Seamless steel tubes in perfection

In a blend of the best tradition and innovation we have perfected the manufacture of our tubes. Our steel tubes meet supreme standards - true to the Mannesmann name.

Top quality in action

We supply tubes to match the most stringent demands and stress criteria in numerous applications for vehicle construction, manufacturing industries and the energy sector.

Seamless steel tubes from Saxony

Company

Embedded within the Mannesmann Precision Tubes Group, the Zeithain plant operated by Mannesmannröhren-Werk GmbH makes seamless hot-rolled steel tubes (hollows and tubes finished to size). These are either sent on to the cold drawing mills of the Group or are sold directly to external customers.

Our plant in Saxony is one of the most efficient producers of small-size seamless tubes in the market and also operates Europe's most state-of-the-art push bench facility.

Production steps for the manufacture of a hollow

Storing of cast rounds in the buffer store

The cold-saws cut the cast rounds into billets

Heating of the billets in the rotary hearth furnace

The Three-Roll Piercing mill is the initial deformation

The flanging press fixes the hollow on the mandrel rod in preparation of the push process

The second forming stage is the push bench

The detaching mill increases the diameter of the hollow

The hot saws cut off the hollow head (for selected dimensions)

The walking beam furnace reheats the cooled hollows.

In the strech-reducing mill the hollow achieves the final diameter and wall thickness without iternal tool.

The layer saws cut multiple tube sections in customer lenghts.

History

Steel tubes production has a long tradition in Saxony, starting in 1907 with the commissioning of the first rolling mill for the first mill for seamless tubes in Riesa. In May 1961, the groundbreakig for the new tube of the VEB Stahl- und Walzwerk Riesa took place in Zeithain.

In 1965, the first hot-rolling mill, Tube Mill III (Plug MIll), went into operation, which was decommissioned in 1990. The second hot-rolling mill , Tube Mill IV (Push Bench), was built in 1978. Mannesmannröhren-Werke Sachsen GmbH, Zeithain, was founded in 1991 as a wholly owned subsidiary of Mannesmannröhren-Werke AG, Mülheim an der Ruhr. Since this aquisition considerable investments have been made in the plant technology of the Tube Mill IV. These investments were focused mainly on modernizing computer technology to improve the process control of the equipment.

The previous piercing press in Zeithain had been replaced by the combination of a Three-Roll Piercing Elongating mill (TPE) with the existing push bench went into operation in February 2008.
