Denstone® Support Media to Customers Worldwide
Denstone® Support Media. Reliability Delivered.

aint-Gobain NorPro introduced Denstone® catalyst bed support
media for fixed catalyst bed applications more than 70 years
ago. Today, their extensive range of bed support media includes
Denstone 57, 2000, 99 and Denstone deltaP shaped media. This full
line of support media provides consistent, worry-free support for
catalysts of all sizes and materials.
Denstone 57 spherical support media is Saint-Gobain NorPro's
flagship product. It has remained an industry standard for over 70
years, providing consistent and unparalleled reliability as a support
media for numerous industrial applications.
Denstone 2000, a ceramic support media with an engineered microstructure,
offers increased survivability after thermal cycling and
rapid depressurization as experienced in severe hydroprocessing
applications.
Denstone 99 is a high-purity alumina support media for high
temperature, steam, ammonia processing and other petrochemical
applications where silica leaching is a problem.
Saint-Gobain NorPro is the only supplier producing innovative
shaped ceramic support media. Denstone deltaP shaped media is
available in three sizes: P1, P1.4 and P2. Its unique structure enables
an upper support layer with a typical diameter of 11.5 mm to
effectively retain a bed of 1.6 mm catalyst without any migration
into the support layer. This eliminates the need for micro-sized support
media, reduces the number of support layers needed, reduces
pressure drop and
increases the space

standardized qualification test methods prior to shipment.
These tight engineering controls ensure that every single batch of
Saint-Gobain NorPro's ceramic support media maintains the consistency
and reliability that the Denstone brand of support media has
become synonymous with.

Keeping Turnarounds on Track
with a Reliable Plugging Solution
Pop-A-Plug® Tube Plugs from Curtiss-Wright EST Group

any turnarounds may be scheduled months in advance, yet
plants still struggle to meet start-up and completion dates. By
some industry estimates, up to 90% of turnaround projects extend
beyond their scheduled time. Delays of even a few days can add millions
of dollars to the cost of a turnaround when factoring in reduced
productivity of the facility and additional on-site contractor labor.
For over 50 years, Curtiss-Wright's EST Group have been designing
and manufacturing products and systems to simplify maintenance
to shorten turnaround times for operation-critical equipment,
from shell-and-tube and air-cooled heat exchangers to pipelines, piping
systems, and pressure vessels.
A Permanent & Cost-Effective Solution for Tube Plugging
Shell-and-tube heat exchangers represent one of the most common
and critical pieces of process equipment in plants. In most environments,
heat exchanger tubes eventually degrade or leak as a
result of prolonged runs, impurity-induced fouling, and corrosive
fluids that run through the system.
One traditional process of sealing tubes involves installing tapered
plugs, often welded into the tubes with pre-heat and postweld
heat treatments. This process is both time-consuming and
unreliable. Tubes and tube sheets may suffer from circumferential
cracking after units are brought back into service from pressure
and temperature cycles that are common during normal operation.
Curtiss-Wright EST Group's heat exchanger plugging system greatly
Pop-A-Plug Tube
Plugs maintain
a leak-tight seal
without causing
damage to tubes
or tube sheets
minimizes delays
in equipment
maintenance during turnarounds by eliminating welding altogether.
The system includes G-160 Tube Testing Tools for leak detection
in shell-and-tube heat exchanger, boiler, and condenser tubes. These
tube testers can rapidly pinpoint tube leaks while providing a safer environment
for plant personnel with their patented gripper technology.
Once leaks are identified, Pop-A-Plug Tube Plugs deliver a permanent
and cost-effective plugging solution. Plugs install hydraulically
using a unique breakaway, eliminating the labor and time associated
with welding tapered plugs into place. Installed properly, Pop-A-Plug
Tube Plugs maintain a helium leak-tight seal without causing damage
to tubes or tube sheets. They can withstand extreme thermal and
pressure cycling at working pressures up to 7,000 PsiG (483 BarG),
and meet ASME PCC-2 (Article 3.12) recommendations for the inspection
and repair of shell and tube heat exchangers.
Pop-A-Plug Tube Plugs are available in wide range of materials,
including corrosion-resistant alloys, matched to the metallurgy of
the unit in which they are to be installed. Matching plug and tube
material mitigates thermal expansion/contraction issues, and undesirable
galvanic corrosion, ensuring the leak tight seal.
Curtiss-Wright EST Group serves a global customer base with an
extensive inventory ready to ship, and 24/7 emergency manufacturing
available. For more information, visit
