I pretty sure PTFE will have a lower heat transfer than most if not all metals. The idea is to have the highest transfer possible to keep costs down. That said, using Hastelloy would be expensive any way, so our idea at present is to construct the system with titanium and live with the fact...
Your first link may be something, the other two show the construction as stainless coated with PTFE. We know in our company how good PTFE can be regarding temperatures and resistancy to chemicals, however it is not tough and durable enough as a thin coating. Sometimes products have contact...
Tanks are made of PP polypropylene and are ideal it that respect as PP has a lower heat transfer coefficient than titanium. We want to heat the bathes with this system so the more heat transfer the better.
As electrical heating of electro-galvanising bathes is waiting for an accident to happen and burn the works down we will be using metal tubes on the bottom of our process bathes. Through these will flow fluid (water) from a heat-exchanger. Therefore a high grade plastic such as PVDF is out due...
We have one of those little devices, it is called a Tolerator and is still up to date if I'm correct.
Unfortunatly if there is nothing on the technical drawing, then one cannot really give tolerances other than say 10mm wil be 9.5mm to 10.5mm.
Do you have the drawing, or can you contact someone...
