I would like to ask what material the water supply pipe that is inserted under the acid level in the acid circulation tank is made of PTFE tube, with an opening at the bottom, or should there be a PTFE lining on the outside? How is the lifespan? Those with experience, what do you say? I think all-perfluoropolymer tubes should be good
F46, with a small hole at the top
Tetrafluoro is better; PP is also an option to consider
Perfluoro is better; at the same time, a small hole should be made at the upper end so that the liquid level inside the tube remains at the same level as that in the tank when no water is added
There are two types: one is pure tetrafluoroethylene, which does not have high strength and is suitable for use in stationary equipment; the other is a tube lined with and surrounded by tetrafluoroethylene.
Polytetrafluoroethylene tubes will do; they’re also cheap
Cast iron pipes, as well as those with inner and outer PTFE linings, are both suitable. It is important to check for corrosion at the levels of acid and gas/liquid, and to replace them regularly
Most manufacturers choose: steel-lined PTFE or PTFE tubes, with openings at the top to ensure gas-liquid balance inside and outside the tube
Where should the holes be made? Is there a picture I can take a look at?
Made from Xuanda stainless steel, it requires no replacement for many years – durable
