ISO 10428:1993

Petroleum and natural gas industries - Sucker rods (pony rods, polished rods, couplings and sub-couplings) - Specification

Specifies the requirements for the dimensional characteristics, chemical and mechanical properties and gauging practice. Requirements are specified in the twenty-forth edition of API Specification 11B (Spec 11B), October 1990, which is adopted as ISO 10428. For the purposes of international standardization, modifications have been made that are outlined.

Overview

ISO 10428:1993 - "Petroleum and natural gas industries - Sucker rods (pony rods, polished rods, couplings and sub-couplings) - Specification" adopts API Specification 11B (24th Edition, 1990) with specific modifications for international use. The standard sets requirements for dimensional characteristics, chemical and mechanical properties, and gauging practice for sucker rods and associated components used in petroleum and natural gas well pumping systems. Certain API-specific provisions (for example, the API monogram appendix) are not part of the ISO standard; several test and sampling references are aligned to ISO practice.

Key topics and technical requirements

• Scope and content: Covers one-piece and three-piece sucker rods, pony rods, polished rods, couplings and sub-couplings, polished-rod liners, stuffing boxes and pumping tees, marking, packaging and inspection procedures.
• Materials and grades: Defines chemical and mechanical property requirements for common rod grades (examples given in the source: Grade K, C and D), including specified tensile strength ranges (e.g., Grade K ~85 000–115 000 psi; Grade C ~90 000–115 000 psi; Grade D ~115 000–140 000 psi) and references to AISI grade families.
• Dimensions and threads: Sizes, lengths and end styles are specified (see Table 3.1 in the standard). Pin/box connections and coupling classes are addressed in separate sections.
• Gauging practice and gauges: Detailed gage specification and gaging practice are provided. The document adopts ISO sampling/inspection references (replacement of MIL‑STD‑105D by ISO 2859‑1) for acceptance inspection.
• Unit conversions and internationalization: Conversion of English units follows ISO conventions (e.g., 1 in = 25.4 mm; 1 ft = 304.8 mm; 1 ft·lbf = 1.355818 N·m).
• Limitations: The gauge certification system specified is not considered an integral part of the ISO standard and is subject to further study for a possible ISO certification scheme. Appendix A (API monogram) and some policy items apply only to the API publication.

Applications and users

ISO 10428 is intended for:

• Manufacturers of sucker rods, couplings and polished rods who need standardized material, dimensional and threading requirements.
• Procurement and quality engineers in the petroleum and natural gas industries specifying rod materials and acceptance criteria.
• Inspection and testing laboratories performing tensile, chemical and gaging verification.
• Standards committees and certification bodies aligning API Spec 11B content with international ISO practice.

Related standards

• API Specification 11B (Spec 11B), 24th Edition - base document adopted by ISO 10428
• ISO 2859‑1 - sampling procedures referenced in place of MIL‑STD‑105D

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be re-
presented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) on all matters of electrotechnical standardization.
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.
International Standard IS0 10428 was prepared by the American Petro-
leum Institute (API) (as Spec 11 B, 24th edition) and was adopted, under
a special “fast-track procedure”, by Technical Committee ISO/TC 67, Ma-
terials, equipment and offshore structures for petroleum and natural gas
industries, in parallel with its approval by the IS0 member bodies.

Introduction
International Standard IS0 10428:1993 reproduces the content of
API Spec 11 B, 24th edition, 1990, and its Supplement 1 (April 1, 1991).
ISO, in endorsing these API documents, recognizes that in certain re-
spects they do not comply with all current IS0 rules on the presentation
and content of an International Standard. Therefore, the relevant technical
body, within lSO/TC 67, will review IS0 10428:1993 and reissue it, when
practicable, in a form complying with these rules.
This standard is not intended to obviate the need for sound engineering
judgement as to when and where this standard should be utilized and
users of this standard should be aware that additional or differing require-
ments may be needed to meet the needs for the particular service in-
tended.
Standards referenced herein may be replaced by other international or
national standards that can be shown to meet or exceed the requirements
of the referenced standards.
Appendix A to the API document shall not be regarded as being part of the
requirements of this standard.

Petroleum and natural gas industries - Sucker rods
(pony rods, polished rods, couplings and
sub-couplings) - Specification
1 Scope
This International Standard specifies the requirements for the dimensional characteristics, chemical and mechan-
ical properties and gauging practice of sucker rods (pony rods, polished rods, couplings and sub-couplings) used
in the petroleum and natural gas industries.
2 Requirements
Requirements are specified in:
“API Specification 11 B (Spec 11 B), Twenty-forth Edition, October 1, 1990
- Specification for Sucker Rods
(Pony Rods, Polished Rods, Couplings and Subcouplings)“,
which is adopted as IS0 10428.
For the purposes of international standardization, however, modifications shall apply to specific clauses and para-
graphs of publication API Spec 11 B. These modifications are outlined below.
Throughout publication API Spec 11 B, the conversion of English units shall be made in accordance with IS0 31.
LENGTH 1 inch (in) = 25,4 mm (exactly)
1 foot (ft) = 304,8 mm or 0,3048 m (exactly)
TORQUE 1 foot-pound force (ftlbf) = 1,355818 N#m
TEMPERATURE The following formula was used to convert degrees Fahrenheit (OF) to degrees
Celsius (“C)
