Full title and description

SAE TSC47-025_01 (TSC47-025-01-2018) — Pipelines and Pipe Couplings for Aircraft Fluid Systems (Metric). A technical specification that defines requirements, dimensions, materials, fittings and installation/inspection criteria for pipelines and pipe couplings used in aircraft fluid systems (metric units), excluding aero-engine installations.

Abstract

This SAE Industry Technologies Consortia specification establishes uniform requirements for pipelines, pipe couplings and associated connections to aircraft fluid-system components. It covers metric dimensions, coupling types, end fittings and related workmanship, test and inspection criteria, and tables of standard sizes and tolerances. The document is intended to harmonize design, manufacture and procurement practices for aircraft fluid distribution systems outside of aero-engines.

Scope

Specifies requirements for pipelines, pipe couplings and associated connections to components used in aircraft fluid systems using metric units. The scope excludes pipe systems and fittings intended for aero-engines. Topics include dimensional requirements, material and heat-treatment considerations, coupling and fitting types, assembly and joining methods, applicable tests and inspections, and tabulated standard sizes and tolerances.

Key topics and requirements

• Definitions and scope of applicability for aircraft fluid-system pipelines and couplings.
• Dimensional and tolerance tables (standard tables for metric pipeline sizes and couplings).
• Material and mechanical requirements for pipes, nipples, unions and couplings.
• Design and workmanship requirements for swaged, flared, threaded and other coupling types used in aircraft systems.
• Sealing, adaptor and end-fitting requirements (including guidance on seals and compatible adaptors).
• Assembly, installation, swaging and joining process guidance and acceptance criteria.
• Inspection, testing and quality assurance procedures to verify conformity (including pressure/test methods where applicable).
• Annex notes providing explanatory material relevant to the tabulated requirements.

Typical use and users

Used by aerospace OEMs, aircraft and component designers, system integration engineers, maintenance and repair organizations, procurement specialists and quality/inspection teams. Typical applications include design and selection of pipeline components for hydraulic, pneumatic and other fluid systems on fixed- and rotary-wing aircraft (excluding aero-engines), procurement of compatible couplings and fittings, and preparation of inspection/test criteria for production and maintenance.
