API 20E A193 B7 Stud Bolt and 2H Nut
Product Description
API 20E BSL 1 Bolting, API 20E BSL 2 Bolting, API 20E BSL 3 Bolting, API 20F BSL 2 Bolting, API 20F BSL 3 Bolting
API 20E Bolt has, by virtue of its contents of tungsten, chromium, molybdenum, and controlled iron. API 20E standard specifies requirements for the qualification, production and documentation of Alloy and Carbon Steel Bolting for Use in the Petroleum and Natural Gas Industries. The API 20E 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 consequence of bolting failure.
