Giải thích
Gas piping must be supported at the code-required spacing so it does not sag, which would stress joints, create low points that trap liquids, and risk leaks. Proper hangers and straps also keep the system secure against movement and vibration. Support spacing depends on pipe material and size and is listed in the fuel gas code.
