Bridge Authorities using them on bridges,

We’ll explained George

Also used (much larger) on steel canal barges in UK, probably other boats ships etc. . the zinc is sacrificial and on canal boats usually requires replacing periodically.

We use them on submersible pumps too!

Pipelines for sure - zinc anodes

Actually it isn’t very smart. Zincs only work when totally submerged in water and it’s usually only in salt water and where there is a lot of industrialization like paper mills, chemical plants or any other industry that uses a lot of electricity. I ran 3 big zincs on my lobster boat and everyone else runs zincs in my area and they’re gone within 6 months but my area has 2 paper mills and 2 chemical plants within a 30 mile radius. In areas where there isn’t any industrialization lobstermen don’t even run zincs on their boats and they have no problems. Plus I’ve don’t think zincs work in fresh water either.

​@@mikehunt3222 Correct. Zinc works in salt water. Aluminum is used in fresh water.

Correct

Problem is zincs only work while they’re totally submerged, so when they drove the truck out of the water they did nothing. Plus I’ve never seen a zinc eaten away on a boat in fresh water. Some over educated government idiot must have come up with that bright idea.

... and another one for the Rotary Dial Phone in his Shoe ... LOL. And yes, the Zinc anode is to protect against "Galvanic Corrosion" (happens even when not around Salt Water ... corrosion works 24/7).

@@craigsowers8456 corrosion works 24/7 but zincs do not except when totally submerged and I’ve only seen them eaten away in salt water. The zincs on my outboard at the lake have been on there for 10yrs and still look like new. I’ve been using zincs on my lobster boat for over 35yrs now and they’re gone within 6 months. Zincs on my outboard in the salt water last about a year because the lower unit isn’t in the water all the time, only when I’m out hauling traps or using it.

@@mikehunt3222 Gotcha and sorry if I wasn't clear ... you have Lobster boats so guessing you're from the Northeast. "Road Salts" come into play and once galvanic corrosion sets in, it never stops (unless fully neutralized chemically); which is why painting or oiling over an affected surface will merely drive it deeper ... it is "organic" and needs Oxygen to survive. With this truck being a "Fleet Purchase" by the USG, the "options" are pre-selected as they don't know where the vehicle will be "stationed" ... so ALL of the Fleet will have the Zinc anodes.

@@craigsowers8456 I understand that but zincs won’t work on a vehicle unless the zinc on that vehicle is totally submerged in salt water at all times. If they’re launching a boat with the truck as soon as they pull that truck out of the water and the zinc is exposed to the air it stops working. I could put zincs all over the inside of my boat and they won’t do a damn thing because they’re not submerged in the water. The zincs need the water to attract the electrolysis to them, as soon as they’re out of the water they stop working and do nothing even though they’re attached to the metal frame, IT WILL STILL RUST. You could probably even look this up on google but I’ve known this and experienced this for over 35yrs. When I pull my boat out of the water for 3 or 4 months a year the zincs stop being eaten away and anything steel on the boat starts to rust even stainless, depending on the kind of stainless will start to rust a little.

Lol

no didnt you know its THE boss. i got a sign for dad a few yrs back "im the boss of this house." "and i have the wife's permission to say so."

Thank you! I was almost screaming at my IPad when i saw that. Also I haven’t used a pickle fork in years. One swift hit from the side and most tie rods will pop right off
