Overview
EN 4167:2004 is a European standard established by CEN for aerospace applications, specifying the requirements for inner clips-three-part, spring tension clips made from heat-resisting steel FE-PA2601 (A286). Designed to operate reliably at temperatures up to 260 °C, these inner clips are critical components in aerospace fluid systems and hydraulic installations. EN 4167:2004 ensures uniformity in design, materials, dimensions, and quality, supporting interoperability with complementary parts defined in EN 4166 and EN 4168.
Key Topics
- Scope and Application: Defines characteristics of three-part spring tension inner clips for aerospace use under thermal stress (up to 260 °C).
- Materials: Specifies use of heat-resisting alloy FE-PA2601 (also known as A286), conforming to EN 3638 standards.
- Design and Dimensions: Detailed dimensional tolerances and clip configurations are provided with reference to standard figures and tables ensuring precise fit and function.
- Surface Treatment: Passivation and corrosion protection processes are outlined per EN 2516 to maintain durability in harsh aerospace environments.
- Heat Treatment: Clips undergo precipitation heat treatment post forming to achieve hardness within 260 HV to 345 HV for optimal mechanical performance.
- Marking and Identification: Products must comply with aerospace marking conventions from EN 2424 to ensure traceability and compliance.
- Quality Assurance: Manufacturing processes must align with EN 9100 quality management standards, guaranteeing consistent quality and performance.
Applications
EN 4167:2004 inner clips are used primarily within aerospace fluid and hydraulic systems, where secure and temperature-resistant fastening solutions are vital. Typical applications include:
- Securing tubing and piping assemblies operating under high thermal and mechanical stress.
- Integration with complementary clip components defined in EN 4166 (PTFE bushes) and EN 4168 (outer clips) for complete assembly systems.
- Environments requiring resistance to corrosion and material degradation due to elevated temperatures and aerospace operating conditions.
The spring tension design of these three-part clips allows for reliable, maintenance-friendly installation and retention in critical aerospace assemblies, enhancing safety and operational reliability.
