Krautkramer ROTA Systems Product Line
Name
GE supplies the Krautkramer ROTA systems which, depending
on the client’s requirements, can be configured for individual
manual, central or motor adjustment, and are notable for
highly repeatable results. A probe revolution rate of 60008000 rpm provides highest productivity rates.

In addition to defect detection, Krautkramer ROTA systems
can also be used for geometry checking. The systems are well
known for high test accuracy, repeatability of results, and
test speed. Flaw-type defects throughout the material crosssection, and divergences in the dimensions for internal and
external diameter, wall thickness, ovality and eccentricity can
all be detected in a single inspection cycle. A manual probe
fine-adjustment system is installed as standard. It enables
fast and repetitive adjustment. The equipment is fitted with
single or multiple probes, depending on the particular test
application. Single or multi-channel, manual or computercontrolled, parallel scanned inspection electronics systems
are used, depending on the equipment configuration. Many
test standards require a second, independent physical test
procedure. GE fulfils this specification via the integration of
Eddy Current test systems.

Hot-processed tubes and bars necessitate special design
features for test and inspection systems, in terms of surface
quality, fouling, coarse manufacturing tolerances, test
throughputs and test speeds. GE meets these requirements
with its Krautkramer ROTA S systems, a special water routing
and cleaning system reliably removes particles from the
probes.
The Krautkramer ROTA S series was specially developed for
hot processed tube with rough surfaces, bend tolerance
greater than standard API specification and including tubes
with upset ends. Unlike the conventional Krautkramer ROTA
systems, the Krautkramer ROTA S features a central probe
distance adjustment system providing extremely fast change
of material dimensions.

GE Krautkramer ROTA test systems have their origins
in high-precision testing of tubes and heat-exchanger
tubes for nuclear applications. Krautkramer ROTA 25 and
Krautkramer ROTA 45 Z inspection systems are designed
for this dimension range. The Krautkramer ROTA Z is a
derivate from the standard Krautkramer ROTA line with
central probe adjustment capabilities for fast changeover
times. The Krautkramer ROTA and ROTA Z systems are
conform to the extremely strict inspection requirements for
nuclear specifications and permit not only defect detection
but also complete geometrical checking of the tube crosssection, including internal and external diameter quality
and eccentricity. These systems are in use with virtually all
manufacturers of nuclear piping around the world.
