Can F4-lined pipes be used in strong acid pipelines? Is there any temperature requirement for concentrated sulfuric acid above 90%?
Pipes lined with F4 can be used for concentrated sulfuric acid, as well as high-temperature concentrated sulfuric acid. The main thing is to ensure the quality of Shenli.
F4 materials can be used in strong acids and alkalis of any concentration at temperatures below 200 degrees without any problem.
It can be used, but you have to check the quality
For concentrated acid and dilute acid, negative pressure must be avoided.
Why do strong acid pipelines in dry suction systems not use steel-lined PTFE pipes? What are the disadvantages?
Steel-lined PTFE pipes are relatively expensive and have restrictions on use. They cannot be operated under negative pressure, otherwise the lining will fall off.
