I need help determining what kind of pipes and valves to use
Thread Content
Operating condition: ALCL3 high-temperature sublimation, which requires control via a pneumatic valve. The current pipeline (1/4-inch steel pipe coated with PTFE) is prone to blockage by black deposits due to temperature fluctuations, while the pneumatic valve (without an internal coating) is susceptible to corrosion and leakage. Solutions are sought. There should be no other volatile substances
Corrosion-induced leakage in pneumatic valves may be caused by water accumulation in the pipeline, which settles inside the valve and leads to an ALCL3 reaction. A pneumatic valve with a lining can be used, or the material can be changed.
Some effort can be put into the valves; for example, choosing fluorinated-lined ball valves. If you have any questions regarding valves, feel free to add me as a friend! Let’s explore this together
Even with ultra-dry AlCl3 and sealed pipes, is it still possible for water to accumulate?
