Overview
ISO 10432:2004 - Petroleum and natural gas industries - Downhole equipment - Subsurface safety valve equipment - defines the minimum acceptable requirements for subsurface safety valves (SSSVs) used in oil and gas wells. The standard applies to SSSVs and all components whose tolerances or clearances affect performance or interchangeability. It covers manufacture, repair operations, functional and validation testing, interface connections to flow-control equipment, and requirements for supplier/manufacturer quality and traceability. Redress activities and connections to the well conduit are excluded.
Key topics and technical requirements
- Functional specification: minimum functional characteristics, well and operational parameters, environmental compatibility and compatibility with related well equipment.
- Technical specification: design criteria, technical characteristics, design verification and validation, and management of design changes.
- Testing requirements: detailed provisions for functional testing, validation testing and test-agency competence (normative annexes address test agency, validation and functional test requirements).
- Manufacturing and supplier obligations: raw material controls, heat-treating qualifications, component traceability, special-process controls, quality control, product identification and documentation.
- Inspection and nondestructive testing: references to accepted NDT methods and laboratory competence standards for SSSV components.
- Storage and transport: handling, storage and preparation for shipment to preserve valve integrity.
- Annexes: include mandatory/optional test criteria, operating envelope guidance, leakage options, and required data/schematics for documentation.
Practical applications and users
ISO 10432 is used to ensure safe, reliable downhole emergency shut-off capability and to standardize SSSV design, manufacture and testing across the petroleum and natural gas industry. Typical users:
- Oil & gas operators and production engineers specifying SSSVs for wells
- Valve manufacturers and suppliers seeking conformity with international requirements
- Procurement and quality assurance teams evaluating vendor documentation and traceability
- Test laboratories and inspection agencies performing validation and functional testing
- Service companies involved in SSSV repair and maintenance (repair operations covered; redress excluded)
Practical benefits include improved interchangeability, documented design verification/validation, consistent functional test protocols, and clearer supplier/manufacturer responsibilities.
Related standards
ISO 10432 cross-references and aligns with other industry documents such as:
- ISO 10417 (SSSV systems design, installation and redress)
- ISO 16070 (lock mandrels and landing nipples)
- ISO 15156 (materials in H2S environments)
- API Spec 14A and relevant ASME/ASTM standards for materials, testing and NDT
- ISO/IEC 17025 for test laboratory competence
