Round tube pipes
Over 100 years of reliability and precision
Flender HFI longitudinally welded pipes are put to use in a wide range of different sectors – in steel construction, in the piping sector or as smoke tubes for compression stresses at a range of temperatures. We also manufacture round tube pipes, support-roller pipes, boiler tubes and pipe ingots for our customers. Safely meeting all manufacturing norms is the bare minimum for us. In any case, we usually tend to exceed these requirements. Flender has now been a byword for tangible product quality for more than 100 years.
Our company is certified in accordance with DIN EN ISO 9001:2008 and is an approved manufacturer in line with DGRL 97/23 EG and AD2000.
