Curtiss-Wright EST Group focuses on
'safety' and 'reliability' in Petrochemical
and Refining Plants
ince 1968, Curtiss-Wright EST Group has specialized in the design,
and manufacture of tools and systems to simplify maintenance
of shell & tube and air-cooled heat exchangers, as well
as test plug systems to expedite in-service inspection of pipe,
pipelines, piping systems and pressure vessels. These plugging
and testing systems have saved their petrochemical and refining
customers millions of dollars in equipment maintenance and
downtime.
Their flagship product, Pop-A-Plug Tube Plugs, offer a permanent
cost-effective tube plugging solution for prolonging lifecycles
and improving efficiency of air-cooled heat exchangers, condensers,
and boilers. A unique breakaway ensures a tightly controlled installation
force eliminating damage to tube joints and tube sheets.
Pop-A-Plug Tube Plugs eliminate welding and maintain a leak tight
seal under extreme thermal and pressure cycling at working pressures
to 7,000 PsiG (480 BarG), and are available in over 35 alloys,
suitable for aggressively corrosive environments.
In addition, to assist their petrochemical and refining customers
isolate/test piping during flange replacement and other pipe
repairs requiring welding, EST Group designs and manufactures
pressure testing & isolation plugs to expedite testing and/or isolation
of piping, tubing, and pressure vessels.
This product line includes their GripTight MAX Test Plugs for
high pressure hydrostatic testing at working pressures up to 15,000
PsiG (1034 BarG); GripTight Isolation Plugs for isolating pipe end
hot work from potentially explosive upstream vapors; and High Lift
Flange Weld Test Plugs for isolating and hydrostatically testing weld
joints of any welded flange-to-pipe connection. These plugs eliminate
the need to fill entire systems, significantly reducing time and
test media needed to perform testing.
Curtiss-Wright EST Group serves a global customer base within
refining, petrochemical, fine chemical, pharmaceutical, power generation,
oil and gas, and shipbuilding industries. With a large inventory
ready to ship and 24/7 emergency manufacturing available,
EST Group is here when you need them most!

A choice of solutions for
pressure regulation
Cashco has launched three new devices
for the control of gas pressure
T
he new ULR-1 ( " Un-Loading
Regulator " ) valve from Cashco is
more than an enhanced product. It also
brings clarification and new information,
says Clint Rogers, General Manager
of Cashco's Valve Division.
The ULR-1 was originally
marketed as the U1 by Kaye
MacDonald, which Cashco bought
in 1999. Unfortunately, the only
documentation for the U1 and
similar products was the original
schematics, which showed how
the tubing and fittings were to be installed,
Rogers says.
" Previously, a customer would have had
to locate the technical bulletin, work their way through its product
coder and then a separate product coder for the correct bill of materials
for the hookup, " Rogers explains. " Not any more. With these
new products, all of the information is in the technical bulletin and
the operating manual. "
As Rogers explains, the ULR-1 is a DA4 regulator with a Cashco
CA1 back-pressure valve mounted onto it. Using the inlet pressure
from the valve, the CA1 is set to control the outlet pressure of the
main valve. Because the outlet of the CA1 constantly exhausts into
the atmosphere, the media through the valve must be environmentally
safe gas such as oxygen or nitrogen.
For even more choice in pressure regulation, Cashco has also introduced
the SLR-1 and SLR-2 Self-Loading Regulators. The SLR-1
is a high-performance, pressure-loaded, pressure-reducing regulator
with a self-contained regulator mounted onto it. Inlet pressure
from the main valve is diverted to the pilot, which, in turn, reduces
the loading pressure to the cover dome in order to maintain the set
point of the main valve. The pressure inside the dome is static, so
gas is only released to atmosphere when the outlet pressure setting
is reduced or the system is shut down.

The new SLR-2 self-loading regulator is similar to the SLR-1,
but its loading valve is not self-relieving. Instead, the cover dome
bleeds through a filter and check valve back into the outlet of the
main valve. This feature allows the SLR-2 to be marketed for hydrogen
gas, natural gas and sour gas (NACE) applications.
