Denso Hotline Tape is composed of a synthetic fabric impregnated with a special blend of high
temperature petrolatum, mineral Þ llers and thermal extenders. It is backed with a thin high
density polyethylene Þ lm.
A speciÞ cally developed tape for use in high temperature applications. Ideal for pipe work above
or below ground, underneath pipe insulation or for pipes laid in concrete.
• Meets NACE RP0375-2006
• Service temperature up to 230°F for above ground (180°F for below ground)
• Applied to marginally prepared surfaces (SSPC SP 2-3)
• UV resistant
• Resistant to water, acid, salts & soil organics
• Encapsulation of lead paint
• Contains no solvents
• Easy applications from arctic to tropical temperatures
• Ready for immediate service after application
Prepare surfaces by removing all loose scale, rust or other foreign matter in accordance to
SSPC SP2 “Hand Tool Cleaning” or SP3 “Power Tool Cleaning”. High pressure water wash of
3,000 - 7,000 psi is also suitable. Spirally wrap the tape with a minimum 1" overlap. For severely
corrosive environments, a 55% overlap is recommended. While wrapping, press air pockets out
and smooth all lap seams. Where tape rolls need to be joined, ensure that the overlap is sufÞ cient
between rolls to provide continuous protection. For below ground applications, an approved
Denso outerwrap is recommended. Note: for pipes with operating temperatures below 90°F
(32°C), a thin layer of Denso Paste HT may be applied to aid in adhesion.
Irregular surfaces such as valves, ß anges, etc. may require the use of Densyl Mastic or Denso
ProÞ ling Mastic. Refer to the product sheets for these speciÞ c products for information on
application and selection.
