The ROTA Ultrasonic Testing Machine Series
GE Sensing & Inspection Technologies supplies the 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 6000-8000 rpm provides highest
productivity rates.
In addition to defect detection, ROTA systems can also be
used for geometry checking. ROTA series systems are well
known for high test accuracy, repeatability of results, and
test speed. Flaw-type defects throughout the material cross-
section, 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 computer-
controlled, parallel scanned inspection electronics systems
are used, depending on the equipment configuration. Many
test standards require a second, independent physical test
procedure. GE Sensing & Inspection Technologies fulfils this
specification via the integration of eddy-current test systems.
Nonferrous tube testing
GE Sensing & Inspection Technologies’ ROTA test systems
have their origins in high-precision testing of tubes and
heat-exchanger tubes for nuclear applications. The ROTA
25 and ROTA 45 Z inspection systems are designed for this
dimension range. The ROTA Z is a derivate from the standard
ROTA line with central probe adjustment capabilities for
fast changeover times. The 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 cross-
section, including internal and external diameter quality
and eccentricity. These systems are in use with virtually all
manufacturers of nuclear piping around the world.
Testing of hot-processed tubes and bars
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 Sensing & Inspection
Technologies meets these requirements with its ROTA S
systems. In the ROTA S series, a special water routing and
cleaning system reliably removes particles from the probes.
The 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 ROTA systems, the ROTA
S features a central probe distance adjustment system
providing extremely fast change of material dimensions.
