Can galvanized fittings be used on liquid chlorine pipelines?
Thread Content
There is a pressure gauge on the liquid chlorine pipeline, along with a tee and a needle valve. Regarding the threaded connections, can galvanized plumbing fittings be used for them?
Make sure that your pipeline contains liquid chlorine rather than wet chlorine, as the material used in galvanized pipes is carbon steel. Carbon steel has a certain degree of corrosion resistance to dry chlorine gas and dry liquid chlorine, but it is highly susceptible to corrosion by wet chlorine. Liquid chlorine is not suitable at 50°C, but it is suitable at 25°C
The boiling point of liquid chlorine is -34.6°C; it vaporizes into a gas at normal pressure. When designing pipelines for liquid chlorine, its low-temperature properties must be taken into account
No. Dry chlorine has little corrosive effect on carbon steel; however, since chlorine is a highly toxic gas, seamless pipes must be used in accordance with regulations. Galvanized pipes are all seam pipes, so it’s not possible.
