Hot bending and cold bending

We manufacture rings up to 3,500 mm external diameter with a maximum cross-section of 21,000mm² on roll bending machines. After bending, the rings are welded based on the strip flash butt-welding process constantly monitored by TÜV Nord. Our manufacturing program also includes shaped rings such as U, T and double T-shapes. The rings are strip-flash welded during this step with a power of up to 750 kV A and a subsequent forging pressure of up to 80 tons.

We manufacture rings with a resistance moment of 250 mm² and nearly unlimited diameter on a three-roll bending machine. Also included in the manufacturing program are shaped rings such as U, T and double  T-shapes. After bending, the flanges are strip-flash welded with a power of up to 700 kV A and a forging pressure of up to 80 tons.

We process other blanks from:

• Seamless welded rings
• Forged rings and blank disks
• Rings and blank disks fired from sheet metal or cut with plasma or a water-jet

We comply with all applicable specifications during manufacture.

We procure our input material from renowned suppliers from Germany and Europe. Take a look at our product range. We manufacture custom flanges for all application areas for you. Our competent service staff would be glad to answer your questions.
