Burner Tubes

Our range of production concerning burner and fire tubes contains more than 500 different types. We are working with highly heat-proof (up to 1150°C) and high-precision steel tubes, sheets and plates, highly resistant to oxidizing and deoxidizing sulfurous gases. We are also using unalloyed steel sheets/plates and rust-resistant and acid-resistant steel sheets/plates. We ensure closest tolerances.
We deliver parts for all areas of application and are able to realize nearly every possible deformation with almost all kinds of materials.

We manufacture according to our customer’s individual specifications for all areas of application in high and low volumes. We also deliver special models upon request.
