What material is good for sulfuryl chloride pipelines?
Thread Content
Our factory needs to use thionyl chloride as a raw material. What type of pipes, valves, and pumps would be suitable? The polypropylene materials I used didn’t work for long
It is recommended to use fluorinated lining pipes, fluorinated lining valves, and fluorinated lining pumps, as their corrosion resistance is much higher than that of polypropylene!
Is the poster using PP material? I’m also planning to use reinforced polypropylene for the pipes. The manufacturer supplies the reagents in HDPE containers; I’ve done a lot of research, and it says that plastic containers should be used for storage. If it’s PP, there shouldn’t be any problems, right? What was the result of corrosion that the original poster experienced?
Those lined with PTFE have not been in use for long; the polypropylene ones have also not been used for very long.
Pipes use 1Cr18Ni9Ti (321); storage tanks use 0Cr18Ni10Ti or 0Cr18Ni11Ti; valves use steel lined with PTFE
The packaging drums brought by the manufacturer can also get corroded over time. Therefore, if it is used frequently, it is recommended to use steel-lined PTFE.
It’s best not to use polypropylene; although it is cheap, it is extremely unsafe and has a short lifespan.
