material suppliers.
- Supply Chain – Suppliers performing processes on 20E and 20F bolting are expected to maintain rigorous quality standards, and to ensure this Nexus performs onsite technical audits to monitor their compliance.
- Laboratory Testing – All raw material testing is completed by an ISO/IEC 17025 accredited laboratory. For BSL-2, all mechanical property tests performed by the raw material supplier must be re-tested by the bolting manufacturer.
- Marking & Traceability – heat lot traceability maintained and BSL Level, material grade, and API license number identified on all parts and/or packaging.
- Change Management – All suppliers and process control equipment used must be well documented and controlled in qualifying a bolt to API 20E or 20F. When there is a change in the supply chain or manufacturing process that could affect the quality or integrity of the product it must be re-qualified by having all inspection and testing including independent lab testing re-performed.
Where is it used?
API 20E and 20F compliant bolting is now mandatory for many products being manufactured to API specifications. Our API 20E and 20F bolts meet industry standards and global management system specifications. You can identify such bolts as they are marked with the API monogram. It is intended that this bolting be used in surface equipment, subsea equipment, and API specifications such as:
- Blowout Preventers
- Other HPHT Equipment
- API 6A
- API 6D
- API 6DSS
- API 16A
- API 16C
- API 16ST
- API 17D
