General Information
Overview
SIST EN 4019:2002 is a European standard developed by CEN that specifies the requirements for 90° welded end elbows made from titanium alloy, designed for pipe couplings with an 8°30' angle. This standard is specifically tailored for aerospace applications, ensuring high performance and safety under demanding conditions. The elbows are engineered to withstand nominal pressures up to 28,000 kPa and operate effectively within a temperature range of -55 °C to 135 °C. The use of titanium alloy guarantees durability, corrosion resistance, and light weight-critical properties in aerospace fluid systems.
Key Topics
- Material Specifications: Titanium alloy conforming to EN 3311, EN 3312, EN 3314, or EN 3315 standards, ensuring high mechanical strength and corrosion resistance.
- Dimensional and Geometrical Requirements: Precise tolerances and configurations for the 90° elbows according to EN 3275 with strict controls on surface roughness and internal surface finishing (0.8 µm surface roughness, radius R = 0.3 to 1.0 mm).
- Surface Treatment: Welded ends have a minimum untreated surface length of 10 mm. Threaded and sealing surfaces require dry lubrication as per EN 2491, applied on abrasive-blasted surfaces for optimal sealing and joint integrity.
- Pressure and Temperature Ratings: Designed for nominal pressures up to 28,000 kPa and temperature ranges from -55 °C to 135 °C, suitable for challenging aerospace environments.
- Marking and Traceability: Components are marked according to EN 2424 to ensure traceability and compliance with aerospace industry identification standards.
- Threading and Couplings: Adapted for pipe couplings with an 8°30' angle following ISO 5855-3 for MJ thread fittings, ensuring compatibility and secure installation.
Applications
SIST EN 4019:2002 components are highly suited for aerospace fluid systems where reliability, safety, and weight-saving are priorities. Typical applications include:
- Aircraft Hydraulic Systems: Providing reliable fluid conveyance in critical hydraulic circuits subject to high pressure.
- Fuel Systems: Handling fuel flow with precise leak-proof welded connections that withstand temperature and pressure variations.
- Environmental Control Systems: Ensuring robust and lightweight piping for air conditioning and pressurization circuits.
- Engine Systems: Serving as integral connection points in fuel, oil, and cooling fluid supply lines exposed to harsh thermal conditions.
