Overview
ISO 3183:2019 - Petroleum and natural gas industries - Steel pipe for pipeline transportation systems - specifies manufacturing and marking requirements for seamless and welded steel line pipe used in petroleum and natural gas pipeline transportation systems. The standard defines two product specification levels, PSL 1 and PSL 2, supplements API Spec 5L (46th edition, 2018), and clarifies exceptions and additional requirements. ISO 3183:2019 is not applicable to cast pipe and includes a normative Annex A for PSL 2 pipe ordered for European onshore natural gas transmission pipelines.
Key topics and technical requirements
- Product scope: Requirements for seamless and welded steel pipes for pipeline transportation systems; two PSLs (PSL 1 and PSL 2).
- Relationship to API Spec 5L: ISO 3183:2019 supplements and references API Spec 5L (46th ed., 2018); API requirements apply except where ISO 3183 specifies exceptions or additions.
- Annex A (normative): Additional provisions specifically for PSL 2 when ordered for European onshore natural gas transmission pipelines (dual-certification considerations with API Spec 5L are referenced).
- Marking and identification: Two marking options are defined - marking as “ISO 3183” or as API 5L with an added “ISO 3183” reference. Required marking elements include manufacturer, standard designation, outside diameter, wall thickness, steel grade, PSL designation, pipe type, purchaser inspector mark, and traceability ID. Hydrostatic test pressures greater than API norms must be indicated (e.g., TESTED 17.5).
- Manufacturing controls & tests: The document references normative test and inspection standards used in conjunction with ISO 3183, such as tensile and impact testing (ISO 6892-1, ISO 148-1), weld bend tests (ISO 5173), and a suite of NDT standards (ISO 10893 series, ISO 9712).
- Quality documentation: Reference to inspection documents and traceability per EN 10204 and EN 10168.
Practical applications and users
ISO 3183:2019 is used by:
- Line pipe manufacturers to meet international production and marking requirements.
- Pipeline engineering and procurement teams specifying PSL 1 or PSL 2 pipe for oil and gas transmission projects.
- Quality, testing and NDT personnel implementing the referenced test methods and inspection regimes.
- Operators and regulators ensuring compliance for onshore and offshore pipeline integrity, with specific attention to European onshore natural gas transmission when Annex A applies.
Typical applications: specification and supply of line pipe for transmission mains, trunk lines and long-distance petroleum and natural gas pipelines where consistent mechanical, chemical and inspection requirements are critical.
