[Volkan Ozguz]

İ after with Prof. Karulkar. This particular case gorevde doesn't provide any issues. There is a certified seller of PVDF piping in Turkey.

One has to be careful in providing answers  to technology questions in such open forums because the disclosed material may be protected by laws and policies, and the disclosure may have unintended consequences.   Of course this does not diminish the usefulness of the mtl.mit forum.  All the members of the forum have to reminded of its  "totally open" nature  and the ineffectiveness of the proprietary and/or confidential  caveats.

>> Dear Jeff
>> Thanks for the reply. You are right. The material proposed to us is HarvellXT. I will provide a ratioed price analysis as soon as it becomes available. I would like to place a disclaimer here. Some materials and services readily available at the US are surprisingly difficult to get here. I can find the most sophisticated LED lighting panels for example. But DI water piping was an "adventure" . Therefore the prices may not reflect the situation in USA.
