Full title and description

ISO 10433:1994 — Petroleum and natural gas industries — Drilling and production equipment — Specification for wellhead surface safety valves and underwater safety valves for offshore service. The standard adopts and modifies the requirements of API Specification 14D (ninth edition, 1994) to provide international requirements for surface and subsea safety valves used on offshore wellheads and associated equipment.

Abstract

This International Standard specifies requirements for wellhead surface safety valves and underwater (subsea) safety valves intended for offshore service. It adopts API Spec 14D (9th edition, 1994) with editorial and technical modifications to make the document suitable for international application, covering design, materials, performance and testing requirements.

Scope

ISO 10433:1994 applied to the specification of wellhead surface safety valves and underwater safety valves for offshore service. It covered functional and performance requirements, material selection, pressure ratings, testing (including hydrostatic and operational tests), marking, and documentation required to ensure safe and reliable isolation of wells in offshore drilling and production operations. The standard incorporated API Spec 14D requirements with specified international modifications.

Key topics and requirements

• Adoption and modification of API Specification 14D (9th edition, 1994) for international use.
• Design and construction requirements for surface and subsea (underwater) safety valves used on wellheads.
• Material and corrosion resistance considerations for offshore service environments.
• Pressure and temperature ratings, including test pressures and minimum performance criteria.
• Factory and acceptance testing procedures (hydrostatic, functional/operational tests, inspection and marking).
• Documentation, traceability and marking requirements for certification and in-service identification.

Typical use and users

Used by oil and gas operators, drilling and production equipment manufacturers, subsea equipment suppliers, inspection and testing organisations, and engineering firms involved in offshore wellhead and christmas tree equipment. The standard supported procurement specifications, design verification, testing protocols, and regulatory compliance for safety-critical valve equipment in offshore installations.

Related standards

ISO 10433:1994 has been superseded and consolidated into later standards addressing wellhead and christmas tree equipment, notably ISO 10423 (published 2001 and later revisions). ISO/TC 67 technical committee publications and API Spec 14D are closely related reference documents. Users should consult the later ISO 10423 series and current API and ISO publications for up-to-date requirements.

FAQ

Q: What is this standard?

A: ISO 10433:1994 is an international standard that specified requirements for wellhead surface safety valves and underwater safety valves for offshore service, adopting API Spec 14D (9th edition, 1994) with international modifications.

Q: What does it cover?

A: It covers design, materials, performance, pressure/temperature ratings, testing (hydrostatic and operational), marking, documentation and acceptance criteria for safety valves used on offshore wellheads and subsea installations.

Q: Who typically uses it?

A: Oil and gas operators, manufacturers of wellhead and subsea valves, engineering and inspection firms, procurement specialists, and regulatory bodies concerned with offshore production safety.

Q: Is it current or superseded?

A: ISO 10433:1994 has been withdrawn. Its content was consolidated into later standards addressing wellhead and christmas tree equipment (for example ISO 10423 series). Users should refer to the later ISO 10423 publications and current API specifications for the up-to-date requirements.

Q: Is it part of a series?

A: Yes — it relates to a family of standards for drilling and production equipment under ISO/TC 67 (Drilling and production equipment), and specifically to the set of standards covering wellhead and christmas tree equipment (ISO 10419, ISO 10423 series and related documents).

Q: What are the key keywords?

A: Wellhead, surface safety valve, underwater/subsea safety valve, offshore service, API 14D, well isolation, christmas tree, subsea equipment.
