Mannesmann is a leading global network for steel tube technologies. In partnership with Salzgitter AG, we develop and manufacture highly specialized precision, line, and large-diameter tubes for the most demanding industrial applications. Our particular strength lies in our technological depth: From material development and customized manufacturing processes to our in-house testing and research capabilities.
Mannesmann stands for steel tubes that perform beyond expectations. At Mannesmann Precision Tubes, we make an important contribution to this with our wide range of seamless and welded precision tubes. The exceptional precision of our steel tubes – with extremely tight wall thickness tolerances and minimal eccentricity – ensures safety and confidence, even under the heaviest loads.
For us, precision goes far beyond technology; it also means developing customer-specific solutions, delivering tailor-made products, and working together as partners to find the optimal solution. This is how we continually fulfill our shared promise: TRUST IN EVERY DIMENSION.
Exceptional dimensional accuracy
Very tight dimensional tolerances – often significantly higher precision than standard requirements – can be agreed upon for our pipes.
Quality Commitment
Consistently high and durable quality through extensive testing and comprehensive quality standards throughout the entire supply chain
Partnership
Close collaboration with our in-house research institute for customer-specific product development and continuous process optimization
One-stop solution
Seamless and welded tubes from a single source – combined with a reliable and robust supply of starting materials
Better fit
Drawn tubes in a closely graded series of dimensions, accurate to 0.01 millimeters, ranging from 4 mm to 120 mm
Mannesmannröhren-Werk
As part of the Mannesmann Precision Tubes Group, Mannesmannröhren-Werk in Saxony, Germany, sets the standard as one of the most efficient manufacturers of seamless hot-rolled tubes. Here, innovative strength, efficiency, and decades of expertise combine to form a strong foundation for the future.
Most of the steel tubes (hollows and finished tubes) are further processed within the group at cold-drawing plants for demanding applications around the world. In addition, the plant also supplies external customers.
