Thermoplastics at 95 degrees C is a tough situation. From historical perspective I think most autoclaves have been piped in either copper or stainless steel. I think today most people use stainless steel in aeseptic environements.<br>
<br>
There are some fiberwound epoxy pipes that can withstand these temperatures. There are some fluoropolymer or fluorpolymer lined pipes that can withstand that temperature. These are not thermoplastics. <br>
<br>
I am wondering what your desire is for thermoplastics. If it cost then not always are thermoplastics a lower cost option. Selection of material can be influenced by many factors including: desired line size, maintenance requirements, support needs, fluid composition, operating pressure and thermal cycling.<br>

I could give you some more advice if I understood more of your problems. dprice000@americanisp.net
