Chad Fabry Posted May 29, 2012 Report Share Posted May 29, 2012 I've never seen it before. It says "DWV" on most of the pieces. There were like 4 or 5 different shades of grey ranging from electrical grey to almost white.

Tom Raymond Posted May 29, 2012 Report Share Posted May 29, 2012 It's from spillage at the extrusion plant. Pellets the size of grains of kosher salt come in bags the size of refrigerators. They get dumped into giant hoppers, dropped into screws and forced through dies into what ever part is being made that day. Lots of pellets get spilled. They can either be scrapped or made into odd colored parts. Everyone should visit a vinyl extrusion plant at least once. There is a fog of fine vinyl particles in the air, the stench of melting plastics, the screech of the cut off saws, and watching the parts extrude is as much fun as watching paint dry.

I visited a PEX plant with a few of the TIJ brethern and actually found it quite exciting. Been so long ago, I can't 'member who all was there!

Marc Posted May 29, 2012 Report Share Posted May 29, 2012 Thanks Tom. I've seen it many times but never been able to explain it to inquiring clients until now. Marc Link to comment Share on other sites More sharing options...

I figured something like that. Thanks. Link to comment Share on other sites More sharing options...

I have a picture of us all somewhere - if I get a chance I post it. That was a great trip - I want to do it again. Link to comment Share on other sites More sharing options...

allseason Posted May 30, 2012 Report Share Posted May 30, 2012 The problem is that the grey pvc is to indicate to excavators that the pipe they encounter below grade contains electrical components, white pvc indicates plumbing. Link to comment Share on other sites More sharing options...

John Kogel Posted May 30, 2012 Report Share Posted May 30, 2012 Les, Mike, Mark, Randy, Ezra, me.......I know there were more...... Les isn't sure, remembers something about melting plastic, Mark recalls taking pictures, those other guys are pretty silent. My guess is a few brain cells were destroyed at the plastic plant that day. [] Link to comment Share on other sites More sharing options...
