Corrosion-under-insulation (CUI) refers back to the exterior corrosion of piping and vessels that happens beneath externally clad/jacketed insulation end result of the penetration of water. by way of its very nature CUI has a tendency to stay undetected until eventually the insulation and cladding/jacketing is got rid of to permit inspection or whilst leaks ensue. CUI is a standard challenge shared through the refining, petrochemical, energy, commercial, onshore and offshore industries.
In the 1st variation of this booklet released in 2008, the EFC operating events WP13 and WP15 engaged jointly to supply directions on dealing with CUI with contributions from a few ecu refining, petrochemical and offshore businesses. the ideas are meant to be used on all crops and set up that comprise insulated vessels, piping and kit. the information disguise a risk-based inspection technique for CUI, inspection thoughts and suggested most sensible perform for mitigating CUI, together with layout of plant and kit, coatings and using thermal spray recommendations, forms of insulation, cladding/jacketing fabrics and safety guards. the tips additionally comprise case studies.
The unique record first released in 2008 was once very profitable and supplied an enormous source within the carrying on with conflict to mitigate CUI. Many individuals of the EFC corrosion neighborhood asked an replace and this has taken among 18-24 months to take action. with a bit of luck this revised record will proceed to serve the neighborhood supplying a pragmatic resource of data on the right way to video display and deal with insulated systems.
- Revised and completely up to date technical assistance on coping with CUI supplied via EFC operating events WP13 and WP 15
- Contributions from a couple of ecu refining, petrochemical and offshore companies
- Extensive appendices that offer extra sensible assistance at the implementation of corrosion-under-insulation top perform, amassed functional services and case studies
