Full title and description

ISO 10422:1993 — Petroleum and natural gas industries — Threading, gauging, and thread inspection of casing, tubing and line pipe threads — Specification. This International Standard specifies dimensional requirements for threads and thread gauges and describes instruments and inspection methods used for casing, tubing and line pipe threads; it adopts API Specification STD 5B (13th edition, 31 May 1988) with ISO-specific modifications.

Abstract

ISO 10422:1993 establishes dimensional requirements, gauging practices, gauge specifications and the instruments and methods for inspection of casing, tubing and line pipe threads used in the petroleum and natural gas industries. The standard is based on API Spec 5B (13th edition) with modifications required for use as an International Standard, and it includes requirements on master gauge certification, gauge transfer/recertification and acceptance criteria for threaded connections.

Scope

This standard applies to the threading, gauging and thread inspection of casing, tubing and line pipe used in petroleum and natural gas operations. It specifies dimensional tolerances for thread forms, the design and specification of thread gauges (master and working gauges), gauging procedures, inspection instruments and methods, and requirements for certification, calibration and transfer or recertification of master gauges. ISO 10422 is intended to ensure interchangeability and reliable make-up performance of threaded tubular connections in drilling, completion and production applications.

Key topics and requirements

• Dimensional requirements for casing, tubing and line pipe threads (forms, limits and tolerances).
• Specifications for master gauges, working gauges and special gauges used for thread inspection.
• Gauging practices and inspection procedures for go/no-go gauging, functional gauging and full dimensional measurement.
• Instrumentation and methods for thread inspection (mechanical gauges, optical and coordinate measuring where applicable).
• Calibration, certification and traceability requirements for master gauges; provisions for transfer and recertification if certificates are unavailable.
• Acceptance criteria and reporting requirements for threaded connections.
• Modifications and deviations from API Specification 5B (13th edition) as required for international application.

Typical use and users

Users include oil & gas operators, tubular goods manufacturers, thread form designers, inspection and quality assurance laboratories, calibration agencies, rig and well completion engineers, procurement specialists, and standards committees. The document was used to specify purchase, inspection and acceptance criteria for threaded tubular products and to guide gauge certification and inspection practice in manufacturing and field inspection.

Related standards

Key related documents and series include API Specification 5B (Specification for Threading, Gauging and Thread Inspection of Casing, Tubing and Line Pipe Threads — basis adopted by ISO 10422), ISO standards from ISO/TC 67/SC 5 covering casing/tubing (for example ISO 11960 on steel pipes for casing/tubing and ISO 10405 on care and use of casing and tubing), and later ISO work items and drafts to revise ISO 10422 (ISO/DIS 10422 drafts). National and industry documents on gauge certification and thread qualification (API guidance and national metrology certification lists) are also commonly used alongside ISO 10422.

FAQ

Q: What is this standard?

A: ISO 10422:1993 is an International Standard specifying threading, gauging and thread inspection requirements for casing, tubing and line pipe used in the petroleum and natural gas industries. It adopts API Spec 5B (13th edition) with ISO modifications.

Q: What does it cover?

A: It covers dimensional requirements for thread forms, specifications for master and working gauges, gauging practice, inspection instruments and methods, calibration and certification of gauges, and acceptance criteria for threaded tubular connections.

Q: Who typically uses it?

A: Tubular goods manufacturers, inspection and calibration laboratories, oil and gas operators, rig and completion engineers, procurement and QA/QC professionals, and standards/technical committees concerned with casing and tubing connections.

Q: Is it current or superseded?

A: ISO 10422:1993 is withdrawn (withdrawal recorded May 25, 2004). It is not an active ISO International Standard; users should refer to current API Specification 5B editions and the suite of ISO/TC 67 standards and any newer ISO revisions or industry specifications that now govern thread gauging and inspection practice.

Q: Is it part of a series?

A: ISO 10422 sits within the body of ISO standards produced by ISO/TC 67 (petroleum and natural gas industries), particularly work by SC 5 on casing, tubing and drill pipe. It is related to other ISO documents addressing tubular products (for example ISO 11960 and ISO 10405) and to API Spec 5B which was the technical basis adopted into this ISO standard.

Q: What are the key keywords?

A: Casing, tubing, line pipe, thread, gauging, thread inspection, API 5B, gauge certification, calibration, petroleum industry.
