“RD-6: When is a tape not a tape?” by Nate Muncaster
In terms of modern pipeline protection, “tape” has very negative connotations . It is associated with failure as a result of disbonding, wrinkling and shielding on cathodic protection, all of which can occur once the tape has lost its adhesion to the surface. In the US market, multi-layer polyethylene tapes have more or less been dead technology for decades, now used by only small fringe of the industry.
In response, Polyguard developed the RD-6® Coating System – the “tape that is not a tape” – in the late 1980s. It differentiates itself from older tape in its application and performance, offering far superior adhesion and added resistance to elongation – a customized polypropylene mesh means it will resist wrinkling from soil stress. The coating is a self-healing, one-layer system which can be applied faster and more simply – it doesn’t need time to cure – than multi-layer tape systems. [Read more…]
