[labnetwork] PVC piping

Fri Oct 1 03:03:04 EDT 2010

HI Volkan,
I am not sure where you are, but PVDF piping and valves is an export controlled item from the USA, Germany and elsewhere and is not available without an export license. I believe it can be used to make nuclear reactors, thus the red tape.

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.

Volkan

My initial concern was with organic compounds (TOC) leaching from the PVC pipe and cement, but it appears this new material has low extractables. The other concern I have is with the smoothness of the pipe joints. Any crevices or beads in the joint would invite bacteria growth.

I did not dig too deeply into the specifications, but the following link from one supplier may be of some use:

It appears there is training required to acquire the skill set needed to properly use the system, not unlike with PVDF fusion.

I’d also be curious to see the cost difference between the two systems.

We would be very interested in results on this. We have been using PVDF on the supply side and Polypro on the return side for most Nanolab construction in the last 10 years.

Subject: [labnetwork] PVC piping

 Dear Colleagues,
There are some new classes of PVC piping (and related joining techniques) marketed for use in ultra pure water applications including 18 MOhm levels. Are there any users in our network who used similar piping materials? How do they compare to PVDF or PP piping materials? What are your assements about installation, service and long term reliability?
Thanks for your help,
Volkan
