General Information
Overview
EN 4017:2001 is a European standard developed by CEN that specifies the characteristics of 90° elbows used in aerospace pipe couplings with an 8°30' angle, manufactured from titanium alloy. This standard is part of the aerospace series standards and targets components functioning under high pressure and varied temperature conditions typical for aerospace fluid systems.
Key specifications include:
- Nominal pressure: up to 28,000 kPa
- Temperature range: -55°C to 135°C
- Material: Titanium alloy as per aerospace-grade requirements
- Applicability: Aerospace fluid systems requiring durable, high-performance pipe couplings and elbows
This standard helps ensure compatibility, safety, and reliability in critical aerospace piping assemblies.
Key Topics
Design and Dimensions
The standard defines dimensional requirements, mass limits, and configuration parameters for 90° titanium alloy elbows with 8°30' pipe couplings. Dimensions conform to detailed figures and tables, ensuring consistency across manufacturers. Pipe nominal outside diameters and threaded connections (MJ series) follow ISO 5855-3 standards for aerospace applications.Material and Surface Quality
Titanium alloy use per EN 3311, EN 3312, EN 3314, or EN 3315 ensures lightweight yet robust performance. Surface treatments include abrasive blasting with non-metallic grit, followed by lubricant coating according to EN 2491. Internal surface finish demands a radius of 0.3 to 1.0 mm and a surface roughness of 0.8 μm to optimize flow and reduce wear.Marking and Identification
Marking requirements comply with EN 2424 style A, facilitating traceability and quality control across aerospace manufacturing and maintenance processes.Technical Compliance
Elbows must meet the technical specifications outlined in EN 3275, type II, incorporating dynamic seals and thread end configurations to withstand operational stresses up to the 28,000 kPa pressure rating.
Applications
EN 4017:2001 elbows are critical components in aerospace fluid systems, where reliable pipe connections under high pressures and temperature fluctuations are essential. Applications include:
- Aircraft hydraulic and fuel systems
- Pressurized fluid transport in aerospace vehicles
- High-performance aerospace mechanical assemblies requiring corrosion-resistant and lightweight pipe fittings
The titanium alloy construction provides significant advantages in strength-to-weight ratio and corrosion resistance, ideal for aerospace environments exposed to extreme conditions.
