The Company

Salzgitter Mannesmann PrecisionFollowing the takeover of Vallourec Précision Etirage (VPE),France, by the Salzgitter AG, the new European market leader of cold-drawn seamless and welded precision steel tubes hasbeen founded under the name of Salzgitter MannesmannPrecision GmbH. As a leading European manufacturer SalzgitterMannesmann Precision offers a wide range of products and services with great scope for intelligent, tubing-related solutions.

The Group-StructureEffective synergies are a result of our integration with theSalzgitter Group ensure an outstanding efficiency - from the pre-material to the finished precision steel tube.The affiliated group companies ensure a comprehensive supplyguarantee regarding the complete value-added chain in production of precision steel tubes and is therewith the basis for the high performance in deliveries and customer satisfaction.Today, Mannesmannröhren-Werke (MRW) manages the Group'sTube Division. The Division has numerous subsidiaries and affiliated companies.

Applications of Multi Rifled tubesRifled tubes are used in high pressure boilers to eliminate the steam film effect due to theD. N. B. on the inner surface of the tube andraise thermal efficiency in the furnace walls.

Rifled tubes in a conventional boiler provide alarger margin of safety for natural circulationand assisted circulation and many economicaladvantages as:

• Reduction of weight for downcomers, headers, drum and connecting pipe

• Reduction of pumps power

• Reduction of framework weight

The concept

DNB phenomenon (Departure of Nucleate Boiling)

Besides standard designs, SMP has developedtubular solutions with small outside diameter,heavier wall thickness and improved rib profile(Siemens design and others) to further improveheat transfer and steam flow.

Over the last few years, designs have evolvedtowards more complex coal-fired stations(super critical and ultra-super critical). SMP hasbeen following that trend and developed pro-ducts accordingly.

Optimized profile

As clean coal technology requires ever more efficient powerplants, we propose to our most demanding customers personali-zed and optimized profiles to reach their expected performances,either according to Siemens’ or another design.

Besides avoiding DNB phenomenon, optimized profiles allow tosignificantly increase thermal efficiency.

We have been supplying thousands of metric tonnes of MultiLead Rifled (MLR) tubes for Ultra Super Critical power plants allover the world since 2006.

Three main criteria are key points of optimized profile:

• optimized lead angle

• increased rib height

• maximized plane rib flank

Optimized profile combines advantages of “A“ and “B“ profilesas lower rib width at top or a steep rib side angle.

Manufacturing process

Our manufacturing production flowFor over 40 years, SMP has been improving its manufacturingprocess to match ever higher requirements of its customers.

Our tubes are manufactured in our plant located in Vitry-le-François (France) by our skilled and experienced workforce.

Focus on ribbing processRibs are obtained through cold drawing process on a grooved plugfrom hollows supplied by SMP mills. After drawing and ribbingpass, tubes are heat treated to get specified metallurgical require-ments.

Before final cutting, tubes are 100% checked by Eddy Current and/or Ultrasonic test, depending on customer’s requirements.
