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.
