Continuous shot-blasting installation
for external tube surfaces
Carlo Banfi, Italy, manufacture the ISTR series installation for external tube and pipe
shot-blasting for a maximum diameter of 20" (500mm). These installations are equipped
with throwing wheels arranged on the upper part of the blasting room.
A special conveyor system controls the
piece feeding, as well as rotation on
its own axis, so that the whole external
surface is exposed to the blasting action.
For larger diameters (up to 60") the
piece movement is achieved by sets of
wheels with inclined axis and fixed angles
compared to the tube axis.
For medium-large diameters (20" ÷ 80")
the throwing wheels are placed below the
piece level, so that the distance between
the throwing wheel axis and the surface to
be processed remains constant according
to the tube diameter. The inlet and outlet
pre-rooms are equipped with rubber
protections that prevent leaks of shot-grit
to the outside.

› The ISTR series of external shot-blasting
installations for tube and pipe
Olympus NDT, USA, has introduced Nortec
500, a new series of portable eddy current
flaw detectors. Available in three full-
featured, lightweight configurations, the flaw
detectors include a 6.5" diagonal full VGA
colour LCD screen for increased resolution.
Internal balance coils allow the use of
absolute probes without the need for
external balance coil adapters, and a
built-in preamplifier adds extra gain, when
required.
VGA output allows for optional ‘heads up
display’ for hands-free operation, while
the optional remote-null adapter adds
convenience and assures safety. The
Nortec 500 includes PowerLink™ for
automatic probe recognition and program
set-up, and a USB interface provides rapid
information transfer.
The Nortec 500 delivers basic, single
frequency eddy current inspection
including external outputs. The
Nortec 500S adds digital conductivity,
coating thickness measurement,
and rotating scanner use. The
Nortec 500D matches the 500S and
includes dual frequency capabilities.
The new detectors are packaged
in foreign object debris-free cases,
and feature a single Li-Ion battery
suitable for demanding environments
and intense applications.
The Nortec 500 series is suited to
the requirements of manufacturers
Eddy current flaw detectors in fields such as aerospace, and weld and
surface flaw inspectors in a wide range of
non-ferrous application environments.

Half pipes and U-pipes
Karl Theis GmbH, Germany, is a medium-
sized company supplying the chemical
process-equipment-construction, tank con-
struction, power plant construction and
pharmaceutical industries.
› Karl Theis produces pipes for heating and cooling
elements
The company produces and processes
half pipes for use as heating or cooling
elements for large tanks. The company also
specialises in the production of U-pipes.
which are one of the main components
of power plant construction and heat
exchanger construction. Also in the Karl
Theis range are coiled pipes, tube bends
and non-standard designs.
With a production area covering more than
4,000m2, the company shapes and welds
tubes of almost any ferritic and austenitic
material, with dimensions from 6mm to
323.9mm.
