Lifting slings for pickle process
Lifting slings for pickle process
(OP)
Looking for the impossible here.
Lifting slings that can stand up to being submereged in HF / Nitric mix, then Lime neutralization. Polypropelene, Nylon and 304 stainless all poor performers. Any suggestions would be appreciated. I can provide more information if required, though this is not a project of mine, simply putting the "feelers" out there.
Cheers

Yes we looked at SS but there are some concerns around compromising the safety factor of the chains over time. We are lifting up to 9000lbs of product and immersing them into the acid then lime tanks. It seems we have slings that are good for one or the other, but not both.

Perfluroaloxy- available in cord. PTFE- Teflon has similar resistance but I don't think its available in cord. And there another high fluorinated polymer with similar broad resistance.

Not as cheap but you never submerge your lifting equipment more than the one time.
Just a thought.

You will need to re-sling the loads after rinse and before neutralization.
Sorry.

I did have your contact information to discuss this very issue, though like many things, I miss-placed it!
