General Information
Overview
SIST EN 3248:2002 is a European standard developed by CEN, specifically addressing aerospace components. It defines the specifications for adaptors with reduced pipe ends and lockrings used in 8°30' pipe couplings made from titanium alloy. These components are designed for installation in a boss and optimized for aerospace fluid systems.
The standard ensures reliability and performance of titanium alloy adaptors under demanding conditions, with a nominal pressure rating up to 28,000 kPa and operational temperature range from -55 °C to 135 °C.
This specification supports high-performance aerospace applications requiring lightweight, corrosion-resistant, and secure pipe couplings.
Key Topics
- Material Specifications: Adaptors are made from titanium alloy compliant with standards EN 3311 and EN 3314, ensuring strength and corrosion resistance needed in aerospace environments.
- Design and Dimensions: Detailed dimensional and configuration requirements are provided, including surface roughness, mass, and thread dimensions. These requirements correspond to other referenced standards such as EN 2602, EN 2603, and EN 2645 for ports, threads, and locking rings.
- Surface Treatments: Adaptors receive lubrication treatment per EN 2491 with precise film thickness (0.005 mm to 0.013 mm) or an anodized finish according to AMS 2488 Type 2 to enhance wear resistance and performance.
- Operational Limits: Suitable for nominal pressures up to 28,000 kPa and temperatures between -55 °C and 135 °C, making them highly reliable for extreme aerospace conditions.
- Marking and Identification: Components must be marked according to EN 2424 to ensure traceability and compliance within aerospace manufacturing and maintenance processes.
- Compatibility: Designed for use with 8°30' pipe couplings, these adaptors integrate with specific pipe and fitting configurations, ensuring secure and efficient fluid system connections.
Applications
SIST EN 3248:2002 adaptors are critical components in aerospace fluid systems, supporting:
- Fuel and hydraulic line connections where high pressure and temperature resistance are mandatory.
- Aerospace structural assemblies requiring lightweight and durable pipe couplings.
- Installation in boss ports within aircraft and spacecraft systems, ensuring secure, leak-free fluid transfer.
- Systems requiring titanium alloy components due to their exceptional strength-to-weight ratio and corrosion resistance.
The standard ensures compatibility and interchangeability within aerospace manufacturing, reducing risks of system failure and maintaining stringent safety standards.
