PTFE Lining Inside the Tank

PTFE Lining Inside the Tank

PTFE Lining Inside the Tank

(OP)
Hi,
we are going to make Hydrofluoric acid reaction tank.
we need to apply PTFE lining inside PE Tank, we have no idea how to bond and joint teflon sheet
Suggest me how to apply PTFE ( Teflon ) inside the tank.

RE: PTFE Lining Inside the Tank

I agree with IRstuff, this is not something you do not want to do in-house without the right kinds of expertise. HF is an extreme hazard and this coating would need to be perfect in order to avoid a very bad outcome. You should search for a contractor with extensive experience in this field to perform that task.

RE: PTFE Lining Inside the Tank

Are you sure you need a PTFE lining?

What is HF's concentration that you are going to work with?

As per some chemical resistance tables, PE is resistant to 60% HF solution.

Either way, if you need to line an existent tank, I would consider buy a new HF resistant tank instead.
HF is a nasty, nasty chemical to work with and the last thing you want is a leak or a work accident because someone wanted to retrofit some old tank to save a few bucks.

Hi,
Safety first , you should investigate the feasibility with specialized contractors .
Consider the link attached to get advices :

I'm very surprised that you did not consider a new tank , for someone familiar with HF !!!

Good luck , HF is a very nasty product to be handle with extreme care , for the people and the environment.
