Company Siekmann offers you pipe bends made in Germany for decades.
Our product range includes seamless elbows with thick walls, special materials, special center to center distances, elbows with extended tangents as well as various angles (elbows in 180°, 90°, 45°, 24°, etc.).
We are particularly specialized in the manufacture of type B elbows according to the norm EN 10253-2 or 10253-4 or part 2 elbows according to DIN 2605. Our products are used in refineries, power plants, oil drilling platforms, heat exchangers, for mechanical engineering and so on.
Our products are manufactured according to two different manufacturing processes. For one, we manufacture elbows according to the “hamburger process”. Here the tube is pressed over a curved inner mandrel. The second manufacturing method is a hot forging process. In this procedure, the elbow is pressed into the appropriate shape by a die.
We supply elbows made of carbon steel, high alloyed steel or even stainless steel. Our extensive experience also in terms of heat treatment gives us the possibility to cover a wide range of materials. A list of materials can be found in the materials section.
Our production process is subject to stringent quality controls. During the manufacturing process, dimensional checks are carried out to detect early errors. Our company is supervised by TÜV Nord and is ISO9001 certified.
