API SPEC 20B, 2nd Edition, November 2020 - Open Die Shaped Forgings for Use in the Petroleum and Natural Gas Industry

Purpose

This API specification identifies requirements for the forging manufacturer qualification, production, marking, and documentation of open die shaped forgings for use in the petroleum and natural gas industries when referenced by an applicable equipment standard or otherwise specified as a requirement for compliance.

Applicability

This API specification is applicable to equipment used in the oil and natural gas industries where service conditions warrant the use of individually shaped open die forgings, including rolled rings. Examples include pressure containing or load bearing components.

Forged bar, rolled bar, and forgings from which multiple parts are removed are beyond the scope of this specification.

Forging Specification Levels (FSL)

This API specification establishes requirements for four forging specification levels (FSL). These four FSL designations define different levels of forged product technical, quality, and qualification requirements.
