Описание (английский):

Lays down the specification covering the design and rating. Specifies the requirements for the dimensional characteristics, chemical and mechanical properties and gauging practice. Requirements are specified in the sixteenth edition of API Specification 11E (Spec 11E), October 1989, which is adopted as ISO 10431. For the purposes of international standardization, modifications have been made that are outlined.

Overview

ISO 10431:1993 - "Petroleum and natural gas industries - Pumping units - Specification" adopts API Specification 11E (16th edition, 1989) (with Supplement 1, 1991) as an international standard for the design and rating of beam-type pumping units used in the petroleum and natural‑gas industries. The standard defines requirements for dimensional characteristics, mechanical properties, gauging practice and rating methods, and specifies conversion of English units to SI in accordance with ISO 31. ISO 10431 includes modifications for international application and notes that Appendix G (API monogram use) is informational only.

Key topics and requirements

Scope and applicability

Covers design and rating of pumping‑unit structures, gear and chain reducers, beam and crank counterbalances.
Does not cover chemical properties of materials or the operational use of equipment; engineering judgment remains necessary.

Design and rating methods

Standardizes rating procedures for polished‑rod capacity and gives allowable working stresses for structural members (walking beams, saddles, etc.).
Provides a walking‑beam rating formula and defines critical dimensions (A, C, lf) and section limitations (no holes/welds in tension flange critical zone).

Dimensional and conversion practice

Requires unit conversions per ISO 31 (Parts 1 and 3). Examples included in the text:
- 1 in = 25.4 mm (exact)
- 1 ft = 0.3048 m (exact)
- 1 lb = 0.45359237 kg (exact)
- 1 psi = 6894.76 Pa
- 1 in^3 = 16.387064 × 10^-3 dm^3

Appendices and supplementary guidance

Approved data forms (Appendix A).
Recommended practices for calculation/application of torque factors for various lever geometries and counterbalances (Appendices B–F).
Appendix F: torque ratings for gear reducers.
Appendix G: API monogram guidance (informational only).

Applications and users

ISO 10431 is intended for:

Manufacturers of beam‑type pumping units and component suppliers (reducers, counterbalances, beams).

Design and mechanical engineers working on rod‑pump surface equipment who need standardized rating and dimensional guidance.

Procurement and quality inspectors specifying product acceptance criteria and gauging practice.

Oilfield service companies evaluating retrofit, repair or replacement of surface pumping equipment.

Use cases:

Specifying compliant pumping‑unit structures for well lifting capacity.

Determining allowable stresses and ratings for walking beams and reducers.

Calculating torque factors and selecting appropriate gear or chain reducers.
