Attention Steel Tank Dive Ops: HP Hot-Dipped Galvanized are back in production!

[lowviz]

You are a man who is both connected in the trades and has smarts in his hands.

I'd love to see a freshly sprayed tank dipped in triple salt or quadraflux and then baked at 850...

Something like going backwards one step in
this.

I've learned one thing over the years of being a member of this community, be as explicit and accurate as possible. In that light, the porosity of a sprayed coating is an issue with me. Porosity of Hot Spray

An even bigger issue is that the coating is just all the right stuff sprayed onto a tank. Don't feed me advertising BS. Here is what a hot-dip coating does to your tank: Hot Dip Zinc

-and lastly, for Tobin (bet he already knows) Fluxes can be found in here…

I'm calling BS on "Hot-Dip is back".

Keep in mind that while hot dipped is a thicker more durable coating porosity isn't really the problem one might think it is.

Part of the protection that Zinc offers steel is as a sacrificial anode exactly like the consumable "zincs" one finds on prop shafts and rudders etc on boats that are stored in the water.
If a zinc coating is scratched etc. or is porous it's not like a scratch in paint.

As an aside, galvanizing plants are just this side of hell. Always located deep in the least desirable neighborhoods they have parallel rows of giant heated vats of process chemicals many of which are quite dangerous. Typically they are open sided steel framed structures over the hot caustic and hot acid baths. These structures are dissolving from the effects of the fumes generated. Nasty places.

.... Flame spray is a very good second best.

Tobin,
Does the Flame Spray "cover up / distort" the tank date stamps? Sounds like a great alternative for my Fabers.

Hasn't ever been an issue for the tanks I've had sprayed.
