cathodic protection of steel tube flying leads
cathodic protection of steel tube flying leads
(OP)
Corrosion professionals. For subsea super duplex steel tube bundles (flying leads) we do not consider that connection with the protected host structure provides any cathodic protection apart from the first few meters of tubing. I recognise that cp of pipelines can be achieved over hundreds of metres using equi spaced anodes. Is it possible therefore to similarly protect small bore tubing bundles from each end only over a couple of hundred meters? We are able to coat each tube which would help reduce demand and of course we would only need around 0.5v to ensure protection. I would appreciate opinions on this and any use full texts or papers . Does this work? if not why not? If it does work why is super duplex always used where 316 may be suitable.
