Don't get me started. There are photos on our web page about these waterlocks. The epoxy
coating will not work. Trust me on this...
I built a food
factory once, you might know the product as Weetabix. We had 12 rotating steam powered retorts that cooked the grain with a mixture of salt
and sugar. The "FDA" equivalent required us to use Stainless Steel
316L. They retorts lasted on average 6 weeks before springing a leak. I had one made with a low grade of SS, 3cr12, and it outlasted the others by a factor of 8. I then had one made up in boilerplate as an experiment
. It lasted years and years. The corrosion
you are talking about is a chemical reaction that erodes the steel
, the Cr that is contained in stainless steel must be in an O2 rich environment
. In an O2 depleted environment
, the crevasse corrosion runs rampant (same reason you never have a stainless swivel or shackle on your ground tackle, and others)
Gilana was built to Lloyds 100/A1 scantlings. Our whole exhaust
was stainless steel with rubber vibration bellows. The generator
too had a 55Lb stainless box aqualift, with enough capacity to hold 3x the runback of the exhaust system.
I have removed, welded, fixed patched and cursed, until one day I chucked them out and put in a GRP one on the Detroit, and a plastic one on the Gen. I chucked the SS exhaust lines and replaced with exh. hose. I have never looked back since. IF you epoxy coat, you deny oxygen to the steel, precisely by coating the steel you will destroy it.
Get yourself a Vetus, or equivalent lift
, and say good friggen riddance!
