Full title and description

ISO 10440-2:2001 — Petroleum and natural gas industries — Rotary-type positive-displacement compressors — Part 2: Packaged air compressors (oil-free). This part of ISO 10440 specifies minimum design, construction, testing and vendor‑data requirements for packaged oil‑free rotary compressors (helical, spiral and straight‑lobe types) intended for refinery and process services up to 0.20 MPa, and intended for continuous duty on process units.

Abstract

This standard covers minimum requirements for helical, spiral and straight‑lobe oil‑free rotary compressors used for applications up to 0.20 MPa (2 bar) in refinery and petroleum/gas process services. It applies to air and other inert gases for continuous duty on process units and excludes oil‑injected rotary compressors. The document defines required technical data, design features, accessories, inspection and testing, and vendor data/data sheets to be provided with proposals and orders.

Scope

ISO 10440-2:2001 establishes the minimum technical requirements for packaged, oil‑free rotary positive‑displacement compressors used in the petroleum and natural gas industries at pressures up to 0.20 MPa. The scope covers mechanical design elements (pressure casing, rotating elements, bearings, seals), package accessories (drivers, couplings, guards, controls, instrumentation), piping and mounting, inspection and testing procedures, and vendor data including data sheets to be supplied with quotations and orders. The standard explicitly excludes oil‑injected rotary compressors.

Key topics and requirements

• Applicability to helical, spiral and straight‑lobe oil‑free rotary compressors for process/refinery services.
• Maximum nominal service pressure limit up to 0.20 MPa (2 bar) as specified in the standard.
• Mandatory design and construction items: pressure casing requirements, casing connections and penetrations, external loads and moments.
• Requirements for rotating elements, seals, rotordynamics and bearing arrangements (bearing housings, lubrication where applicable).
• Specification of accessories: drivers, couplings, guards, mounting plates, and package controls/instrumentation.
• Material selection, nameplate information and marking requirements for vendor identification and traceability.
• Inspection, testing and preparation-for‑shipment procedures, including acceptance checks and performance test expectations where applicable.
• Vendor documentation and data sheets (Annex A normative data sheet format and purchaser decision points identified throughout the clauses).

Typical use and users

Used by compressor manufacturers, package suppliers, procurement and contracts engineers, process and mechanical engineers in refineries, petrochemical plants and gas processing facilities. Also used by operations and maintenance teams for specifying replacement packages, preparing purchase orders, and defining factory and site acceptance tests.

Related standards

Closely related documents include other parts of the ISO 10440 series (for example ISO 10440-1 for process compressors — later editions exist), ISO standards covering compressor acceptance and performance testing (for example ISO 1217), and various industry guidance and API standards that address compressor equipment selection, testing and installation. Users commonly cross‑reference ISO 10440‑1 (process compressors) and ISO 1217 (displacement compressor acceptance tests) when specifying packed compressor equipment for petroleum and petrochemical applications.
