Flanges are components for connecting or closing pipes and their components. The connection points are connected with flanges in order to be able to easily replace valves, measuring instruments or pumps in a pipeline.
Flanges can be connected to the pipeline in various ways:
- Welded to the pipe or fitting/elbow
- Slid over the pipe and then welded to it
- As a loose flange, not fixed with the pipe, held by a pre-welded collar or pre-welded flange
We supply flanges suitable for all nominal pressures and pipe quality in accordance with EN and ASME.
