Full title and description
JIS F 7101:2002 — Shipbuilding — Pipes of machinery — Standard velocity of flow. This Japanese Industrial Standard specifies recommended/standard flow velocities and related guidance for pipes used in shipbuilding machinery and onboard piping systems to ensure hydraulic performance, prevent erosion and noise, and support safe piping design and operation.
Abstract
JIS F 7101:2002 provides recommended limits and practices for flow velocity in machinery pipes used in shipbuilding. It defines terminology, measurement/reporting practices and recommended velocity ranges for different applications and fluids commonly encountered in marine machinery systems. The standard is intended to guide designers, shipbuilders and maintenance personnel in selecting appropriate velocities to minimise wear, vibration and operational issues.

- Publisher: Japanese Standards Association (JSA).
- ICS / categories: 47.020.30 — Piping systems (shipbuilding piping).
- Edition / version: JIS F 7101:2002 (2002 edition; revises/succeeds the 1993 edition).
- Number of pages: 18 pages (approx.).
Scope
This standard applies to pipes of machinery in shipbuilding contexts and gives recommended standard velocities for liquids and gases in those pipes. It covers definitions, general principles for choosing velocity limits, measurement and reporting conventions, plus guidance intended for system design, retrofits and inspection planning. It does not replace material- or application-specific statutory requirements but complements them by providing commonly accepted velocity guidance for marine piping systems.
Key topics and requirements
- Definitions and terminology for pipes of machinery and flow-velocity concepts.
- Recommended standard velocities (velocity ranges) for typical fluids and services found in ship machinery piping.
- Design guidance to minimise erosion, noise, vibration and pressure loss associated with excessive flow velocity.
- Measurement and test/reporting procedures for flow velocity in piping systems (how to record and report results).
- Requirements for documentation and design justification when deviating from recommended velocities.
Typical use and users
Primarily used by shipbuilders, naval architects, marine engineers, piping designers and classification society engineers. Also useful to ship operators, maintenance teams, equipment manufacturers and consultants involved in marine piping system design, specification, inspection and retrofit projects.
Related standards
Often used alongside other JIS standards related to piping materials and dimensions (for example standards for copper and alloy pipes) and shipbuilding piping design rules. The 2002 edition is recorded as superseding the earlier 1993 edition and is referenced by other JIS documents dealing with piping and tube standards.
