EN 10253 / DIN 2605 Elbow Dimensions
This chart gives EN 10253-2 butt-welding elbow dimensions in millimetres — 90° centre-to-end radius R and 180° return dimensions for type 2D, 3D and 5D elbows. EN 10253-2 (carbon / alloy) and EN 10253-4 (stainless) replaced DIN 2605 and are specified on European-design projects.
Teshi Group manufactures EN 10253 / DIN pattern butt-weld elbows in India alongside its ASME B16.9 range.

Notes
- All dimensions are in millimetres. Elbows are listed by DN and outside diameter D.
- Type 2D, 3D and 5D give bend radius R ≈ 1, 1.5 and 2.5 × D. 3D is the EN equivalent of the ASME long-radius elbow.
- 180° returns: C = centre to centre (2R); K = back to face.
- Values are nominal, compiled from published copies of the standard; blank cells (—) are values not confirmed from the sources available. Verify against the current edition before design, purchase or fabrication.
Reference information compiled from the published standard for convenience. It does not replace the current edition of the governing standard, which takes precedence. Verify critical dimensions and properties before design, purchase or fabrication. Teshi Engineers & Sales Promoters (P) Ltd accepts no liability for errors or omissions.

FAQ
EN 10253 / DIN 2605 Elbow dimensions: common questions
What is the radius of a DN 100 3D elbow to EN 10253?
A DN 100 3D elbow (OD 114.3) has a 90° centre-to-end radius R of 152 mm.
Is an EN 10253 3D elbow the same as an ASME B16.9 long-radius elbow?
Close but not identical: ASME long radius is 1.5 × NPS in inches, while EN 10253 3D radii are set per DN in mm. Check the table if the elbow must fit an existing layout.
Does Teshi Group make EN 10253 / DIN 2605 elbows?
Yes — EN 10253-2 / -4 and DIN 2605 pattern elbows in carbon, alloy and stainless steel, with 3.1 certificates.
