Full title and description

ISO 10423:2022 — Petroleum and natural gas industries — Drilling and production equipment — Wellhead and tree equipment. This International Standard specifies requirements and gives recommendations for the performance, dimensional and functional interchangeability, design, materials, testing, inspection, welding, marking, handling, storing, shipment and purchasing of wellhead and tree equipment for use in the petroleum and natural gas industries.

Abstract

ISO 10423:2022 provides normative requirements and informative guidance to ensure safe, dimensionally and functionally interchangeable wellhead and tree equipment. It clarifies applicability (manufacture and purchase) and explicitly excludes field use/field testing and most field repair (except weld repair in manufacturing). The document also acts as a supplement to API Spec 6A (21st edition) where API requirements apply except as modified by ISO 10423:2022.

General information

• ICS / categories: 75.180.10 (Exploratory, drilling and extraction equipment).

Scope

Applies to the manufacture, testing and purchasing of wellhead and tree equipment used in petroleum and natural gas production and drilling operations. Excludes field use and field testing and excludes repair except for weld repair carried out as part of manufacturing. It does not apply to running/installation tools and many service tools. The 2022 edition is intended to align with and supplement API Spec 6A requirements where noted.

Key topics and requirements

• Performance requirements and product specification guidance for wellhead and tree components (valves, connectors, casing/tubing hangers, chokes, fittings, actuators, etc.).
• Dimensional and functional interchangeability to support safe replacement and compatibility between manufacturers.
• Design and materials criteria, including material classes and service conditions (pressure, temperature, well-bore constituents).
• Testing, inspection and welding requirements; marking, handling, storage and shipment provisions.
• Purchasing, repair and remanufacture considerations with explicit exclusions for most field repairs.
• Supplementary relationship to API Spec 6A (21st edition) — API requirements apply where not superseded by ISO 10423:2022 exceptions.

Typical use and users

Used by oil and gas operators, wellhead and tree equipment manufacturers, procurement teams, third‑party inspection and certification bodies, engineering and design offices, and maintenance/asset integrity groups involved in specification, purchase, manufacture, testing and acceptance of wellhead and tree equipment. It is referenced in contractual specifications and purchase orders for production and drilling equipment.

Related standards

Primary related standard: API Spec 6A (wellhead and christmas tree equipment), which ISO 10423:2022 explicitly supplements. Other related industry standards are often cross‑referenced in national adoptions and technical committees for well design, pressure equipment and materials (see ISO/TC 67 suite of petroleum and natural gas standards and regional EN adoptions).
