| 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 sufficient between rolls to
provide continuous protection.
Irregular surfaces such as valves, flanges,
etc. may require the use of Densyl Mastic or Denso Profiling Mastic. Refer
to the product sheets for these specific products for information on
application and selection. |
