Erosion Velocity
A lot of the replies on this forum refer to new information, e.g. from the University of Tulsa. Back in 1984 I was working at Amoco's research lab in Tulsa, and we looked at API 14E. The results of this work appeared in a 1985 paper: R. Heidersbach, "Velocity Limits for Erosion Corrosion," Paper...- drrust

Corrosion of 316L
This looks like what happens to 300-series stainless when it stays wet and not clean. It you want to see pictures of stainless in atmospheric corrosion, contact the NASA Kennedy Space Center. They run tests on this material and on more corrosion-resistant materials in atmospheric exposures...- drrust

Internal corrosion in SS 316L tank at liquid interface
The above advice on painting stainless steels has a link to a BSSA site that discusses painting stainless in ATMOSPHERIC EXPOSURES. The closest parallel I can personally come up with is the several major oil companies I deal with that paint their stainless steel lines underneath insulation (the...- drrust

Cadmium Bloom?
Look at zinc bloom. The metals are almost identical in their chemistry and corrosion behavior. Many organizations still prefer cadmium despite the environmental and occupational health concerns, but, for most purposes zinc and cadmium are used based on customer preference. I recently talked...- drrust

Internal corrosion in SS 316L tank at liquid interface
The original post states that the corrosion is at the air-liquid interface. No cathodic protection system can work in the absence of an electrolyte, so it cannot protect any metal that isn't wet. The post doesn't indicate that the liquid level varies, so splash zone (still wet from waves or...- drrust

Why epoxy coated rebars?
This thread started with a question about epoxy coating and then went to stainless steel. Most of the corrosion in concrete literature in the United States is related to Federally funded efforts to stop bridge deck corrosion. In the 1970's the "answer" was to use galvanized steel...- drrust
