Premium threaded
and coupled
connection for
thermal wells
TMK has launched a premium threaded and coupled
connection targeted at thermal wells. The new connection,
TMK UP UltraTM GX, successfully completed the testing and
evaluation requirements of TWCCEP / ISO PAS 12835 for
290°C application. The pipes used for qualification testing
were supplied by Volzhsky Pipe Plant (VPP).
Thermal well casing connection evaluation protocol
(TWCCEP) requires extensive material testing, rigorous
finite element analysis, galling resistance test and thermal
cycle test, followed by limit strain and bending tests. The
FEA, galling resistance test and thermal cycle tests were
completed in-house at TMK’s R&D centre in Houston,
Texas, USA. The limit strain and bending tests were
completed at C-FER Technologies, Edmonton, Canada.
The new connection is already being promoted and offered
to customers in Canada for thermal applications.

Energy-efficient pumping and gentle
handling of sensitive process fluids
Alfa Laval SRU rotary lobe pumps
are engineered to provide reliable
performance, trouble-free operation
and energy efficiency for demanding
applications in the dairy, food, beverage,
personal care and pharmaceutical
industries.
Particularly suited to duties that require
contamination-free pumps to meet high
standards of hygiene, low-shear and low-
pulsation operation, the pumps handle
both cleaning-in-place and sterilisation-
in-place, and can be supplied with
thorough documentation to support
rigorous validation requirements.
The SRU rotary lobe pumps are
designed with features that maximise
performance and minimise the risk of
contamination.
These include a defined compression
front cover sealing, rotor nut retention
design, drainable pump head and ultra-
clean surface finishes.
Understanding of flow patterns
ensures high efficiency fluid transfer
with low pulsation, low shear and
low noise characteristics. Alfa Laval
employs computational fluid dynamics
(CFD) to establish exact geometry for
the rotors and rotor case. The SRU
features a robust gearbox construction
with heavy-duty shafts, torque locking
assemblies and taper roller bearings
throughout.
The SRU rotary lobe pumps comply
with EHEDG, 3-A, 3.1 and FDA hygienic
standards and have ATEX approval for
use in explosive environments.
