The facts about corrosion under
insulation
Corrosion costs in the UK alone currently exceed GBP25 billion: a new publication now available from Pittsburgh Corning looks factually at the problems of corrosion under wet insulation
Some estimates state that corrosion costs in the UK alone currently exceed GBP25 billion - 3.5% of GNP per annum Using the correct products and technology can probably save around one-third of these losses

An Exxon ethylene plant has reaped the benefits of replacing its cryogenic-service pipework insulation with Foamglas Terostat from Pittsburgh Corning
Pittsburgh Corning, manufacturers of Foamglas cellular glass insulation has issued a new publication "Corrosion under wet insulation - the hidden danger".
Any insulation that is permeable acts like a wet blanket around a pipe if it is in contact with water and oxygen, as well as the acids or chloride concentrated in the insulation itself.
Thus corrosion will form underneath the insulation.
Foamglas is totally impermeable to moisture of any kind, resists the development of corrosion by minimising water intrusion and retention, does not contribute to the corrosion of carbon or stainless steels and becomes an integral component of a corrosion protection barrier.
Foamglas does not need to rely on secondary protection methods and is effective in the temperature range -270C to +480C.
The new publication looks factually at the problems of corrosion and discusses proven solutions.
