Hamburg Vorwerk-Logstor

At our site in Hamburg we bent a 16m long DN800/1100 pipe to over 20°, setting a new world record!

Sondershausen Isoplus

Celle

Misc

Immediately after bending, the pipes are ready to be lowered into the trench. As here on our site in Martigny, Switzerland. Pipes bent by us compared to KMR pipe unbent by us.

Pipes we can bend

 

In addition to district heating pipes, we also bend pipeline pipes without thermal insulation. We bend all regular pipe sizes according to API5L specifications with bending radii of 40xD for longitudinally welded pipes and 75% of 40xD for spiral welded pipes.

 

Our bending process is certified by the FFI (FernwärmeForschungs-Institut) and meets the requirements of DIN EN 253:2020-03.
