Aerospace series - Pipe couplings, 60°, spherical, in titanium alloy TI-P64001 - Straight unions, threaded
General Information
Overview
EN 3853:2002 is a European standard developed by CEN that specifies the characteristics of threaded straight unions for aerospace pipe couplings. These couplings feature a 60° spherical design and are manufactured from the titanium alloy TI-P64001, which is well-suited to aerospace applications due to its strength-to-weight ratio and corrosion resistance. This standard is part of the aerospace series focusing on fluid system components, ensuring consistent performance and reliability in critical aerospace environments.
The standard defines the configuration, dimensions, tolerances, and materials used for these pipe coupling unions, providing clear quality assurance and marking requirements. It also references related standards for assembly and port connections, emphasizing the importance of compatibility and precision in manufacturing.
Key Topics
Scope and Purpose
EN 3853:2002 applies specifically to threaded straight unions for pipe couplings that have a 60° spherical seating surface, made from titanium alloy TI-P64001. These components are designed primarily for aerospace fluid systems.Configuration and Dimensions
The standard details exact dimensions, tolerances, and masses for each size of straight unions, referenced in millimeters. Dimensions are presented before lubrication with allowances for precise fits and assembly.Material Requirements
The titanium alloy TI-P64001 is specified for its optimal aerospace performance characteristics, complying with EN 2530. Surface coating requirements employ molybdenum disulphide dry lubricants per EN 2491 to enhance durability and reduce friction.Marking and Identification
Components must be clearly marked in accordance with EN 2424 to ensure traceability, identification, and compliance. This includes standardized labeling styles and batch coding.Quality Assurance
Manufacturers must adhere to quality system approvals outlined in EN 2000, guaranteeing product consistency, safety, and compliance with aerospace standards.Normative References
The standard incorporates other relevant standards such as ISO 5855-3 for thread limits, ISO 286-2 for tolerance grades, and EN 4051/TR 4052 regarding assembly recommendations and port connections.
Applications
EN 3853:2002 establishes critical requirements for straight unions used in aerospace fluid systems, including fuel, hydraulic, and pneumatic lines. The use of titanium alloy TI-P64001 provides weight savings without sacrificing strength, essential for aircraft and spacecraft performance and safety.
Typical applications include:
