EN 4562:2003 - Aerospace series - Pipe coupling, welded, in heat resisting steel - Reductors - Inch series

Overview

EN 4562:2003 is a CEN/AECMA aerospace standard that specifies the characteristics of welded reductors (reducers) for inch-series pipe couplings manufactured in heat-resisting steel for aerospace fluid systems. It defines configuration, dimensions, tolerances, masses, materials, designation and marking for welded reductors. The standard applies to components rated at Nominal Pressure: Class D (per ISO 6771).

Key topics and requirements

  • Scope and purpose: Standardizes welded reductors used in aerospace pipe coupling systems (inch series) to ensure interchangeability, traceability and safe pressure classification.
  • Configuration, dimensions and tolerances: Detailed dimensional drawings and tabulated data (smallest and biggest nominal diameter on weld end side) provide nominal diameters, wall thickness options and part masses. Dimensions and tolerances are given in millimetres.
  • Dimensional codes and wall thickness: Dimensional codes encode the weld-end and other-side nominal diameters (expressed in 1/16 inches) and tube wall thickness types. The two wall-thickness codes shown are A = 0.711 mm and B = 0.889 mm.
  • Materials: Acceptable materials reference aerospace steel classes per EN 3363, EN 3468 or EN 3487 (heat-resisting steel variants suited to castings, forgings or bars for machining).
  • Weld end detail: Weld ends conform to the referenced weld end configuration (illustrated as C33 in the standard figures).
  • Designation and marking: A standard designation format is given (example: REDUCTOR EN4562 A1012) and marking requirements follow EN 2424 (style A) and the standard’s figures to ensure product identification and traceability.
  • Technical specification: Inspection and testing requirements refer to EN 4560 (technical specification for inch-series pipe couplings).

Applications and users

  • Primary users: aerospace component manufacturers, piping and tubing suppliers, design and stress engineers, quality assurance and procurement teams in the aerospace supply chain.
  • Typical applications: fluid system assemblies on aircraft and aerospace platforms where welded inch-series couplings require heat-resistant steel reductors-for routing hydraulic, fuel or pneumatic lines where different nominal diameters must be joined while meeting Class D pressure and temperature classifications.

Related standards

  • ISO 6771 - Pressure and temperature classifications for aerospace fluid systems (defines Class D).
  • EN 2424 - Marking of aerospace products.
  • EN 3363, EN 3468, EN 3487 - Material specifications for aerospace steels.
  • EN 4549 - Coupling end configuration for heat-resisting steel nickel alloys (inch series).
  • EN 4560 - Technical specification for inch-series pipe couplings.

EN 4562:2003 ensures consistent form-fit-function for welded reductors in aerospace fluid systems, improving compatibility, safety and procurement clarity across suppliers and OEMs.
