ELBOWS
EN 10253, ASME B16.9
Our range of elbows covers a broad spectrum of measurements, standards and materials for all forms of use in piping construction – up to and including those applications with the highest safety requirements. We have a large variety of pipe elbows in stock available in accordance with standards EN 10253, DIN 2605 and ASME B16.9 , e.g. in 45°, 90° and 180°.
Unusual angles? Non-standardised radii? Limited tolerances? Not a problem for us – as your partner, we develop solutions with you and customise them to your needs, e.g. intermediate dimensions and size, special wall thickness and special elbows.

FAQ
The model describes the design of a fitting. For pipe elbows, the model type describes the bending radius:
- Model 2(D): short bending radius
- Model 3(D): standard bending radius
- Model 5(D): large bending radius
- Type A / Part 1: Reduced utilisation factor
The pipe elbow has the same wall thickness at the ends and on the rest of the body as a (straight) pipe with the same wall thickness. The resistance to internal pressure is generally lower than that of a straight pipe with the same dimensions. - Type B / Part 2: Full utilisation factor
The elbow has an increased wall thickness on the body and is therefore designed to withstand the same internal pressure as a straight pipe with the same dimensions.
Unusual degrees? Non-standardised radii? Restricted tolerances?
No problem - we specialise in customised product variants and individual customer specifications! We can manufacture elbows in type B (part 2) or with special wall thicknesses or special materials such as P355 for you in large and small quantities and supply also fully customised elbows.
We work with you to develop a solution for every application. Get in touch with us!
The Hamburg bending process describes the special manufacturing process that we use to produce our high-quality carbon steel pipe elbows. In the Hamburg bending process, the tube is formed into an elbow by pressing, using a tool with a suitable geometry (the so-called mandrel). The mandrel has a smaller diameter at the start of the bend, which becomes larger towards the end of the bend. The pipe is inductively heated before the area in which the mandrel is widened.
By continuously pushing the tube over the bent end of the mandrel, the diameter of the tube is expanded and the desired bend is created at the same time. This creates the final shape of the bend. The second half of the mandrel regulates the ovality of the tube and supports the bend during the forming process.
The Hamburg bending process is particularly suitable for ferritic materials. The main advantage of the process compared to the usual inductive process is the lower ovality. In addition, these elbows have a precise and very accurate inner diameter and a more even distribution of the wall thickness. The reduced need to add wall material also results in a cost advantage compared to the inductive process.
