Line pipes
Maximum quality for decades
Flender line pipes have been a byword for steel competence for generations. Whether oil, gas, water, or other solids – our steel pipelines provide the perfect connection between the production/handling facility and the consumption point.
The most cutting-edge checking devices and monitoring systems (in-process measurement) monitor welding and processing parameters to 100% accuracy. Whether district heating pipes or gas pipes, coating or casing – the quality of our line pipes can be seen across the board in DIN EN ISO 9001:2008, ISO 3182, API, Ghost and other standards.
