EN 10253-2 90° ELBOWS TYPE 2D (MM), DN 40, ASTM A234 WPB, EN 10253-2
Available materials: ASTM A234 WPB, ASTM A420 WPL6, ASTM A403 WP304/304L, ASTM A403 WP316/316L, ASTM A234 WP11, ASTM A234 WP22, ASTM A234 WP91, ASTM A815 UNS S31803.
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 dimensions from the standard; a dash (—) means the value is not listed. Verify against the current edition before design, purchase or fabrication.

Frequently asked questions
What is the difference between a long radius and short radius elbow?
A long radius (LR) elbow has a centre-line radius of 1.5 × NPS and is the default choice. A short radius (SR) elbow has a radius of 1.0 × NPS. SR elbows save space but add pressure drop and are not suitable for pigging.
What is the centre-to-end dimension of a 90° LR elbow?
For ASME B16.9 90° LR elbows the centre-to-end dimension A is 1.5 × NPS in inches. For example, a 6" elbow is 229 mm (9 in) and a 4" elbow is 152 mm (6 in).
What is the difference between a concentric and an eccentric reducer?
A concentric reducer keeps both ends on the same centre line. An eccentric reducer has one flat side. Eccentric reducers go on pump suctions with the flat side on top, so air pockets cannot form.
What is a 3D or 5D bend?
A bend whose centre-line radius is 3 or 5 times the nominal pipe size. They are usually made by induction bending and supplied with tangent lengths. 5D bends allow pigging in pipelines.
