It is a problem ? Heater tube indication FERNANDO VICENTE 1/15/2008
Dear All, i am having some doubts regarding to inspection in a tube from fire gas heater in a refinery.
On the tube there are a difference temperature indictation with a rectangular shape, i suppose that is a false indication, but when you see on the tube, there are nothing rare.
Do you have a suggestion?
Kind Regards
FErnando

Dude, you gotta get that camera up in there. You are WAY too far back. Don't be shy. Stick that bad boy up in there and take another pic. Then we'll have a looksee.

BTW, what camera are you using?

Dear Michael,

I don't think your camera is equipped with a high temperature calibration suitable for furnace tube inspection. The temperature scale on the right of your image does not reflect the actual firebox temperature range.
