Abstract
An electrostatic discharge tubing segment includes a porous non-conductive interior surface and an adjacent conductive polymer portion. The conductive polymer portion is configured to transfer electrostatic charge generated by a charged fluid passing through the tubing segment to ground such that electrostatic discharge can be mitigated.
Claims13
An electrostatic discharge mitigation tubing segment comprising a porous non-conductive interior surface and a conductive portion, wherein adjacent conductive portion is configured to transfer electrostatic charge generated by a charged fluid passing through the tubing segment to ground such that electrostatic discharge can be mitigated,
- wherein the porous, non-conductive interior surface is defined by a non-conductive polymer portion and the conductive portion comprises one or more stripes of conductive polymer embedded within the non-conductive portion between an interior surface and an exterior surface of the tubing segment, and
- further comprising an outer conductive polymer layer in charge transfer contact with the one or more stripes of conductive polymer.
