Hastalloy or C/S PTFE for Hypo
Hastalloy or C/S PTFE for Hypo
(OP)
I am in the process of designing a pipe run for sodium hypochlorite, 14/15%, ambient temp, up to 6bar.g., about 150m long.
I am considering 1" PTFE lined carbon steel or small bore 1/4" hastalloy-c276. Does anyone have any advice for the most ecomical material for a hypo line or experience of use of these ,aterials for hypo duty.
Best regards,
Pete.

Maybe someone else will know for sure, but you may be able to get away with PVC, which would be the cheapest way to go, but without time to go through the conditions, I'm not sure. I am sure that I have provided hypo lines in PVC before. If I get a chance, I will take a look at the conditions and see if it will be OK for your application.
If you can go with 1/4" line size, why not 316SS or PVC tubing? There may be a compatibility issue with SS, but I am not entirely sure.

Do you have any contact for Titanium tubing, 1/4" and 1/2" to supply in the UK?

Yes, SS (whether 304 or 316 ) totally unsuited for above service.

Thanks to everyone for the input on the SS, I wasn't sure, I just knew that I have never seen it done.

We used Ti tube, fully welded with pulled bends and the spec changed to U-PVC either end, at valves, drain points and pressure relief. Although the fittings are expensive where the spec changes overall it was the cheapest option.
