Safety of gas pipelines
We give our all to the safety of our transport network.
Every pipeline consists of a special, highly elastic steel.
Before it is laid, each pipe is checked. When the pipes have been joined together, independent inspectors go over every welded seam with X-ray or ultrasound devices. A coating of polyethylene around the pipes protects them reliably against rust. In addition, a negative electrical charge applied to the pipeline makes it into a cathode, also counteracting corrosion.
To ensure our high safety standards are upheld during operation, we regularly inspect our entire network from the air. To do this we use helicopters, which are also able to detect changes taking place around our lines. Our employees’ good eye for details in close-up completes the safety package. They drive or walk along the routes, carrying out spot checks using measurement devices.
Superficial inspection is not good enough for us.
So-called “pigging” allows us to keep a watchful eye on the interior of our pipeline system. Here, a remote-controlled device is inserted into the pipeline and travels along it. This lets us photograph or film the condition of our pipes from inside, inspecting every welded seam and connection.
