Pollycote - 50
|
Pollycote - 50 is a pipeline anti-corrosion tape for use where small diameter pipe, low in-service temperatures and/or backfill demand the use of tape with a low mechanical performance. It can be used on larger diameter pipes, or for higher temperatures, when an outerwrap is employed.
