Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15546 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries.
This third edition cancels and replaces the second edition (ISO 15546:2007), which has been technically
revised.

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 being 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 nature. 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.

Petroleum and natural gas industries — Aluminium alloy drill
pipe
1 Scope
This International Standard specifies the technical delivery conditions, manufacturing process, material
requirements, configuration and dimensions, and verification and inspection procedures for aluminium alloy
drill pipes with or without attached steel tool joints, for use in drilling and production operations in the
petroleum and natural gas industries.
A typical drill pipe configuration is provided, showing main elements and lengths (see Figures 1 to 4). The
main dimensions and masses of the grades of drill pipe are given in both SI units and USC units
(see Annex A).
This International Standard does not consider performance properties.
NOTE 1 Reference can be made to ISO 10424-2 and ISO 27627 for the detailed requirements for the threading of drill
pipe tool joints.
NOTE 2 Reference can be made to ISO 20312 for the performance properties of the drill pipe.
NOTE 3 Reference can be made to ISO 27627 for the “pipe body-tool joint” thread connection gauging.
2 Conformance
In this International Standard, data are expressed in both the International System (SI) of units and the United
States Customary (USC) system of units.
Tables for data expressed in SI units are given in the body of this International Standard, whilst those
expressed in USC units are given in Annex A. All figures in the body of this International Standard express
data in both SI and USC units (the latter given in brackets), with the exception of Figure 11, which is
reproduced as Figure A.1 using USC units. In the text, data in SI units are followed by data in USC units in
brackets.
For a specific order item, it is intended that only one system of units be used, without combining data
expressed in the other system.
Products manufactured to specifications expressed in either of these unit systems shall be considered
equivalent and totally interchangeable. Consequently, compliance with the requirements of this International
Standard as expressed in one system provides compliance with requirements expressed in the other system.
For data expressed in the SI system, a comma is used as the decimal separator and a space as the
thousands separator. For data expressed in the USC system, a dot (on the line) is used as the decimal
separator and a space as the thousands separator.
NOTE The procedures used to convert from SI units to USC units are given in Annex E.
