Full title and description

ISO 10424-1:2004 — Petroleum and natural gas industries — Rotary drilling equipment — Part 1: Rotary drill stem elements. Specifies requirements for key drill-stem components such as kelly valves, kellys, drill stem subs, drill collars and drilling/coring bits.

Abstract

ISO 10424-1:2004 sets out dimensional, material and inspection requirements for rotary drill-stem elements used in petroleum and natural gas drilling operations. It defines the elements covered (upper and lower kelly valves; square and hexagonal kellys; drill stem subs; standard steel and non-magnetic drill collars; drilling and coring bits) and states items to which it is not applicable (for example drill pipe and tool joints, rotary-shouldered connection designs, thread gauging practice and master gauge systems).

Scope

This part of ISO 10424 specifies requirements for rotary drill-stem elements used in petroleum and natural gas industries: upper and lower kelly valves; square and hexagonal kellys; drill stem subs; standard steel and non-magnetic drill collars; drilling and coring bits. It explicitly excludes drill pipe and tool joints, rotary-shouldered connection designs, thread-gauging practice, and master/reference/working gauges.

Key topics and requirements

• Definition and designation of drill-stem element types (kelly valves, kellys, subs, collars, bits).
• Dimensional and threading requirements where applicable, and required material characteristics (including non-magnetic collars).
• Inspection and testing criteria for acceptance and fitness for service.
• Statements of non-applicability (drill pipe, tool joints, rotary-shouldered connection gauging).
• Harmonization / equivalence with other industry documents (adopted/identified equivalents in regional catalogs).

Typical use and users

Used by drilling-equipment manufacturers, drilling contractors, procurement/specification engineers, inspection and certification bodies, and standards committees for design, procurement and quality-control of rotary drill-stem components in oil & gas operations.

Related standards

Closely related to other parts of the ISO 10424 series (for example ISO 10424-2 on threading and gauging of rotary-shouldered connections) and to industry specifications such as API 7-1 where equivalence or alignment has been established. National and regional adoptions exist as EN ISO / BS EN versions.

FAQ

Q: What is this standard?

A: ISO 10424-1:2004 is an International Standard that specifies requirements for rotary drill-stem elements used in petroleum and natural gas drilling operations.

Q: What does it cover?

A: It covers dimensional, material and inspection requirements for components such as upper and lower kelly valves, square and hexagonal kellys, drill stem subs, standard steel and non-magnetic drill collars, and drilling and coring bits; it also lists components/practices to which it does not apply.

Q: Who typically uses it?

A: Equipment manufacturers, drilling contractors, procurement and quality engineers, testing/inspection bodies and standards committees involved in oil & gas drilling equipment specifications and procurement.

Q: Is it current or superseded?

A: ISO 10424-1:2004 has been withdrawn (ISO lifecycle status: Withdrawn). Some national/regional bodies list the withdrawal and related adoption history; one catalog records the withdrawal effective from 4 April 2025. Users should consult their national standards body or ISO for the replacement or current normative references.

Q: Is it part of a series?

A: Yes — ISO 10424 is a multi-part series addressing rotary drilling equipment; Part 1 addresses drill-stem elements and Part 2 addresses threading and gauging of rotary-shouldered thread connections, among other related parts and regional adoptions.

Q: What are the key keywords?

A: Drill stem elements, kelly valve, kelly, drill collar, drill bit, rotary drilling equipment, petroleum and natural gas industries, inspection, dimensional requirements.
