Syntho-Shield™
Tape Wrapping
Pipe & Pipeline Repair System
By
NRI Neptune Research, Inc.
A two-component wrapping system with exceptional
strength
for corrosion protection in soil or below the water line.
Product Information
The Syntho-Shield™
system is comprised of two components, the
Syntho-Glass®
material for mechanical and corrosion abilities as
well as a Petrolatum Tape undercoating for long term
corrosion protection. Syntho-Shield™ is an
innovative system that offers exceptional mechanical
and impact strength for underwater, underground and
above ground corrosion protection coating
applications.
Typical Applications
Corrosion,
Insulation, Sealing, and Waterproof Protection for:
- Pipes, flanges,
joints and valves for underwater, above and below
ground.
- Underwater pipelines
and platform rig superstructures.
- Concrete, steel and
wooden pilings, in the splash zone, above and below
water line.
- Jetty, bridge and
pier pilings, as well as, superstructure supports.
- Oil, water and
chemical pipelines for underwater, above and below
ground.
- Municipal water and
wastewater treatment piping systems.
- Industrial and
institutional plant piping and duct systems
Benefits
- Resistant to
temperature extremes.
- Easy to apply, no
mixing or messy clean up.
- Resistant to water,
acids, salts or soil organics.
- Can be applied to
wet surfaces and underwater.
- Minimal surface
preparation required.
- Quick, long term
protective coating, ready for immediate service.
- Contains no
solvents.
- Meets AWWA C217
Standard.

Preparation & Application
|
|
1.
|
Clean off all loose
scale, rust and other foreign objects. |
|
2. |
Apply the Petrolatum
Tape, a 50% overlap is recommended. Wrap tightly, firmly
press and smooth all lap seams. Remove any air pockets,
by molding with your hands, in the direction of the
wrap. |
|
3. |
Using the rubber gloves
supplied, remove Syntho-Glass® from the hermetically
sealed foil pouch and soak in temperate water, salt or
fresh, for 20-30 seconds. If the application is under
water, do not open the foil pouch of Syntho-Glass® until
ready to begin installation. |
|
4. |
Remove Syntho-Glass®
from the bag and begin wrapping tightly. A 50% overlap
is recommended. Squeeze and mold the Syntho-Glass® with
your hands, in the direction of the warp, removing
excess water and spreading resin until tacky. |
|
5. |
Note: For best
results, a UV protective paint coating is suggested on
applications where Syntho-Shield™ is exposed to the sun.
Applications on high impact zones, such as pier pilings
and splash zone coatings, require 8 layers of Syntho-Glass®
for maximum strength. |
