Tees and crosses
BTH Elstar Sp zoo, founded in 1995, is
a trader and producer of a wide range
of stainless steel products for various
branches of industry. The company
produces tees according to standards
EN 10253-3 and DIN 11852, crosses
and collectors from stainless steel
within the size range DN20-DN400, and
pipe clamps in the size range DN10 to
DN250, with or without support.
Elstar’s leading product is the tee of the
EN 10253-3 standard. The company
recently improved production and
introduced a passivation process. Its
factory in Elblag in the north of Poland
is able to produce stainless steel tees
and crosses, as well as non-typical
pipeline elements such as collectors,
according to individual needs and
designs.
The company’s main goal is to deliver
comprehensive service, including
technical support and delivery of fittings
for the food industry, threaded fittings,
welded fittings, industrial valves and
pipes.

Phased array ultrasonic test system
to launch at Düsseldorf
Magnetic Analysis Corp (MAC) will be
launching the Echomac® PA, its first
ultrasonic phased array test system,
at Tube 2016. Complementing MAC’s
existing broad range of rotary ultrasonic
testers, a phased array test system
designed to inspect up to 180mm
diameter material has been supplied to
a European customer. A second similar
PA system, designed to inspect up to
100mm material, will be supplied later
this year.
Rotary ultrasonic testers can provide
higher speed testing when multiple
defect types are involved. However,
phased array technology has evolved
to the point where there are now some
applications that can benefit from its
uniquecapabilities.MAC’snewEchomac
PA system is capable of generating
normal incidence as well as clockwise
and anticlockwise shear waves
electronically from linear transducer
arrays, providing defect detection and
wall thickness measurement.
The focus of the element can be located
at more than one depth. This allows one
phased array multi-element probe to be
used for working at different angles of
incidence and different depths, instead
of requiring several single element
probes with different focal distances as
would be the case with traditional UT.
With these capabilities it is possible
to test a range of sizes, or fine-tune
incidence angles, without having tomake
physical adjustments to transducer
positions. With this introduction, MAC
states that it will become one of the few
companies that can offer either rotary
or phased array solutions, ensuring that
the customer gets the best tester for
their application.
In addition to the new phased array
system, MAC’s 500mm test systems
utilising rotary ultrasonic and flux
leakage technology will be featured.
The rotary test technique spins large
numbers of transducers around the pipe
as it passes through an enclosed rotary
test chamber continuously supplied
with pressurised water couplant. This
design offers higher throughput speeds,
quicker reconfiguration of transducers
for different diameter material,
repeatable test results and 100 per cent
coverage.
The 500mm UT tester can detect
longitudinal and transverse crack type
defects on OD and ID pipe surfaces,
and throughout the product’s cross
section, as well as lamination type
defects, meeting standards that require
finding artificial notches at a 5 or 10 per
cent level of the wall in pipe with any
wall thickness. The system, which also
features MAC’s wireless transmission
of test signals, can ensure compliance
with industry standards at throughput
speeds up to 1m/s.
The 500mm transverse and longitudinal
Rotoflux® flux leakage testers, combined
with the ultrasonic test, provide a more
comprehensive test, especially for
OCTG material. The addition of the
UT rotary to the magnetic flux leakage
testers provides complete all-direction
test capability and gives the user full
flexibility to optimise the pipe inspection
process.
The two flux leakage units can test to 5
per cent OD and ID notch levels in up
to approximately 12mm wall thickness,
and 10 per cent OD and ID levels for
thickness up to 15mm. The result of the
combined test technologies is a system
that is compliant with API 5CT and
5L, ASTM E570 and other standards,
including those that require ultrasonic
testing as the first method and a second
method at the discretion of the pipe
producer.
MAC’s experienced engineers will be
present at the stand to discuss the
company’s full range of ultrasonic
phased array, rotary and full body test
systems for tube and pipe, as well as the
new compact Minimac ® 55 eddy current
tester, which features all the capabilities
of MAC’s Multimac® software in a single
channel instrument.
