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.

Profile pipes

The perfect basis for finishing and further processing
Flender profile pipes impress with the maximum precision in their external measurements, internal measurements and the thickness of their walls. The precision of the pipes and the pickling provide you with the perfect basis for blanking, punching, bending, lasering and even for sophisticated surface finishing.

Our profile pipes are just as much use in office, studio, and computer furniture as they are in fitting business premises and warehouse or shelving systems. The outstanding quality characteristics and our binding delivery loyalty ensure a seamless handover to manufacturing facilities for further processing.

Precision steel pipes

Maximum precision and minimum tolerances
The production of precision steel pipes requires a special know-how, since only extremely close tolerances are allowed in this field of application. Flender precision steel pipes impress with the maximum precision of their internal and external diameters, which can only be achieved thanks to the exceptionally consistent thickness of their walls. The result of very low ovality and exact straightness, Flender precision steel pipes exhibit a particularly high level of true-running accuracy. That is how we are able to meet the highest possible requirements for the smooth operation and operational security of your systems.
