Thanks for you response Mcguire.
Welding is not an issue; the pipe is manufactured in modules to be connected by rubber sleeves.
The project engineer seems to be convinced that galvanized U-bolts will be OK. My concern is the materials are very far apart. The SS will be cathodic to the steel...
Thanks for your response CDC.
I realize that the trends in the coatings technology are quite dynamic, the issue of blasting and painting of fuel oil tanks tends to be one of the "moving targets" at the moment.
I can certainly appreciate the coating manufacturers position after many...
The standard you are referring to FS 595B is unknown to me. FS refers to Federal Standard Colors. The FS colors have a 5 digit numerical designation. The RAL standard is referred to as RAL followed by a four digits numerical code.
Your best bet would be to contact one of the paint...
Is it necessary to remove the inorganic zinc preconstruction primer in fuel oil tanks?
It is not common practice to do so. Most commercial ship owners choose not to paint the fuel oil tanks at all, some paint bottom and top only.
Is there a good reason for having this removed?
Any input will...
The SS piping system is located both on the exterior and the interior of a steel ship.
Weather exposed pipes will be coated. (Epoxy 12 mil)
Piping in interior spaces will be subject to condensation due to the temp gradient.
Can condensation be considered an electrolyte allowing galvanic...
Is there a standard or a guide for classification of corrosive environments in a marine environment, relative to various coating systems and their durability
Similar to ISO 12944, however, perhaps modified to specifically describe different areas on board a ship.
My job is to create a tool to...
