On the selection of materials for acidic process exhaust pipelines
Thread Content
In the fine chemical industry, what pipe materials are currently being used to handle acidic exhaust gases containing small amounts of volatile solvents? Are there any other cost-effective and practical pipe options besides steel-lined PTFE and glass-lined pipes?
PVC fiberglass-reinforced pipes can be used.
Try glass fiber reinforced plastic pipes; flexible composite pipes are also an option
With solvents present, the resin used in fiberglass-reinforced plastic pipes must be resistant to such solvents; PVC won’t work, but electrofusion pipes could be an option
Lined with PE, lined with PTFE, PTFE molded tube
Does an electrofused pipe refer to a PE pipe? Could you please provide the pipe standard number and the specific material?
What are the standards for flexible composite pipes?
“Where exactly can “non-metallic pipes” be used?
