Hi Richard,
Has the piping been certified to deliver E-1 grade water yet? Or some other specific criteria? Everyone is interested to know if your material and method are adequate....
Best Regards,

Hi,

We are just finishing construction on a new cleanroom here at Draper. Our DI water piping is natural polypropylene, IR fusion welded with butt joints. We felt that this could provide us a DI system that meets the semiconductor standard. The pipe supplier is Asahi/America. The pipe is weld in an on-site cleanroom then the pieces are assembled in the air on overhead racks resting in a pipe trough. To make assembly a little easier the pipe sections are joined by clamps.

This was done to keep assembly cost reasonable and purity sufficient for our operation.

Hopes this helps.

Rick

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.
