Abstract
A tubing apparatus includes corrugated tubing including convolutions of peaks and valleys in the body of the tubing; an electrically conductive or semi-conductive, polymer jacket disposed along an exterior length of the corrugated tubing; wherein the jacket provides protection to the inner corrugated tubing from damage resulting from electrical arcing at levels ranging from at least 9 coulombs at a waveform of 10 microseconds×1000 microseconds.
Claims20
A tubing apparatus comprising:
- corrugated tubing including convolutions of peaks and valleys;
- an electrically conductive or semi-conductive polymer jacket disposed along an exterior length of the corrugated tubing;
- wherein the jacket includes carbon in an amount sufficient to protect the corrugated tubing from damage resulting from electrical arcing at levels of at least 9 coulombs at a waveform of 10 microseconds×1000 microseconds.
A system comprising:
- corrugated tubing including convolutions of peaks and valleys;
- an electrically conductive or semi-conductive, polymer jacket disposed along an exterior length of the corrugated tubing, the jacket including carbon in an amount sufficient to protect the corrugated tubing from damage resulting from electrical arcing at levels of at least 9 coulombs at a waveform of 10 microseconds×1000 microseconds;
- a fitting securable to the corrugated tubing;
- the fitting including a pocket for receiving the jacket.
