Protective tubing apparatus for electrical arcing
A recently granted patent (Publication Number: US11994241B2) discloses a tubing apparatus designed to protect corrugated tubing from damage caused by electrical arcing. The apparatus includes a corrugated tubing with an electrically conductive or semi-conductive polymer jacket containing carbon to shield the tubing from electrical arcing levels of at least 9 coulombs at a specific waveform. The jacket, ranging from 1mm to 5mm in thickness, can also incorporate fire retardant properties for added safety. The patent further details variations in jacket composition, layering, resistivity, embrittleness resistance, and hardness to meet specific performance standards.
Moreover, the patent describes a system incorporating the tubing apparatus with a fitting designed to secure the corrugated tubing. The fitting includes a pocket for accommodating the jacket and features a nut, gap ring, and body with a pointed annular sealing edge for effective sealing. The system's design parameters, including angles between body surfaces, sealing surface concavity, and metal-to-metal sealing, adhere to industry standards such as ANSI LC-1 for fuel gas piping systems utilizing corrugated stainless steel tubing. This innovative system provides a comprehensive solution for protecting corrugated tubing from electrical arcing damage while ensuring secure and efficient sealing for various applications.
