We have been operating with a vac/coker since 09/2000. We process Merey crude. We think we are having accelerated corrosion on our Vac twr HVGO line (30" 5 cr - 1/2 mo; 1/4" c.a.), Overflash line (6" 9 cr - 1 mo; 1/8" c.a.), and our btms line (24" 5 cr - 1/2 mo; 1/4" c.a.) due to high concentrations of naphtenes. Our inspection services are using high temp transducers for online TML's, but we still burn them up and have doubts about the accuracy. Do you know of any accurate inspection technology available for these high temps (up to 800 F) for these lines and who may be able to assist us?

If you have a need for high temperature thickness measurement, you may want to check out our Ultrasonic EMAT technology. EMAT Products

will show you a number of products available, but for a portable instrument for field work, the temate thickness gage will do the trick. Here is a link to the brochure (PDF File) Thickness gage

We are also looking for increased accuracy levels at elevated temperatures (Up to 200 Deg.C). I have seen mentioned +1% for each 100 deg.F but can find no published data supporting this, it also seems like a suspiciously round number. Is anyone aware of a formula or graph that allows input of a thickness reading and temperature and converts this to eqyuivalent ambient temperature thickness. Ranges: Ambient to 200 Deg.C, 2 - 50mm, Stainless steel. I will post any progress I make
