Tapecoat
6025 Gray
Pipe & Pipeline Coating
Cold-applied coating in tape form
for high temperature pipeline service.
Basic Use
| High
temperature tape for above and below ground pipeline corrosion
protection.
Tapecoat 6025 Gray High
Temperature tape with a MAF® backing is designed to protect
above and below ground pipe fittings, tanks, insulated steam
lines, and other metal surfaces from corrosion and electrolysis.
This protective coating performs well over a wide range of
in-service temperatures up to as high as 250°F (121°C) in
constant or peak load operating conditions. Tapecoat 6025 Gray
may be applied to new pipelines and to pipelines in service and
operating at elevated temperatures. |

Composition
Tapecoat 6025 Gray is composed
of a specifically formulated MAF® backing and a synthetic
elastomeric, temperature resistant coating.

Surface Preparation
 Surface
must be clean and dry. SSPC-SP3 Power Tool Cleaning is recommended to
remove any loose rust and scale, dust or dirt. Oil, grease and all other
residue are to be removed from pipe surface per SSPC-SP1 Solvent
Cleaning. SSPC-SP6 Commercial Blast Cleaning is also acceptable.
Application
- Priming: If operating
temperatures do not exceed 180°F (85°C)
TC
Omniprime is the primer
of choice.
TC 7000 Epoxy has been developed specifically for use with
Tapecoat 6025 Gray when service temperatures are between 180°F and
250°F (85121 °C). Either primer may be hand applied by brush or
roller. Let TC Omniprime or TC 7000 Epoxy dry before applying Tapecoat
6025 Gray.
- Tape Application: Tapecoat 6025
Gray is applied by hand, with the
Tapecoat Hand Wrapster
#3, or by
plant or over-the-ditch tape wrapping methods. Tapecoat 6025 Gray is
spirally wrapped in two layers. Wrapping tension is to be maintained
to obtain conformability of the tape to the surface being coated.
