What type of pipe can withstand acids and solvents at a temperature of around 70 degrees?

Polypropylene was used before, but the pipes would bend after some time of use. Liner Fourfo is too expensive, and the pipes are DN40. This post was last edited by chinazwr on 2009-1-5 at 17:48.]
With PTFE tubing, 70 degrees is no problem
Steel-lined PP is cheaper than steel-lined PTFE; it provides resistance to acids, most solvents, and temperatures up to 70°C. Steel-lined pipes solve the issue of strength, but they are more expensive. It is necessary to measure the dimensions carefully during installation. PP resists most solvents, but it may swell in the presence of some highly soluble solvents. It is advisable to consult a corrosion manual or conduct patch tests before making a choice. Fiberglass-reinforced plastics can also be considered; those made from epoxy, furan, or vinyl resins are resistant to acids and temperatures up to 70°C, while their resistance to solvents requires checking the properties of the resin or conducting patch tests.
Those with a steel lining and PE coating should also work well

The steel-reinforced plastic composite pipe is resistant to acids and solvents, with a temperature tolerance of 80 degrees; please refer to this information.
