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 20312 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries.

Introduction
The function of this International Standard is to define operating limits of aluminium drill pipes and recommend
design criteria for the drill stem containing such aluminium drill pipes. This International Standard contains
formulas and figures to aid in the design and selection of equipment to meet a specific drilling condition.
In this International Standard, data are expressed in the International System of units (SI).
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,
particularly 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 provisions 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.

4 Properties of ADP and tool joints
4.1 General
Dimensional and mechanical properties of new ADP and tool joints shall be as specified in ISO 15546. The
pipes may be with external or internal upset ends, and with protector thickening. Separate tables of the
chapter include the data on the drill pipe torsional strength, tensile strength, and resistance against internal
and external pressure.
4.2 New pipes and tool joints data
The new pipes and tool joint data properties are given in Tables 1 and 2.
4.3 Buoyant weight
The ADP buoyant weight of different length groups in the fluids of different density could be calculated by
Equation (B.5). The equivalent density of new pipes is given in Tables 1 and 2. For mass calculation purposes,
3
the assumed aluminium alloy density in Tables 1, 2, 5, 6 and 7 is 2 800 kg/m , and the steel density is
3
7 850 kg/m . If alloys of other density are used, a correcting factor shall be applied.
EXAMPLE
Objective: Calculate the weight of 1 m of ADP 147 11; 11,8 m long; with internal upset ends; with protector thickening in
3
drilling mud with gravity 1 200 kg/m .
3
Solution: According to Table 2, the mass of 1 m of this pipe is 21,45 kg, equivalent density is 3 271 kg/m .
The weight in mud will be as follows:
1200
w21,45 9,81 1 133,2 N/m
m
3 271
4.4 Mechanical properties
The mechanical properties of new pipe (tensional yield strength, torsional yield strength, internal yield and
collapse pressure values) are given in Table 3. The properties correspond to the temperature of 20 °C. The
“weak section” for the calculations was assumed to be the aluminium drill pipe body.
The mechanical properties of the premium class pipe are given in Table 4.
The mechanical properties of class 2 pipe are given in Table 5.
The wear classification of ADP is based on 8.3 and Table 12.

ISO/DIS 20312
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.

a
Value is calculated by Equation B.3 in Annex B.
b
Value is calculated by Equation B.4 in Annex B.
4.3 Buoyant weight
The ADP buoyant weight of different length groups in the fluids of different density could be calculated by
Equation B.5 of Annex B. The equivalent density of new pipes is given in Table 1. For mass calculation
3
purposes the assumed aluminium alloy density in Tables 1, 2, 5, 6, and 7 is 2,78 g/cm , and the steel density
3
is 7,85 g/cm . In case the alloys of other density are used a correcting factor shall be applied.
EXAMPLE Objective: Calculate the weight of 1 m of ADP 147 x 11, 12 m long, with internal upsets in drilling mud
3
with specific gravity 1 200 kg/m .
3
Solution: According to the Table 2 the mass of 1m of this pipe is 20,71 kg, equivalent density is 3 298 kg/m .
The weight in mud would be
w = 20,71 × 9,81 × (1 – 1 200/3 298) = 129,2 N/m.

4.4 Mechanical properties
The mechanical properties of new pipes (tensile loads, torque, internal yield and collapse pressure values) are
given in Table 3. The properties correspond to the temperature of 20 °C. The “weak section” for the
calculations was the pipe body. The design of ADP provides the strength of “tool joint” and “tool joint to pipe”
connection 15 % more than at the “weak section” of the pipe.
The mechanical properties of the premium class pipes are given in Table 4.
The mechanical properties of 2 class pipes are given in Table 5.
4.5 ADP with integral tool joint and heavy weight ADP
ISO 15546 does not cover the ADP with the integral tool joint and heavy weight ADP which are manufactured
in the assembled condition with steel tool joints (Figure A.2). Their technical properties are given in Annex A.
ADP with integral rotary shouldered connections are used as technological sets in the intervals where the
danger of drill string sticking exists. Heavy weight ADP are widely used in BHA to ensure smooth stiffness
transition from drill collars to steel drill pipes or as diamagnetic pipes to perform directional survey inside the
drill string when drilling directional or vertical wells.
