TASK-LINE DESIGN TASK-LINE BENEFITS

Through a proprietary process, FDA
approved, pure virgin PTFE resin
is compression molded around
and through a 304 stainless steel,
perforated metal insert. After oven
sintering, every gasket undergoes a
15,000-volt spark test to check for
pinholes. The porous-free PTFE resin
100% encapsulates the stainless
insert, isolating it from any fluid
contact while in service.

NO MORE FABRICATION;
EASY INSTALLATION

TASK-LINE gaskets are molded to size,
1/2” through 24” in class 150# and
300# ANSI ratings with a nominal
thickness of 1/8” or 3/32” (other
thicknesses available upon request).
Installation is quick and simple.
TASK-LINE gaskets are self-aligning
and seat easily to any flange in almost
any condition.

TASK-LINE gaskets have a temperature
range of cryogenic to 400°F (consult
factory for higher temperatures) and
are chemically resistant to: all acids,
all chlorides, all sulfates, all bleach
solutions, all solvents, all phenols, all
caustics, and all peroxides. TASK-LINE
gaskets are leak-free and bubble-tight
and can be used over and over without
sacrificing sealing ability. TASK-LINE
gaskets have zero corrosion rates
which contribute to lower life-cycle
costs when compared to envelope or
solid gasket types.

TASK-LINE PERFORMANCE

In terms of performance and longevity,
nothing comes close. When installed
between two flanges, the PTFE­encapsulated metal insert restricts the
PTFE from cold flow/creep while under
load. The metal insert prevents radial
flow of the gasket which eliminates bolt
retorquing after installation, maintaining
a tight seal even through repeated
temperature cycles. The strength of
the metal insert also provides critical,
blowout-proof protection. Another benefit
of TASK-LINE gaskets is the PTFE’s non­stick property which allows it to easily
release from flanges during disassembly
without any scraping.

PRESSURE-TEMPERATURE LIMITS

Task-Line gaskets have been tested in excess of the above
pressures. Consult factory for higher pressure applications.

LINED PIPE GROUNDING PADDLES

Putting safety rst.

RELEASE THE STATIC MONSTER

Special consideration should be given
to the transportation of flammable
liquids through linings that incorporate
a grounded metal backing, such as
a steel pipe lined with PTFE or other
plastic. The electrical volume resistivity
of PTFE-lined pipe is 1018 ohm-cm.
This value is characteristic of highly
insulating materials capable of
accumulating dangerous levels of
static charge for several hours, even
days. Materials having less than or
equal to 109ohm-cm are considered to
be static dissipative/conductive.

Due to the large, effective capacitance
of the PTFE against a steel housing,
large surface-charge densities may
be formed. These densities give
rise to highly energetic, lightning-like
sparks in rapid succession known as
propagating brush discharges. Such
discharges have the potential to ignite
most flammable atmospheres and can
even ignite some of the more sensitive

dusts. Pinholes in the PTFE liner
may also be formed by these strong
electrostatic charges. If left unchecked,
these pinholes will cause premature
pipe failure which will lead to chemical
leaks and subsequent environmental
concerns.

TASK-LINE DESIGN

Through a proprietary process, static­dissipating PTFE resin is compression
molded around and through a 304
stainless steel, perforated, metal insert.
After oven sintering, the porous-free,
static-dissipating PTFE resin 100%
encapsulates the stainless insert,
isolating it from any fluid contact while in
service. TASK-LINE lined pipe grounding
paddles have conductivity/static
dissipating properties (volume resistivity)
of less than or equal to 106ohm-cm.

NO MORE FABRICATION
OR GASKETS

TASK-LINE lined pipe grounding paddles
are molded to size, 1” through 6”
(other sizes available upon request)
in class 150# ANSI ratings with a
nominal thickness of 1/8”. The paddle
handle extends 2” above the flange and
is pre-drilled for grounding hardware
and cable (included). TASK-LINE lined
pipe grounding paddles self align and
seat easily to any 150# ANSI, lined pipe
flange and never require gaskets.

TASK-LINE BENEFITS TASK-LINE PERFORMANCE

TASK-LINE lined pipe grounding paddles
have a temperature range from
cryogenic to +400°F and are chemically
resistant to: all acids, all chlorides, all
sulfates, all bleach solutions, all solvents,
all phenols, all caustics, and all peroxides,
TASK-LINE grounding paddles’ unusual
non-stick property eliminates/reduces ion
formation, oxidation and scale build-up, all
of which can render alloy paddles useless.
TASK-LINE lined pipe grounding paddles
come complete in kit form with everything
needed for a quick and easy installation.

TASK-LINE GROUNDING PADDLES
ARE NON-CONTAMINATING

Independent laboratory testing has proven
that TASK-LINE grounding paddles are
non-contaminating and non-leaching.
This limits the possibility of process
contamination.

In terms of performance and longevity, no
other grounding paddle compares. When
installed between two lined pipe flanges
and grounded to a suitable earth ground,
TASK-LINE lined pipe grounding paddles
provide a path for static discharges to
exit the hostile atmosphere generating
inside the lined pipe. The strength of the
metal insert inside the grounding paddles
provides critical blowout-proof protection.
TASK-LINE grounding paddles have zero
corrosion rates along with much lower
procurement and installation costs when
compared to fabricated or competitive alloy
paddles. TASK-LINE grounding paddles can
also help protect instrumentation devices
from inaccurate readings and damage
when exposed to static discharges.

Kit form available and includes
everything needed for quick and
easy installation.

PIPELINE FLUID BLOCKERS

Nothing gets in. Nothing gets out.

TASK-LINE DESIGN

Through a proprietary process, FDA­approved, pure virgin PTFE resin is
compression molded around and
through a heavy-gage, 304 stainless
steel, perforated, metal insert. After
oven sintering, the porous-free PTFE
resin 100% encapsulates the stainless
insert, isolating it from any fluid
contact while in service.

NO MORE FABRICATION
OR GASKETS

TASK-LINE pipeline fluid blockers (line
blockers) are molded to size, 1” through
6” (other sizes available upon request)
in class 150# ANSI dimensions with a
nominal thickness of 1/8”. Installation
and removal are a snap with its
integral molded paddle handle. The
handle extends 2” above the flange and
has a pre-drilled 3/8” hole for tagging
(while in service) or hanging (while in
storage).

The handle can be factory painted for
identification purposes. TASK-LINE line
blockers self-align and seat easily to any
150# ANSI flange and never require
gaskets.

TASK-LINE BENEFITS

In terms of performance and longevity,
TASK-LINE pipeline fluid blockers set
the standard. Line blockers have a
temperature range from cryogenic to
+400°F and are chemically resistant
to: all acids, all chlorides, all sulfates,
all bleach solutions, all solvents, all
phenols, all caustics, and all peroxides.
TASK-LINE pipeline fluid blockers are
leak-free, bubble-tight, and can be used
over and over without sacrificing sealing
ability. TASK-LINE line blockers have
zero corrosion rates which contribute
to lower life-cycle costs when compared
to fabricated or competitive alloy
paddles.

TASK-LINE PERFORMANCE

When installed between two flanges,
TASK-LINE line blockers block out all
pipeline fluid. The PTFE-encapsulated
metal insert reduces any radial flow
which eliminates bolt retorquing after
installation, maintaining a bubble-tight
seal. The strength of the metal insert
also provides critical, blowout-proof
protection. Another benefit of
TASK-LINE line blockers is the PTFE’s
non-stick property which allows it to
easily release from flanges during
disassembly without any scraping.
