Coupling technology
STRAUB specialises in the develop-
ment of pipe connections and repair
products. The company claims to be
flexible and robust in aligning itself to
changes in the marketplace, which
can happen almost overnight. With
a network of business partners the
company, which belongs to the Aliaxis
group in Belgium, is active worldwide.
The technical benefits of using pipe
couplings include a flexible and stress-
free connection that also compensates
tolerances of pipe ODs.
The couplings dampen structure-
borne noise and vibrations and
compensate for thermal expansion.
The coupling seals work progressively,
ie the contact pressure of the sealing
lip increases with increasing internal
pressure.
With quick and easy installation, the
pipe ends need no preparation. As there
is no welding or adhesive use, neither fire
nor explosion protection measures have
to be taken. Various types of coupling
are available to meet the demands
of different industries and installation
conditions: axial restraint and flexible,
one-part, two-part or foldable, as well as
couplings for connecting different pipe
materials, such as HDPE.
If secure and permanent pipe
systems and pipe connections are
required, Straub supports the customer
individually, by offering engineering
solutions and on-site installation.
Based on the original Straub coupling
technology, and in close cooperation
with the customer, the right coupling is
developed that fulfils the project-specific
specifications.

Ultrasonic testing with immersion control tank
PROVEA recently delivered a new
ultrasonic testing bench. The main
developments concerned the UT
control tank and the tube conveying and
guidance systems for helical motion of
the tube.
The full immersion control tank is
based on a stainless steel structure
featuring specific guidance parts for tube
axis/sensors. Five ultrasonic sensor
holders are included, with dedicated
and accurate positioning mechanical
settings (longitudinal, transversal
defect detection and wall thickness
measurement). Sensor mapping can be
set on demand.
New electrical positioners have been
added so that settings are registered in
the control panel. For one tube campaign
(OD, WT), positions of probes can be
registered in the panel. Mechanical
settings are called for a new campaign
(eg table height automatically set).
The tank is suitable for conventional
sensor application and phased array
technologies. 3-roll centring and
motorised systems have been designed
specifically for the project, allowing helical
motion of the tube. The pitch chosen
is set using centralised angle rolls.
Automated speed regulation is ensured
between each roll of the unit. The new
design also enables a large tube range
capacity. Mechanical pinions ensure an
identical distance between each pair of
rolls in contact with tubes.

Fluid solutions for tube manufacturers
QUAKER Chemical Corporation, a
chemical supplier focused on tube and
pipe manufacturing, will feature the new
Quakercool® 700 series platform with
emphasis on its threading performance
for the mechanical, structural and OCTG
tube and pipe process fluid applications.
The range includes Quakercool 730
TP for standard threading, Quakercool
750 TP for premium threading, and
Quakercool 770 TP for ultra-premium
threading.
Depending on the challenge and
complexity of the threading process,
these multiple solutions can help extend
tool life and, in turn, minimise tool and
insert wear costs. The metalworking
coolants in the Quakercool 700 series
are high-performance, mineral oil-free
micro-emulsions with a flexible modular
design for compatibility with upstream
chemistries and downstream coatings.
It is a single product technology for use
in multiple operations and with various
substrates. In addition to thread cutting,
the fluid solutions can tackle roll forming
and hydrotesting.
Quaker offers a ‘front-to-back’ range of
integrated processing fluids and coatings
for seamless and welded tube and pipe
manufacturing. At the front end, the
company provides fire-resistant hydraulic
fluids, speciality greases, hot forming
and rolling lubricants, and metalworking
fluids, while at the back end it has a
wide range of corrosion preventives and
transport coatings, including solvent-
based, water-based, and ultraviolet
coatings.
Complementary to the products,
Quaker’s application expertise can
assist in the entire tube and pipe making
process, from casting, forming and
finishing to coatings.
