ISO 14723-2001 rus PDF

Full title and description

Ст ISO 14723-2001 rus — Petroleum and natural gas industries — Pipeline transportation systems — Subsea pipeline valves. This entry refers to the ISO international standard originally published in December 2001 covering design, manufacture, testing and documentation requirements for valves intended for subsea pipeline applications; "rus" indicates a Russian-language edition or translation of the 2001 text where available.

Abstract

Specifies minimum requirements and gives recommendations for design, manufacture, testing and documentation of ball, check, gate and plug valves for subsea applications in offshore pipeline systems that meet the requirements of ISO 13623. The standard excludes valves for pressure ratings exceeding PN 420 (Class 2500). Annex A provides purchaser guidance for valve selection and specification; Annex B provides a checklist of information to be supplied when ordering valves.

Key bibliographic and lifecycle details as published by ISO.

Scope

Covers the requirements and recommendations for subsea pipeline valves (ball, check, gate and plug) used in offshore pipeline transportation systems that conform to ISO 13623. The document addresses design, materials, manufacturing, quality control, testing, marking and documentation requirements relevant to subsea service but does not apply to valves rated above PN 420 (Class 2500). Annexes give purchaser guidance and order-checklist information.

Key topics and requirements

• Design requirements for ball, check, gate and plug valves for subsea service.
• Material selection and corrosion/compatibility considerations for offshore environments.
• Manufacturing and quality-control provisions, including documentation and traceability.
• Type and factory testing (hydrostatic, functional, leakage) appropriate to subsea applications.
• Pressure-rating limits (standard not applicable above PN 420 / Class 2500).
• Guidance for purchaser specification and ordering (Annex A — selection guidance; Annex B — information checklist).

These topics reflect the core technical content and purchaser-focused guidance of the 2001 edition.

Typical use and users

Used historically by valve manufacturers, pipeline and subsea equipment designers, offshore project engineers, procurement teams, inspection and certification bodies, and regulatory/compliance personnel involved in specifying, supplying or verifying subsea pipeline valves. Project teams commonly consulted the standard when defining technical purchase specifications and factory test programs for valves to be installed on subsea pipeline systems.

Related standards

Closely related to ISO 13623 (pipeline systems — design and operation principles) and to API/ASME valve standards used in subsea pipeline practice (the later ISO 14723 editions reference API 6DSS and related API specifications). ISO technical committee: ISO/TC 67/SC 2. The 2001 edition was revised by subsequent ISO 14723 editions (2009) and ultimately updated by ISO 14723:2025.

FAQ

Q: What is this standard?

A: ISO 14723:2001 is an international standard that provided requirements and recommendations for the design, manufacture, testing and documentation of subsea pipeline valves (ball, check, gate, plug). The record "Ст ISO 14723-2001 rus" denotes a Russian-language edition or listing of that 2001 standard.

Q: What does it cover?

A: It covers technical requirements for valve design and construction suitable for subsea pipeline service, factory testing and documentation requirements, and includes annexes to assist purchasers with valve selection and order information. It specifically excludes valves with pressure ratings above PN 420 (Class 2500).

Q: Who typically uses it?

A: Valve manufacturers, offshore pipeline engineers, procurement/specification teams, testing and inspection bodies, and certification authorities involved in subsea pipeline projects historically used this standard as a technical reference when specifying or verifying subsea valves.

Q: Is it current or superseded?

A: The 2001 edition has been withdrawn and superseded by later editions (ISO 14723:2009) and ultimately by ISO 14723:2025. Users should refer to the most recent edition (ISO 14723:2025) for current requirements.

Q: Is it part of a series?

A: Yes — ISO 14723 is part of the ISO suite of standards for pipeline transportation systems under ISO/TC 67 and is intended to be used together with related pipeline and petroleum industry standards such as ISO 13623 and applicable API/ASME valve specifications. Subsequent editions evolved the content and cross-references (see ISO 14723:2009 and ISO 14723:2025).

Q: What are the key keywords?

A: Subsea valves, pipeline valves, ball/check/gate/plug valve, subsea pipeline, offshore valves, valve testing, ISO 13623, PN 420, Class 2500.
