What is super-rust?
|Super-rust is not a new plague, although some engineers have
implied that it is. Instead older steel without constantly sound maintenance
becomes increasingly subject to accelerated corrosion. With tough economic
times, maintenance is a common cost cut-back area that can lead to
super-rust. This means that super-rust isnít contagious as an airborne virus
may be. It also means that poorly cared-for steel pipe can be subject to
super-rust and to failure. (reference)
Three solutions provide the greatest steel gas pipeline protection from
- Maintain steel carefully using high-quality corrosion-resistant coatings.
A Web search will show dozens of coating products geared to help control
super-rust and regular corrosion as well. Repeat coating and steel viability
- Replace steel pipe before it reaches the end of its useful life span, as
specified by the manufacturer. Often this lifespan is set at 30 years.
- Consider replacing steel distribution lines with plastic materials that
wonít corrode. Newer plastics let utilities use them even in high-pressure
