Overview

EN ISO 27627:2014 - "Petroleum and natural gas industries - Aluminium alloy drill pipe thread connection gauging (ISO 27627:2014)" - defines gauging and verification requirements for aluminium alloy drill pipe threaded connections manufactured to ISO 15546. The standard covers technical delivery conditions, manufacturing, material and dimensional configuration, inspection and calibration procedures specifically for taper buttress threads (right and left) and adjoining tapered stabilizing shoulders on aluminium drill pipes and mating steel tool joints.

Key topics and technical requirements

• Scope and normative reference: Applies to aluminium alloy drill pipe made per ISO 15546; ISO 15546 is normatively referenced.
• Gauging procedures: Specifies how to gauge taper buttress threads and adjoining tapered stabilizing shoulders (bores) to verify conformance.
• Types of gauges: Defines working and master gauge types - e.g., screw plug (R), plain plug (G, G‑S), screw ring (R‑P, R‑N), and master gauges (K‑G‑R, K‑G‑G, K‑G‑G‑S).
• Thread profile, dimensions and tolerances: Includes thread form, basic dimensions, pitch definitions and limit deviations (document contains figures and tables with TT thread sizes and corresponding dimensions).
• Metrology concepts: Introduces terms such as gauge plane, reference plane, pitch, plain plug/ring, screw plug/ring and stabilizing shoulder.
• Manufacturing and technical requirements for gauges: Requirements for gauge manufacture, marking, packing, transport and storage to maintain calibration integrity.
• Verification, inspection and servicing: Procedures for in‑service gauging, calibration of master and working gauges and servicing requirements (sections on gauging of threaded connections and servicing of gauges).

Practical applications and users

Who uses EN ISO 27627:2014:

• Drill pipe manufacturers producing aluminium alloy drill pipe to ensure thread and shoulder conformity.
• Gauge manufacturers and calibration labs that produce and certify working and master gauges.
• Quality control and inspection teams in drilling equipment suppliers and operators performing acceptance testing and periodic inspection.
• Tool joint and connection designers verifying interchangeability and fatigue‑resistant joint assembly.
• Third‑party inspection bodies and procurement/specification engineers responsible for compliance and traceability.

Practical uses:

• Acceptance gauging of new aluminium drill pipe and mating tool joints.
• Routine maintenance checks and calibration of gauging sets.
• Ensuring interchangeability and correct fit-up to reduce thread damage and improve fatigue life thanks to correct stabilizing shoulder verification.

Related standards

• ISO 15546 - Aluminium alloy drill pipe (normative reference for material and manufacturing requirements).

Introduction
Users of this International Standard need to be aware that further or differing requirements could be
needed for individual applications. This International Standard is not intended to inhibit a manufacturer
from offering, or the purchaser from accepting, alternative equipment or engineering solutions for
the individual application. This is particularly applicable where there is innovative or developing
technology. Where an alternative is offered, the manufacturer will need to identify any variations from
this International Standard and provide details.
This International Standard includes requirements of various natures. These are identified by the use
of certain verbal forms:
— “shall” is used to indicate that a provision is mandatory;
— “should” is used to indicate that a provision is not mandatory, but recommended as good practice;
— “may” is used to indicate that a provision is optional.
