If charge build up within pipework caused by the flow of non-conducting liquids (such as solvents) over virgin PTFE is a problem, the first step to solving the problem can be the use of antistatic PTFE lined pipe The details of this material and its properties are dealt with more fully elsewhere. For the purposes of this discussion, it should be said that the antistatic version of PTFE will allow static charge to slowly migrate from the inner surface of the PTFE to the outer surface of the PTFE, and from there it will contact the steel outer housing
