Overview
ISO 14723:2025 is an international standard that defines the requirements for subsea pipeline valves used in the oil and gas industries, including lower carbon energy sectors. This standard covers the design, manufacturing, quality control, assembly, testing, and documentation of various valve types-ball, check, gate, plug, and axial on–off valves-specifically intended for subsea pipeline systems. It applies to ASME Class 150, 300, 600, 900, 1500, and 2500 valves, ensuring their suitability for the demanding conditions found in subsea petroleum and natural gas transportation.
This standard supplements API 6DSS (3rd edition, 2017) and its addenda, incorporating additional requirements to address subsea-specific applications. It is an essential reference for manufacturers, engineers, and operators involved in the pipeline transportation sector to guarantee valve performance, reliability, and safety under subsea conditions.
