Hamburg elbows are used in various types of piping systems. This is a simple solution that allows for a quick and gentle change of the pipeline direction. Thanks to this, water, sewage or liquid media drainage systems are much more efficient, and their installation is also possible in small rooms with complex shapes. Today we will explain what a Hamburg elbow is, what its main applications and advantages are. We will also explain the model designations to make it easier for you to buy the right element in the future. We invite you to read!

What is a Hamburg knee?
The basic element of hydraulic installations are pipes - their disadvantage is that they only run in one direction, which is why they cannot be used to create any closed installation. For this purpose, you need to use fittings, and among them the most popular: the Hamburg elbow. It allows you to shape the pipeline, adjust it to the shape of the room and screw it to individual effectors.
The characteristic feature of the Hamburg elbow is its gentle bending angle. It is obtained in the technological process of expanding the pipe while simultaneously bending it. In this way, even very small radii can be created, but still ensuring laminar fluid flow inside.
Application of the Hamburg elbow in steel installations
Elbows are a key fitting used not only in home installations, but primarily in industrial ones. This is due to the advantages of this design:
- The smooth shape does not disturb the flow of fluids and gases, which is desirable in many processes.
- Steel water and gas installations are resistant to very aggressive environmental conditions. For this reason, they are suitable for transferring many industrial substances that would easily damage plastic installations.
- Made of strong and durable materials, Hamburg knees are very durable.
- A wide selection of sizes makes it easy to select the right element for your installation.
Considering in particular the durability and resistance to aggressive fluids and gases, this solution is most often found in industry. Hamburg elbows are used by the food, nitrogen or chemical industries in industrial installations. Steel pipelines work equally well for transporting water or gases.
Types of Hamburg knees
When looking at Hamburg elbows, you can notice several important differences between them. This can be the type of steel used for production, the bending angle, or the size (usually given in inches). There are also two types of elbows: seamed and seamless.
Hamburg seam knees They are used only in low-pressure systems, which is why they are rarely found. They are connected by welding, which can generate leaks in the pipeline.
Much more popular are seamless or smooth Hamburg elbows. They are made from a single block of steel, which makes them much more resistant to temperature changes. They also cope with high pressure, which significantly increases their area of use.
Hamburg knee connects installations with a gentle arc. Polish standards, according to which production is most often carried out, provide for a bending diameter of 2D, 3D and 5D, where the letter "D" denotes the nominal diameter. However, models manufactured abroad may differ in this respect from domestic ones.
Designation of Hamburg knee models
When thinking about buying a Hamburg elbow , you will certainly come across its marking. It is an alphanumeric string that precisely describes all the dimensions of the element. The ability to decode such a marking significantly speeds up the selection of the right elbow and its purchase.
- The designation begins with the product name. In this case, it is worth reading every word carefully - here we will find an indication of the type of the given model. Hamburg welding elbow or seam-sealed is intended for low pressures, while smooth or seamless is intended for high pressures.
- The name is followed by the angle at which the elbow turns. Most often it is 90°, but you can also find 45° or 30° models.
- The next place is the nominal diameter, or internal diameter, sometimes preceded by the abbreviation DN. It is given in millimeters.
- The diameter is followed by the wall thickness of the elbow. It is preceded by an "x" to separate it from the previous value.
- The pipe diameter is also given again in inches, at the very end of the description. In our offer you can find even very large 8 inch diameter elbows.
