[labnetwork] joining long PVDF pipe runs

[Schweiger, Dennis]

Iulian,

Here's something else to consider, Spears now offers a PVC product for DI water systems.  When we did the renovation project (wet chemistry suite, and surrounding labs) here at UofM, they were very interested in getting us to try the product as a beta site for the entire University.  To sweeten the deal, they donated all of the material (valves, piping, fittings, etc.) for the entire installation.  It was a LOT of money as a donation.  We're currently generating 17.07M-ohm water at the plant, and on the far end of the loop, we're measuring it at 16.9 M-ohm.  It's not a material we would have considered for the clean room project, but for our wet chemistry suite, it works very well, and was very cost effective.  The biggest savings, other than the donation of material, was the labor to install the product.  It was roughly half the man-hours from a fused system.

By the way, you may want to look at their Lab Waste product for your drain system as well.  It's also a CPVC system that saved us quite a bit on the installation costs.

Good Morning.

We are trying to determine how to best join long runs of PVDF pipe on our ultrapure water system (we are trying to achieve Type E-1.1 per ASTM D5127).  We are aware of the following methods:
- fully welded system
- systems using flanges
- systems using unions
- systems using GF sanitary couplings with clamps

Knowing how other University Fabs do it would be very helpful in making a decision (affecting water quality, cost, and schedule) and thus your input will be much appreciated.
