Re: POLY ETHYLENE -ALUMINUM- POLY ETHELYNE PIPES

Jamal,

PE pipe has several advantages for laboratory water:

1. easy and less costly to run (glued, not threaded, flanged or welded)
2. smoother bore and "cleaner" fittings, less chance for debris to buildup and much less opportunity for biota (microbes, bacteria) to buildup
3. less to dissolve or extract into the water, leading to contamination

Lab water use is fairly erratic, so buildup of "crud" can be more of a problem that other uses. Uniformity of quality throught the system and over extended period of times is also important.
