hdpe static charge- dry ash conveyance?

(OP)
Is it feasbile to use HDPE to convey dry fly ash underground - is there a safe way to ensure static electric charge is always and continuously grounded? copper detector tape?  Inquiring minds want to know.

RE: hdpe static charge- dry ash conveyance?

I recommend you contact the manufacturer of the hdpe pipe.  I think at one time at least one hdpe pipe "Engineering Manual" specifically "not recommended" pneumatic transport of some combustible and also non-combustible solids.  They also once mentioned that "Above grade compressed gas lines are a possible safety concern."
