Can PPR or UPVC pipes be used for freezing conditions of minus 10 degrees? Could you recommend a better diaphragm pump?

I have several rotary evaporators in my room; the refrigerant used is ethylene glycol, and the lowest temperature reached is around minus 10 degrees. Can ethylene glycol be used for these pipes?
