General Information
Overview
EN 4180:2001 is a CEN aerospace standard that specifies dimensions and wide tolerances for circular tubes made from titanium and titanium alloys intended for fluid systems. It covers tubes with outside diameters from 4 mm to 40 mm and provides recommended nominal sizes, linear mass data and the tolerances needed for aerospace applications. EN 4180 is part of the EN metallic materials series for aerospace and is linked to the general organization described in EN 4258.
Key topics and requirements
- Scope: Circular tubes for fluids in titanium and titanium alloys, wide tolerances, diameters 4 mm ≤ D ≤ 40 mm.
- Recommended dimensions and mass: Nominal diameter/thickness combinations and linear mass (kg/m) are provided in tabulated form (calculated using a reference density of 4.5 kg/dm3).
- Dimensional tolerances
- Diameter tolerances:
- 4 mm ≤ D ≤ 18 mm: ±0.06 mm
- 18 mm < D ≤ 30 mm: ±0.08 mm
- 30 mm < D ≤ 40 mm: ±0.10 mm
- Wall thickness tolerances:
- a ≤ 1 mm: ±0.10 mm
- a > 1 mm: ±0.05 mm
- Diameter tolerances:
- Length: Orders must specify whether tubes are supplied in fixed or random lengths; when random, minimum and maximum lengths shall be defined by the purchaser.
- Geometric tolerances
- Straightness, roundness and eccentricity are controlled and measured per EN 3848.
- Roundness deviation must fall within the outside diameter tolerances.
- Eccentricity must be contained within the wall thickness tolerances.
- Form and measurement: Form definitions and measurement methods are referenced to EN 3848; normative links include ISO 2964 for metric tube dimensions.
Applications and who uses it
- Typical applications: aerospace fluid systems - hydraulic lines, fuel and pneumatic tubing, environmental control and other fluid conveyance where lightweight, corrosion-resistant titanium tubing is required.
- Primary users:
- Aerospace designers and systems engineers specifying tubing for aircraft and spacecraft.
- Manufacturers and suppliers of titanium tubing and semi-finished products.
- Procurement and quality engineers verifying dimensional and geometric conformity.
- Test labs performing straightness, roundness and eccentricity checks.
