Full title and description

ISO 10427-1:2024 — Oil and gas industries including lower carbon energy — Equipment for well cementing — Part 1: Casing bow-spring centralizers. This international standard specifies requirements for testing, performance and marking of bow-spring casing centralizers used in oil and gas well construction; it is published as Edition 2 (2024).

Abstract

This document sets out verification and periodic testing procedures, minimum performance criteria and marking requirements for casing bow-spring centralizers. It gives guidance on verification testing for a manufacturer's design, materials and processes, and on periodic testing to confirm consistent product performance. It is explicitly not applicable to rigid/positive centralizers or other types of devices (e.g., cement baskets or tools used for different purposes). The document is published as a supplement to API Spec 10D (7th edition, 2021), whose requirements apply except where ISO 10427-1:2024 specifies otherwise.

Scope

ISO 10427-1:2024 applies to bow-spring casing centralizers intended for use in the construction of oil and natural gas wells. It defines testing procedures (verification and periodic), performance requirements (e.g., restoring and starting forces as appropriate), and marking information required to demonstrate conformity. The standard excludes rigid/positive centralizers and centralizers used for other specialised purposes. It is intended to be used in conjunction with API Spec 10D (7th edition, 2021) where appropriate.

Key topics and requirements

• Verification testing for manufacturer design, materials and manufacturing processes (prototype testing requirements and test-method details).
• Periodic production testing to confirm ongoing product performance and consistency.
• Performance criteria such as starting force and restoring force (values and test arrangements are specified or referenced).
• Marking requirements to identify casing size/fit and relevant test/standard designation.
• Reference and supplement relationship with API Spec 10D (7th edition, 2021) — ISO applies API requirements unless specifically modified.

Typical use and users

Primary users include centralizer and downhole-equipment manufacturers, quality and testing laboratories, drilling and cementing service companies, procurement/specification engineers in oil and gas operators, and conformity assessment bodies. The standard is used to define test procedures during product development, for factory acceptance and for periodic quality surveillance.

Related standards

Key related documents include API Spec 10D (Casing Bow-spring Centralizers, 7th edition, 2021), which ISO 10427-1:2024 supplements; and other parts of the ISO 10427 family (for example ISO 10427-2:2004 covering centralizer placement and stop-collar testing). The 2024 edition replaces earlier ISO 10427-1 editions (notably the 2001 version).

FAQ

Q: What is this standard?

A: ISO 10427-1:2024 is an international standard specifying testing, performance and marking requirements for casing bow-spring centralizers used in oil and gas well cementing.

Q: What does it cover?

A: It covers verification and periodic testing procedures, minimum performance requirements (e.g., starting and restoring forces), and marking information; it excludes rigid centralizers and other devices not intended for the same function. It also operates as a supplement to API Spec 10D (7th ed., 2021).

Q: Who typically uses it?

A: Manufacturers of bow-spring centralizers, testing/QA laboratories, drilling and cementing service providers, procurement/specification engineers within operating companies, and conformity assessors.

Q: Is it current or superseded?

A: ISO 10427-1:2024 is the current published edition (Edition 2, published August 2024) and it replaces the earlier ISO 10427-1:2001 edition.

Q: Is it part of a series?

A: Yes — ISO 10427 is a series addressing equipment for well cementing; Part 1 covers casing bow-spring centralizers and other parts (for example Part 2) address related test methods and placement/stop-collar testing.

Q: What are the key keywords?

A: Casing centralizer, bow-spring centralizer, well cementing, testing, marking, API Spec 10D, oil and gas equipment, verification testing.
