Without an entry in the “Type of information” column: standard dimension. A dimension that EN 10253-2 specifies for this size.

Where exactly it is measured

outside diameter D: measured across the edge at the welding ends, not on the bent part
wall thickness T: measured at the welding ends – on the fitting body it may only deviate downwards, to table 12
bend radius R: radius of the centreline, not of the outside – it cannot be measured on the part itself, which is what B, W and Z are for
back-of-bend to centreline distance B, W, Z: measure in the plane of the welding ends – from the centre of curvature to the outer edge
nominal size DN: the customary pipe designation – it is NOT given in EN 10253-2 but comes from the pipe dimension world
inside diameter ID: clear bore – the standard defines it as D minus twice T
pressure factor (type A only) X: ratio of the pressure resistance of the fitting to that of a pipe of the same wall thickness
wall thickness at the intrados (type B only) T_int: measured on the fitting body at the intrados – T still applies at the welding ends and at the extrados
mass: guide value for estimating freight and loads, calculated from the nominal wall thickness

Tolerances (limit deviations): what range the standard permits

For each dimension the range that EN 10253-2 permits is given – minimum and maximum instead of the deviation that would first have to be worked out. In the drawing this is shortened to tolerance – the word everyone uses in practice. In technical terms the two values given are the limit dimensions of the dimension, their distance is the tolerance and the deviations from the nominal size are the limit deviations. The basis is clause 11.2 with Table 12 and Table 13, and clause 11.3 – where the standard specifies nothing, that is stated.

These dimensions have two limit deviations – which one applies depends on the specific part

For the following dimensions the standard specifies two limit deviations. Which one applies does not depend on the nominal size but on the specific part. Both cases are therefore written out.

This answer determines: out-of-roundness O_v.

out-of-roundness O_v – calculated as 100 · (Dmax − Dmin)/D, largest and smallest outside diameter in the same cross-section

Where is the out-of-roundness measured? (the standard allows more out-of-roundness on the body of the fitting than at the weld ends. The weld ends are the two straight, flat end faces at which the part is welded into the line – the body is everything in between, on a elbow the curved section, which inevitably becomes somewhat oval in bending. What is measured, in one and the same cross-section, is the largest outside diameter minus the smallest)

at the weld ends out-of-roundness Up to D 273.0 no separate limit is specified – but Dmax and Dmin must each lie within the limit deviation of the diameter, and that limits the difference by itself.
on the body of the fitting out-of-roundness at most 4 %
I don't know both cases remain

What the standard specifies beyond the dimensions in the drawing

The following requirements are not tied to any dimension in the drawing. They are set out here in the structure of the standard, under its own headings. The label on each line says what kind of information it is – a dimension from the standard, a statement of the standard, an acceptance criterion on the finished part, or a manufacturing requirement.

How to measure correctly

An elbow is identified by three measurements: outside diameter D and wall thickness T, both taken at the welding ends and not on the bent part, and the centre-to-end dimension. The bend radius itself cannot be measured on the part – that is what the dimensions B, W and Z are for. On a 90° elbow, measure in the plane of the welding ends from the centre of curvature to the outer edge.

outside diameter D: measured across the edge at the welding ends, not on the bent part
wall thickness T: measured at the welding ends – on the fitting body it may only deviate downwards, to table 12
back-of-bend to centreline distance B, W, Z: measure in the plane of the welding ends – from the centre of curvature to the outer edge
centre-to-centre dimension C: only on a 180° bend – distance between the axes of the two legs

A measured value rarely matches the table exactly. The dimension finder on this page shows the limit deviations of EN 10253-2 for every size.

What is an elbow?

An elbow is a butt-welding fitting that changes the direction of a pipeline. To be distinguished from it is the pipe bend: a component bent cold or hot from straight pipe to customer dimensions (formerly DIN 2609), used when no standard elbow fits. This is explained in detail in the elbow basics.

Old standard → new standard

Standards: from DIN 2605 to EN 10253

The old German elbow standard DIN 2605 has been replaced by the European EN 10253. For non-alloy and alloy steels with specific inspection requirements, Part 2 applies – the standard of this page and the standard in plant construction. Old and new versions run in parallel in the market; the overall dimensions are largely identical.

The standard has four parts, and which one applies is decided by the material: the structure of EN 10253 is set out in the basics. For stainless steels Part 4 applies – elbows in stainless steel.

Pressure factor

Worth knowingPurchasing explains

Type A and type B – what the difference really means

A fitting is a formed piece of pipe – bent, expanded, necked-in or drawn. In forming, material migrates, and in some places the wall becomes thinner or the shape carries the pressure less well than a straight pipe. That is exactly where the distinction starts.

Type A is the fitting with pipe wall thickness. At the welding ends and at the body it has the same wall thickness as the pipe it goes with. The standard states expressly that its internal pressure resistance is lower than that of a pipe of the same diameter, the same wall thickness and the same material. By how much lower is stated by the pressure factor – a percentage that the standard lists for every size in tables of its own. 80 % means: the part carries four fifths of what the pipe carries.

Type B is the fitting that does not weaken the line. It has an increased wall thickness at the body and thereby achieves the same pressure resistance as the pipe. How much wall is needed for that, the standard calculates in an annex of its own.

What this means in practice. With type B you simply calculate the line with the pipe wall thickness – the fitting is never the weakest point. With type A you have to know the pressure factor and either reduce the permissible pressure or choose a thicker wall from the outset. That is why the type belongs in the enquiry and not in the follow-up question – it is part of the designation, not an extra.

And it is not a question of material. Type A and type B exist in steel as in stainless steel – they differ in geometry and in the verification, not in the alloy.

Standard reference: DIN EN 10253-2:2026-07, clauses 7.1 to 7.3 (standard page 18) and DIN EN 10253-4:2025-10, clause 7 – both read from the page image. Annex B (calculation), Annex C (pressure factors type A), Annex D (wall thicknesses type B).

Type A and type B: the pressure factor

Version

Type A – reduced pressure factor

Same wall thickness at the welding ends and at the elbow body as the connecting pipe. The resistance to internal pressure is lower than that of the straight pipe of the same dimensions – successor of DIN 2605-1.

Version

Type B – full pressure resistance (standard: “for use at full service pressure”)

Increased wall thickness at the elbow body, hence the same internal pressure capacity as the straight pipe – successor of DIN 2605-2.

Type A is the standard commercial product; type B is chosen when the line is fully utilised in the calculation. At the welding end both versions are the same. What exactly the pressure factor X is and how it comes about is explained in the basics; the value for a specific size is given by the dimension finder above.

Bend radius

Designs 2D, 3D, 5D: the bend radius

The design says how tightly the elbow is curved: the bend radius r is a multiple of the pipe outside diameter d. The tighter the radius, the more compact the installation – and the greater the flow resistance and erosion.

Elbow designs by bend radius
Design	Radius	Properties
2 (2D)	r ≈ 1 × d	shortest installation dimension, highest pressure loss, strongest erosion
3 (3D)	r ≈ 1.5 × d	standard design in plant construction
5 (5D)	r ≈ 2.5 × d	most flow-friendly standard elbow, well piggable

Schematics of the three designs to a common scale and the selection criteria – space, pressure loss, erosion, piggability, stresses – are given in the basics on the designs.

Angle

45° or 90°?

A 45° elbow produces only about half the flow resistance of a 90° elbow. When that pays off, which guide values lie behind it and what speaks against the solution of two 45° elbows is explained in the basics on the angle.

Manufacture

Seamless or welded?

In the marking, S stands for seamless, W for welded. Both manufacturing methods can be suitable for pressure-retaining applications – what is decisive are pressure factor, material, wall thickness, testing and code, not the manufacturing method alone. In detail in the basics on manufacture.

Boiler tube elbows

What is a boiler tube elbow?

Boiler tube elbows are elbows in the dimensions of the boiler tubes to EN 10216-2 (formerly DIN 17175) – that is, in sizes such as 31.8 / 38 / 44.5 / 57 / 63.5 / 70 / 108 / 133 / 159 / 193.7 mm, which do not exist in the ISO pipe series. The material is typically P235GH (formerly St 35.8), the creep-resisting boiler grade for steam boilers, heat exchangers and power plants. Technically the same designs and rules apply as for normal elbows to EN 10253-2.

Tolerances and testing

Tolerances and testing (brief overview of EN 10253-2)

Centre-to-end tolerance ±2 to ±5 mm depending on diameter; diameter tolerance ±1 % (max. ±5 mm); wall thickness minus tolerance −12.5 %; inside diameter at least 80 % of the theoretical value; out-of-roundness at the elbow body permitted up to 4 %, shallow corrugations at the back of the elbow permitted within limits. From 3 mm wall thickness, elbows are supplied with a weld bevel (30°, root face 1.6 ± 0.8 mm). Documents: test report 2.2 or inspection certificate 3.1/3.2 to EN 10204. The edition of the standard in force and the order agreement are binding.

EN ↔ ASME

Worth knowingThe inspection body explains

At the welding end, the fitting is measured with the same yardstick as the pipe

The limit deviation for the outside diameter in EN 10253 reads “±1 % or ±0.5 mm, whichever is greater” – and the tube standards of the EN 10216 series carry the same sentence, word for word. Out-of-roundness coincides too: 2 % here as there. That is no accident but intent: the welding end is where the weld is made, and what meets there has to fit together.

Both families of standards therefore distinguish the same two places – the body and the ends. API 5L lists the columns “pipe body” and “pipe ends” side by side, EN 10208 states expressly that the limit deviations do not apply to the pipe ends because they are regulated separately there. And the fitting standard, conversely, expressly measures at the welding ends.

The wall thickness coincides too, where it counts. The lower limit deviation is −12.5 % for both – and that is the one that matters, because it decides the pressure resistance. Upwards, the fitting allows more: +20 % instead of +12.5 % for the pipe. The reason is the forming – material that piles up during upsetting does no harm. Above ⌀ 219.1 the pipe additionally grades its lower limit deviation by the ratio of wall thickness to diameter, the fitting does not.

Two differences remain, and both have a reason. The fitting caps its diameter limit deviation at ±5 mm – from ⌀ 500 it is therefore toleranced more tightly than the pipe. And above ⌀ 610 it demands 1 % out-of-roundness where the pipe allows 1.5 %. The fitting is the formed part – it has to adapt to the pipe, not the other way round.

Standard reference: DIN EN 10253-2:2026-07, 11.2.1.1 and 11.2.2 · EN 10216, EN 10208, EN 10217 and API 5L

Worth knowingThe inspection body explains

Below ⌀ 273, out-of-roundness has no limit of its own – and is limited all the same

Below ⌀ 273 (below 406.4 for the stainless steel part of the standard) the standard gives no separate limit for out-of-roundness – it merely says it is “included in the limit deviations for the diameter”. That sounds like a gap, but it is a calculation.

Every diameter measured in the cross-section must lie within the limit deviation on its own – including the largest and the smallest. If both lie within the same band, their difference can never exceed the width of the band. At ±1 % that is, by itself, the 2 % that the standard writes out expressly for the next size band – the graduation is consistent in itself, and the lowest step is not an exception but a consequence.

Two side notes belong to this: for small diameters the minimum value of ±0.5 mm applies instead of ±1 % – in per cent the band is then wider (at ⌀ 21.3 effectively 4.7 %). And above ⌀ 500 the cap of ±5 mm takes effect – the band becomes narrower than 2 %.

Own derivation – not a statement of the standard: derived from DIN EN 10253-2:2026-07, 11.2.1.1 and 11.2.2 – applies analogously to EN 10253-4 (threshold 406.4)

Worth knowingThe inspection body explains

The elbow body may be twice as out-of-round as its own end

At the welding ends the standard demands, up to ⌀ 610, at most 2 % out-of-roundness – at the elbow body, that is in the bent region, 4 % is permitted. Twice as much.

That is not carelessness but physics: in bending, the extrados is stretched and the intrados is compressed, and the pipe inevitably becomes somewhat oval in the process. The mandrel inside the pipe is there to avoid wrinkling and out-of-roundness – that is, to limit them, not to abolish them.

For practice this means: measure out-of-roundness where it is regulated – at the welding end. A measurement in the middle of the bend gives a different value, and that value is to be judged against a different limit.

Standard reference: DIN EN 10253-2:2026-07, 11.2.2

Worth knowingThe design office explains

What you can rely on is the minimum wall thickness – not the nominal wall thickness

An ordered wall thickness of 4 mm does not mean that there is 4 mm of wall everywhere. The standard allows 12.5 % downwards – so what is certain to be there is only the minimum wall thickness – at 4 mm that is 3.5 mm.

That is exactly how our tolerance sketch is built: only what you can rely on is hatched. The band below it is what may be there, but need not be.

And the point that is overlooked most often: the pressure factor given is already calculated with this minimum wall thickness. The wall thickness tolerance is therefore already contained in it and is not deducted a second time. Whoever deducts it again rates the part worse than it is.

Own derivation – not a statement of the standard: cross-checked against EN 10253-2, Annex B, which calculates throughout with the minimum wall thickness

Worth knowingThe apprentice asks

Why is the wall of an elbow thicker on the inside than on the outside?

Because in bending, the pipe experiences something different on each side. In cold or hot forming, the extrados is stretched and the intrados is compressed. Stretched material becomes thinner, compressed material thicker – the wall thickness at the extrados is therefore smaller than at the intrados.

For the standard this has a consequence that is easily overlooked: the wall thickness is measured at the welding ends, not somewhere along the bend. For the fitting body only the lower limit deviation applies – an upper one is expressly not specified there. So the standard cares that nowhere is there too little wall, not that somewhere there is more.

And that is why an elbow is not a “bent pipe with wall thickness T” either. It is a part that has wall thickness T at its ends and, in between, one that comes from the bending.

Standard reference: DIN EN 10253-2:2026-07, 11.2.3 with NOTE

Worth knowingThe warehouse explains

The stamp on the fitting is a certificate – this is how the warehouse reads it

The standard prescribes what must be on every fitting (hard stamping or needle marking, if possible not in the weld): the manufacturer's mark, the country of manufacture, the abbreviated standard reference (EN2 for the steel part, EN4 for the stainless steel part – written out in full is also permitted), the type (B mandatory, A optional), the material name or number, the test category (TC2 mandatory where both would be possible), W for welded (S for seamless optional), the heat number (in the standard: cast number) or code number and, where applicable, the mark of the external inspection body.

The dimensions follow a fixed order: for reducing tees and reducers D × T / D1 × T1 – first the run, then the branch or the small end. Whoever holds a part without papers at the rack finds the way back to the inspection certificate via the heat or code number – that is exactly what it is there for.

Two relaxations are known only to the steel part of the standard: below D 88.9 the marking may move to the packaging or a tag, and the diameter may be stamped rounded (42 instead of 42.4). The stainless steel part, in turn, allows additional methods such as laser or inkjet marking. So a missing stamp on the part is not always a defect – but it is a reason to keep packaging and papers together.

Standard reference: DIN EN 10253-2:2026-07, clause 15, Table 17, standard page 57 · DIN EN 10253-4:2025-10, clause 15, Table 15, standard page 52

EN ↔ ASME: the main differences

Functionally, Short Radius ≈ design 2D and Long Radius ≈ design 3D correspond to each other; ASME B16.9 has no 5D standard design. The radii are similar but not identical – ASME calculates in inches via the NPS, the EN specifies metric radii. The remaining differences (wall thicknesses, 45° elbows, LR as default) are given in the comparison EN ↔ ASME.

Frequently asked questions about elbows

What does EN 10253-1 mean for elbows?

Part 1 of the fitting standard covers non-alloy steel for general applications without specific inspection requirements; the standard in plant construction is Part 2 (with inspection requirements, type A/B). Version, material, test category and edition of the standard belong in the order text.

What is a 45° elbow?

A fitting for a change of direction by 45 degrees – with about half the flow resistance of a 90° elbow (guide value). Overall dimensions, radius and manufacturing method must match the isometric drawing and the piping code.

How is an elbow in P235GH to be classified?

P235GH is the most common non-alloy pressure pipe steel for elevated temperatures (formerly St 35.8). The elbow must be manufactured, tested and heat-treated to a suitable product standard – as a rule EN 10253-2.

What is a seamless elbow?

An elbow without a manufacturing-related longitudinal weld in the elbow body. Manufacturing route, heat treatment and testing must match the product standard and the order; “S” marks seamless, “W” welded.

How is the designation “DIN 2605” to be understood today?

A historical national elbow standard, replaced by EN 10253. Rule of thumb for translation: DIN 2605-1 ≈ type A, DIN 2605-2 ≈ type B; for new procurement, dimensions, material, inspection requirements and application are to be specified against the current EN edition.

standard dimension: D, T, R, B, W, Z, C · calculated: ID, X, T_int · calculated: kg · assignment: DN

DN: EN 10253-2 does not assign a nominal size to every size. Where the dash stands there is none – the size is ordered by its outside diameter.

Dimensions outside the preferred series

EN 10253-2 pairs diameter and wall thickness through a series number. The sizes below we carry with a wall thickness that is in no series for that size – or with two wall thicknesses that are each in the standard, but not in the same series. The dimensions are established in the same way as in the grid above. Where the standard gives its values through the series number, the cell stays empty.

Where a dash stands, EN 10253-2 gives the value through the series number – and this row has no series number. This affects the guide mass from the catalogue table and, on the pipe end closures, the pressure factor and the type B wall thickness from the annexes. Nothing is calculated in their place.

Order dimensions and values calculated by us; deliverable from stock or procured, availability on request. Limit deviations and figures from the standard: see the main table and the standard itself.

The dimensions given are nominal dimensions. The masses are guide values calculated from the nominal dimension and the wall thickness – the standard gives no masses. The text of the standard prevails. The German edition DIN EN 10253-2:2026-07 reproduces the European version EN 10253-2:2021+A1:2025.

Which editions this comparison covers

For the elbow, the comparison covers the editions from DIN 2605:1962-09.

Unlike for the fittings, there is no list of individual changes here: the way from the earlier sheets to today's European standard can only be described in context for this component. It is set out on Standards in comparison, together with the other components.

These entries say what the standard has changed. They say nothing about material, pressure rating, scope of testing or the condition of an installed part — and nothing about whether an existing part can continue to be used. That assessment remains with the specific plant.

Elbows by dimension – ask our warehouse

It shows the dimensions you need for an enquiry, an order and installation – for sizes we supply, checked against documents from manufacturing works and suppliers and against our own range. Each value states what kind of value it is: specified by the standard, calculated by us or customary in the trade. The currently valid standard is binding. It is available from DIN Media or from your national standards body. How we select our sources and keep them up to date: About this knowledge.
