Mechanical joint-integrity
training courses for the CPI
The Academy of Joint Integrity (www.
academyofjointintegrity.com) has
achieved approval from the Institution
of Chemical Engineers (IChemE)
for a suite of theory and practical
training programs to support technicians
and engineers in the chemical
process industries (CPI). In addition
to its established ECITB-accredited
courses and CPD-accredited training
courses covering the management
of the integrity of flanged bolted connections,
the Academy now provides
five training modules approved by the
IChemE. Designed specifically for the
CPI, the training programs cover disciplines
such as hand torque/hydraulically
torque/hydraulic tensioning of
flange joints and bolted connections.
Training can be offered at the Academy's
seven U.K. locations, as well
as delivery on-site at customer facilities,
by utilizing the unique Flange Assembly
Demonstration Unit (FADU).
The Academy, which is part of this
company's global sealing industry
specialists, supports industry with a
comprehensive suite of joint integrity
and sealing expertise. This includes a
range of engineering services, such
as technical consultations, engineering
drawings, failure mode analysis
and latest flange integrity calculations
to EN1591. - The Flexitallic Group,

A fully-coated isolation gasket
that is also thin
Evolution iisolation gaskets feature
easier installation, tight sealing,
high-temperature operation, no
permeation, hydrotesting isolation,
fire-safety and chemical-resistance.
With a thinner, 1/8-in. design, Evolution
gaskets minimize the difficulties
often encountered when attempting
to install thicker isolating gaskets.
The full-coating encapsulation allows
the gasket to be hydrotested and left
in the pipeline with the same isolation
properties as before it was tested.
Evolution's proprietary coating is
extremely abrasion- and impactresistant
while providing chemical

resistance to H2S, steam, CO, CO2
and other chemicals often found in
oil-and-gas pipelines. This fully encapsulated
coating also prevents the
need for expensive exotic cores, as it
eliminates contact to exposed metal.
The Evolution gasket provides the
highest tightness parameters for any
product available in the market today,
according to the manufacturer. It also
provides the highest pressure rating
of any isolating gasket available.
Evolution gaskets can operate under
high temperatures (rated to 500°F).

These fluoroelastomers
enhance seal performance
This company offers AFLAS 100 series
fluoroelastomers to enhance
the performance and extend the life
of pumps, seals and valves used
in a variety of harsh processing applications.
AFLAS fluoroelastomers
- copolymers of tetrafluoroethylene
and propylene with high molecular
weights - are resistant to acids,
bases, solvents, hydrocarbons, sour
oil and amines, as well as to extreme
temperature ranges and high-pressure
environments. They are easily
compounded by open mill and internal
mixers. These compounds are
then fabricated into finished parts and
shapes using press molding, injection
molding, extrusion (photo) and
calendering processes. AFLAS 150P,
100S and 100H are FDA approved for
food contact in the A-H temperature
range. Classified by ASTM D 1418-01
as FEPM, AFLAS products do not deteriorate
under prolonged exposure at
200°C. - AGC Chemicals Americas
Inc., Exton, Pa.

Labyrinth seal increases
efficiency in severe service
The Arlon 4020 Labyrinth Seal
(photo, p. 17) has a controlled thermal
expansion over a wide range of
temperatures, and has a uniquely
engineered tooth profile that make it
a cost-effective and long-lasting seal
choice. Customer test results show
up to a 1.5% gain in efficiency comCHEMICAL
