Hydrochloric acid-resistant pipelines
Thread Content
At the installation site, there is a tower that uses water to absorb aluminum trichloride; when aluminum trichloride comes into contact with water, it reacts violently to form hydrochloric acid solution. A common problem at the site is that the 2\" atmospheric pressure acid discharge pipeline at the bottom often becomes clogged. Glass fiber pipelines cannot be cleaned using high-pressure nitrogen nor steam, and because they are quite long, it is not possible to inspect them for breaks. The current idea is to replace the 2\" pipes with 4\" pipes, as the inner surface of fiberglass pipes is quite rough; we don’t want to use fiberglass pipes. Is there a better type of pipe suitable for this environment?
Yes! Most organic synthetic materials will work. Such as ABS pipes, CPVC pipes!
PPR is also fine; there are now enhanced versions that can withstand certain pressures and temperatures below 90 degrees.
We use PPR, but it needs to be reinforced with fiberglass on the outside.
The tube can be reinforced with a steel mesh, offering acid and temperature resistance
