Anticorrosifs Anticorrosion Corrosion sous isolation Revêtements protecteurs SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).

Résumé : |
Corrosion under insulation (CUI) is a well-known industrial problem that has been plaguing asset owners for decades. CUI represents one of the costliest corrosion factors for the oil and gas, petrochemical and general processing industries and can lead to unplanned shutdowns, maintenance repairs and even explosions on live plants. The risks which CUI poses have led to the adoption of many preventive methods aimed at determining best practice for minimising potentially catastrophic CUI issues. |
