No Excuse for Cutting Corners on Corrosion Downstream

Corrosion is a major challenge and essential risk to contain for any oil and gas operator. Loss of containment can mean loss of process, loss of revenue, expensive repairs and – most importantly – a potentially major safety hazard. But while a breach in a cross-country pipeline can be a major incident and environmental risk, it’s another matter downstream. Different plant and processes are tightly packed together, with all manner of hydrocarbons and other combustible fluids boiling, cooling or flowing. Workers dart in-between, never more than a few dozen feet from a potential corrosion risk. In this environment, loss of…


Sensor Experts to Tackle Huge Corrosion Problem

The nuclear, renewable-energy and construction sectors also spend a fortune monitoring corrosion that is hidden under insulation. For the offshore sector, corrosion under insulation (CUI) on pipelines and other infrastructure is estimated to cost about £3.5 billion a year. Current practice relies on periodic removal of insulation in selected areas to check visually for problems – but that could be about to change. A new project involving Scotland’s Innovation Centre for Sensor and Imaging Systems (Censis) and specialist company CorrosionRADAR, a spin-out from Cranfield University, will explore the use of remote sensors to monitor corrosion continually without the need to…


Corrosion Under Insulation: The 7 Inspection Methods You Must Know About

As we discussed in our previous article, corrosion under insulation (CUI) is one of the most difficult corrosion processes to prevent. The reason for that is, by and large, no matter the precautions taken, water invariably seeps into the insulation and begins its dirty work—sometimes unseen until process leakage occurs. Data shows that about 60% of pipe leaks are caused by CUI. That’s not good. CUI is difficult to find because the insulation covers the corrosion problem until it is too late. Removing insulation, inspecting, and then reinstating the insulation after inspection is an expensive process. Inspecting without removing insulation…
