This Standard is based on API Spec 5L, 44th Edition. In the preparation of this document, the technical committee maintained the concept of two basic levels of standard technical requirements for line pipe expressed as two product specification levels (PSL 1 and PSL 2). Level PSL 1 provides a standard quality level for line pipe.
The document announces the publication of the 46th edition of API Specification 5L for line pipe. It provides updates to technical requirements that were reached by consensus within the API subcommittee.
This specification was prepared under a Joint Industry Project 33 (JIP33) “Standardization of Equipment Specifications for Procurement” organized by the International Oil & Gas Producers Association (IOGP) with
