General Information
Overview
EN 4563:2003 is a European standard developed by CEN (European Committee for Standardization) that specifies the characteristics and technical requirements for welded tees used in pipe couplings made from heat-resisting steel. This standard focuses on inch series pipe couplings designed primarily for aerospace applications. It ensures the quality and consistency of pipe coupling tees, which are critical components in aerospace fluid systems and components.
The standard applies to welded tees manufactured for use under nominal pressure Class D per ISO 6771, emphasizing high durability and heat resistance ideal for aerospace environments.
Key Topics
Scope and Purpose
Defines welded tee characteristics for inch series pipe couplings in heat-resisting steel, intended for aerospace use with specific pressure and temperature ratings.Materials and Configuration
The materials conform to related aerospace steel standards such as EN 3363, EN 3468, and EN 3487, ensuring strength and heat resistance suitable for aerospace fluid systems.Dimensions and Tolerances
Detailed dimensional specifications, tolerances, and masses are provided in millimeters, covering multiple nominal diameters and wall thicknesses. These ensure interchangeability and reliability in assembly.Weld End Options
Weld end options are clearly defined, including tees with weld ends on one or both sides, applicable to different manufacturing methods.Marking and Identification
Marking requirements conform to EN 2424, providing traceability and certification for aerospace compliance. Designation codes follow a standardized format incorporating dimensional and weld end information.Technical Specifications
The technical specifications refer to EN 4560, linking to standardized requirements for aerospace pipe coupling components such as pressure ratings and design configurations.
