..., cryogenic and cyclic applications across -196 to 650° C/-321 to 750° F operational temperatures. TGPS coatings have demonstrated effective use of a two-step (primer-insulation) CUI mitigation coating approach operating up to 400° C/750° F, when compared to the traditional (CUI coating-fibrous insulation...

... ABSTRACT Corrosion Under Insulation (CUI) is a major challenge for different process industries. Today it is managed in many ways, ranging from full removal of insulation to minimal maintenance, including some inspection methods with insufficient non-destructive testing. These extremes...

... ABSTRACT Corrosion Under Insulation (CUI) on industrial piping is a major issue for the oil and gas industry. The potential influence of thermal and acoustic insulation materials is normally assessed through a series of individual laboratory tests on the insulation materials themselves...

... ABSTRACT Styrenic materials, utilized in subsea wet insulation, have been exposed in long-term tests for 12 months at elevated temperatures and pressures in seawater according to ISO 12736:2014. The performance of these materials under this harsh exposure regiment shall be presented...

... initiated on external surface when operating condition reaches room temperature. Degradation of cold thermal insulation provides accessibility for air-borne chloride to the pipe. Fatigue crack propagation through metal is driven by thermal stress during start/stop service operation period proven...

... ABSTRACT A metallurgical investigation of multiple, externally-initiated, in-service leaks on an above-ground, mineral wool insulated, oil emulsion pipeline concluded that the likely crack-initiating mechanism was stress corrosion cracking (SCC). However, the leaks occurred on an above-ground...

... ABSTRACT A simple set-up and methodology was developed to semi-quantitatively measure water transport (liquid and vapor) through intact and damaged insulation when a thermal gradient across the insulation is maintained. The main objective was to contribute to a better understanding of water...

... ABSTRACT Thermal insulation is used in operating facilities to conserve heat and protect against freezing amongst others. A consequence of insulating the equipment is the necessity to manage the introduced threat of corrosion under insulation (CUI). For CUI to occur, water and oxygen must...

... ABSTRACT Evaluation of subsea wet thermal insulation coating materials via exposure to seawater for a 12-month period at high temperatures and high pressures is presented in ISO (1) 12736:2014. This is a harsh exposure regiment which few materials have been evaluated against for such a long...

... atmospheric and/or wet insulation conditions. Steps can be taken to mitigate the risk of SCC, but since changes in the process or external conditions can occur over time, periodic unit reviews are beneficial. This paper also discusses setting the risk-based inspection ratings for these possible damage...
