although they do both document corrosion losses and need for repairs. While corrosion assessment is necessary, it will not prevent future corrosion. Looking to the future, the Pipeline and Hazardous
Materials Safety Administration advised in mid-2011 that there should be “additional measures to prevent internal corrosion in gas transmission pipelines…corrosion control measures with clearly defi ned conditions and appropriate mitigation efforts….”. Internally coating fi eld joints should be an essential component when designing many types of pipelines because the environ- mental and fi nancial benefi ts address the corrosion threat directly, rather than in hindsight. Ultimately, corrosion prevention is only effective
PVC piping systems, man-entry (although this comes with its own life-threatening risks). Each should be explored to maximise economic, environmental and logistical angles. CRTS invites pipeline owners to consider the benefi ts of IFJ coating to complement or replace some of these alternatives because of the clear benefi ts corrosion prevention coating provides. Pipeline integrity is another important aspect of
corrosion prevention as it helps maintain a safe and healthy pipeline. Intelligent pigging and rehabilitation are important but neither activity prevents corrosion,
when corrosion is prevented. IFJ coating can clearly benefi t pipeline owners and protect the public trust while protecting the environment from mishaps, spills and unforeseen calamities.
