ISO 10438-3-2007 PDF

Full title and description

ISO 10438-3:2007 — Petroleum, petrochemical and natural gas industries — Lubrication, shaft-sealing and control-oil systems and auxiliaries — Part 3: General-purpose oil systems. This part specifies requirements for oil systems that supply lubrication oil (but not seal oil) for general-purpose applications serving equipment such as compressors, gears, pumps and drivers; it is intended to be read in conjunction with ISO 10438-1.

Abstract

ISO 10438-3:2007, together with ISO 10438-1, defines technical requirements, typical system schematics and recommended practices for general-purpose lubrication oil systems used in the petroleum, petrochemical and natural gas industries. The standard covers system configuration, components, filtration, reservoirs, pumps, piping, instrumentation and basic testing/commissioning guidance for lubrication-only oil systems.

Scope

ISO 10438-3:2007 specifies requirements for oil systems for general-purpose applications in the petroleum, petrochemical and natural gas industries; these systems supply lubrication oil (not seal oil) and are applicable to equipment such as compressors, gears, pumps and drivers. The part is intended to be used alongside ISO 10438-1 and does not apply to internal combustion engine lubrication systems.

Key topics and requirements

• System classification and intended application (general-purpose lubrication systems only).
• Recommended system schematics and layout principles for reservoirs, pumps and piping.
• Requirements for filtration, contamination control and oil cleanliness practices.
• Guidance for selection and installation of pumps, heat exchangers, strainers and valves.
• Instrumentation and monitoring: pressure, temperature and level controls, alarm and shutdown considerations.
• Commissioning, testing and basic maintenance recommendations.
• Compatibility and material considerations for oil/wetted parts and additives.

Typical use and users

Used by petroleum, petrochemical and natural gas facilities, equipment designers, rotating-equipment engineers, maintenance teams, OEMs and consultants to specify, purchase, design and maintain lubrication oil systems for compressors, pumps, gearboxes and drivers in industrial installations.

Related standards

ISO 10438-1 (general requirements) should be used together with this part. ISO 10438 is associated with industry guidance for lubrication and oil systems and is often cross-referenced alongside industry/API documents for rotating equipment systems (for example, API 614-related guidance in industry practice).

FAQ

Q: What is this standard?

A: ISO 10438-3:2007 is Part 3 of the ISO 10438 series, giving requirements and guidance for general-purpose lubrication oil systems used in the petroleum, petrochemical and natural gas industries.

Q: What does it cover?

A: It covers system definitions, typical schematics, component selection and installation guidance (reservoirs, pumps, filters, piping), instrumentation and basic commissioning/maintenance recommendations for lubrication-only oil systems. It does not cover seal oil systems or internal combustion engine lubrication.

Q: Who typically uses it?

A: Equipment designers, rotating-equipment engineers, plant maintenance teams, OEMs and procurement/specification writers in the petroleum, petrochemical and natural gas sectors.

Q: Is it current or superseded?

A: Edition 2 (2007) is the published version. ISO records show this edition was reviewed and confirmed in ISO systematic reviews (most recently confirmed in 2020), and it remains the current published edition as of the latest ISO metadata. Users should check ISO or their national standards body for any newer revisions or amendments before relying on the standard for final procurement or design.

Q: Is it part of a series?

A: Yes — ISO 10438 is a multipart standard. Part 1 contains general requirements; Part 3 addresses general-purpose oil systems. Other parts of ISO 10438 address special-purpose systems such as shaft-sealing, self-acting gas seals and control-oil systems.

Q: What are the key keywords?

A: Lubrication oil, oil system, filtration, reservoir, pump, instrumentation, petroleum industry, ISO 10438-3, general-purpose.
