solder contours, negatively affect costs and

quality of the final product. The answer to all

of these production problems is consistent

further development, eg of “solder batch

contours”, which can be implemented using

the forming technology of Rosenberger AG.

Both axial forming technology on the new

forming machine generation flexFORM RU8-

12-18 and radial profile rolling technology on

the rolling machine series RW20 guarantee

a high level of quality and performance in

rough industrial everyday operation or in

development centres.

Technical feasibility is now provided by

servo-electrical drives, since they are able

to move along complex ramps, in contrast to

the “blunt” moving forwards and backwards

of hydraulically driven tools. The flexForm

RU8-12-18 is not just a further development

and merger of Rosenberger’s predecessor

models RU8-12 and RU18, but rather a

completely new machine concept that

combines the advantages of its respective

predecessors while also containing many

years of experience and insights of the

company’s customers. The PLC-based

CNC control enables free programming of

all dimensions, paths and motions up to

0.01mm, forming force and speed. Servo

controllers ensure soft and precise running

through the programmable speed profiles for

best material flow control. Any and all material

properties can be included in programming of

the flexForm RU8-12-18 and considered in

the production process. Thus, not only simple

flanges, beads, reductions or expansions can

be produced, but complex pipe end shapes

can be generated as well.

Tool and programme changes can be

implemented in less than 5 minutes and are

measured fully automatically. The servo-

electrical asynchronous drives with an axial

working force of up to 180kN are low-

noise and -maintenance, energy saving

and do not generate great exhaust heat,

which leads to additional benefits in the

ergonomics and energy results.

A globally unique novelty is the compact

build and machine concept with its vertical

tool alignment (no more than 16, also multiply

rotating tools) and no use of hydraulics at

all; this makes the machine being easy to

transport and saves a lot of footprint space.

The offer includes the machine as a single,

hand-operated version, master-machine and

fully automatic forming device. The robot

connection can be used to best integrate the

machine into a fully automated system and

to use it flexibly. The fully automated joining,

eg of flanges, Ü-nuts, Ü-bolts, O-rings, and

holders is a standard application. The model

version DT (DoubleTool) enables concurrent

processing of two parts, which doubles the

daily output or cuts the cycle time in half.

Depending on task and parts geometry,

the clamping jaws can be installed to act

vertically or horizontally.

The clamping unit, type of tool change

and force of the axial, servo-electrical

asynchronous drive can be selected and

set up in modules. Possible attachment jaws

enable protection of pre-formed contours

or multiple contours. Several rotating tools

can also be set up, so that various rotating

processes like profile rolls, planes, chamfers,

thread shapes, etc can be processed with

great efficiency in a single programme run.

Rosenberger AG also provides the

required process-safe forming tools.

Interfaces that are already integrated, eg for

BDE-recording, network connection for data

back up and profibus interface for connection

to existing systems correspond to the latest

state-of-the-art. Remote maintenance can

reduce standing times and downtimes to a

minimum and thus warrant the basis for quick

reactions by Rosenberger’s service team.

This is not a pipe.

It’s actually an entry ticket to huge markets. Be-

cause what you’re looking at is a longitudinally weld-

ed pipe that’s been normalized to oil and gas pipe

standards. But there’s a catch. Normalizing isn’t

easy. Especially for today’s gauges and alloys. It de-

mands expertise in metallurgy, control software and

precise heat delivery.

The good news however is that these are areas in

which we specialize—making us a leader in pipe

weld-seam normalizing. Also, with more than 50

years’ induction heating experience, we’re experts at

using technology to open new commercial opportu-

nities for our customers.

EFD Induction is Europe’s no 1—and the world’s

no. 2—induction company. Our systems are used to

weld, normalize, anneal, harden, temper, braze,

melt, forge, bond, cure and pre- and post-heat.

So whatever your pipe normalizing needs, you

can turn to us for a solution. And since we’re present

around the world, that solution is probably closer

than you think. Contact us today. There’s a vast oil

and gas pipe market out there. We’ll help you get a

share of it.

ing solutions at Fabtech 2011—visit us at Booth 348.
