EN 4183:2001 - Aerospace series - Pipe coupling 8°30' in titanium alloy - Elbows 90° welded ends

Overview

EN 4183:2001 specifies the characteristics of 90° elbows with welded ends for pipe couplings 8°30' manufactured in titanium alloy for aerospace fluid systems. The standard defines configuration, dimensional data, material references, surface requirements and marking. It applies to components rated up to 28 000 kPa and for service temperatures from -55 °C to 135 °C.

This standard is part of the aerospace series prepared by AECMA and adopted by CEN. It is intended to ensure interchangeability, safety and consistent quality for critical fluid system fittings used in aircraft and aerospace applications.

Key Topics

  • Scope and ratings: 90° welded elbows for 8°30' pipe couplings; nominal pressure up to 28 000 kPa; temperature range -55 °C to 135 °C.
  • Configuration and dimensions: Dimensional data are given by figure and table references (manufacturer options allowed where unspecified, provided EN 3275 type II qualification and acceptance are met).
  • Materials: Titanium alloy in accordance with the referenced aerospace material specifications (EN 3311 / EN 3312 / EN 3314 / EN 3315 as applicable).
  • Internal surface finishing: Required internal radius R = 0.3 mm to 1.0 mm and internal surface roughness 0.8 µm. Hand deburring is explicitly not permitted.
  • Surface roughness and external form: Surface roughness and other geometric features follow the figures and notes in the standard unless otherwise specified in design documentation.
  • Marking and designation: Marking follows EN 2424 (style A) and includes identification blocks and optional codes; see the standard for marking placement and content.
  • Technical specification and acceptance: Qualification and acceptance are governed by EN 3275, type II.

Applications

This standard is intended for designers, manufacturers, procurement and quality teams involved with aerospace fluid systems where reliable, high-pressure, corrosion-resistant fittings are required. Typical practical values:

  • Ensures compatibility for pipe coupling systems using the 8°30' interface.
  • Provides consistent material and finish requirements for titanium alloy elbows used in fuel, hydraulic or pneumatic lines.
  • Supports certification and traceability through standardized marking and referenced material specifications.

Benefits include improved interchangeability, predictable performance under the specified pressure/temperature envelope, and streamlined supplier evaluation.
