API20E/20F BSL 1/2/3 Bolting

In critical applications within the oil and gas industry, the integrity and reliability of bolted connections are essential for ensuring safe and efficient operations.

API 20E, developed by the American Petroleum Institute, sets the standard for the specification of alloy and carbon steel bolting materials used in high-pressure and high-temperature service environments. This standard outlines the manufacturing, testing, and documentation requirements necessary to produce high-quality bolting that can withstand the rigorous demands of subsea, offshore, and onshore equipment. By adhering to API 20E and 20F, manufacturers and end-users can ensure consistent performance, enhanced safety, and compliance with industry best practices.

(BSL)Bolting Specification Levels

BOMCO CANSCO guarantees that the products are manufactured and tested under the most extreme conditions. BOMCO CANSCO is able to provide (BSL) Bolting Specification Levels in the three existing levels, which proves our commitment to technology and engineering excellence.

The API 20E/20F specification establishes three bolting specification levels (BSL-1, BSL-2 and BSL-3). These BSLs define ascending levels of technical, quality, and qualification requirements. Increasing levels of severity reflect increased consequences of bolting failure. The highest level of criticality, BSL-3, is expected to be reserved for those applications in which bolting failure is not an acceptable option. A common definition for BSL-3 application is a “critical application; one through which a bolt failure would result in the release of hydrocarbons into the atmosphere.”
