API Spec 5DP-2020 PDF

Full title and description

API SPEC 5DP — Drill Pipe, Second Edition (2020). This specification defines technical delivery conditions for steel drill pipe with upset pipe-body ends and weld-on tool joints for drilling and production operations in the petroleum and natural gas industries, including requirements for multiple product specification levels (PSL‑1, PSL‑2 and PSL‑3) and coverage of several drill‑pipe grades.

Abstract

API Spec 5DP:2020 establishes dimensional, material, manufacturing, inspection and testing requirements for steel drill pipe used in oil and gas drilling and production. The edition is the U.S. national adoption of ISO 11961 and includes the API Monogram Annex; it provides the basis for procurement, quality assurance and traceability of drill‑pipe products for industry and regulators.

Scope

Specifies technical delivery conditions for steel drill‑pipe with upset body ends and weld‑on tool joints used in drilling and production operations for the petroleum and natural gas industries. Covers material grades (including grade E and higher‑strength grades such as X, G and S), applicable PSL levels (PSL‑1, PSL‑2, PSL‑3), manufacturing and dimensional tolerances, tests, inspection and marking requirements. The edition is published as the U.S. national adoption of ISO 11961 and is based on API Spec 5D and API Spec 7.

Key topics and requirements

• Definitions, symbols and ordering information required when placing drill‑pipe orders.
• Material and grade requirements for drill‑pipe body and tool‑joint materials (including common grades E, X, G, S and high‑strength designations).
• Manufacturing dimensions and tolerances for upset pipe body ends and welded tool joints.
• Product Specification Levels (PSL‑1, PSL‑2, PSL‑3) that define progressively stricter quality and test requirements.
• Required mechanical and non‑destructive testing (tensile, yield, hardness, NDT, chemical analysis, upset inspection, etc.).
• Inspection, marking, documentation and traceability (including API Monogram provisions where applicable).
• Acceptance criteria, repair/rework guidance and provisions for non‑standard tool joints or combinations not explicitly covered by ISO/API.

Typical use and users

Used by drill‑pipe manufacturers, API‑licensed fabricators, procurement and quality teams at oil & gas operators and service companies, inspection and testing laboratories, third‑party certifiers, and regulatory or standards compliance groups. Also referenced by engineering and design personnel specifying drill‑string components and by asset integrity and maintenance teams responsible for selection, acceptance and re‑certification of drill pipe.

Related standards

Closely related to and based on API Spec 5D (tubing and casing/drill‑pipe family), API Spec 7 (threaded connections and tool joints), and ISO 11961 (Steel drill pipe — the international counterpart). The standard also ties into general API Monogram and APIQR program requirements where applicable.

FAQ

Q: What is this standard?

A: API Spec 5DP:2020 is the API specification that sets out technical delivery conditions, material and manufacturing requirements, testing and inspection criteria for steel drill pipe used in petroleum and natural gas drilling and production operations.

Q: What does it cover?

A: It covers drill‑pipe grades, upset body and weld‑on tool‑joint requirements, dimensional tolerances, testing (mechanical and NDT), marking and documentation, and defines three product specification levels (PSL‑1, PSL‑2, PSL‑3) with increasing levels of requirement. It is published as the U.S. national adoption of ISO 11961 and references API Spec 5D and API Spec 7 for related requirements.

Q: Who typically uses it?

A: Manufacturers of drill pipe, oil & gas operators and drilling contractors, procurement and QA/QC teams, inspection bodies, and anyone specifying or certifying drill‑string components for upstream operations.

Q: Is it current or superseded?

A: The 2nd edition (2020) is the current edition; API has published errata and addenda items after initial release (errata/addendum notices and updates have been issued through 2025 in API publications). Users should confirm whether any recent errata or addenda apply to the copies they use.

Q: Is it part of a series?

A: Yes — API Spec 5DP sits within the API family of drilling and tubular standards (notably API Spec 5D and API Spec 7) and aligns with the international ISO 11961 standard for steel drill pipe.

Q: What are the key keywords?

A: Drill pipe, API 5DP, PSL, tool joint, upset end, steel drill pipe, ISO 11961, API Monogram, testing, inspection.
