Gilles,
Thank you for your inquiry to the PPFA concerning your application of piping for
vacuum distillation.
For your application, ethyl
alcohol at a slight vacuum and temperature of up to 140°F, ABS and CPVC should handle the application quite well.
You may want to consider other
thermoplastics that would also handle this application such as PVC (140°F is the max, temperature limitation), Polyethylene
and Cross-linked Polyethylene (PEX) or Polyvinylidene Fluoride (PVDF).
ABS, PVC and CPVC are cementable
while the other plastics can be joined using heat fusion and, or mechanical-type joints (PEX in particular).
Please
check the PPFA/TIPS
website www.ppfahome.org/tips and click on the manufacturer’s products category to see members who offer these products. If you have further questions,
please don’t hesitate to contact us again.
Sincerely,
David A. Chasis
