Can water enter natural gas main lines?
No. It cannot enter because the lines are pressurised and any hole or crack in the line will exert more pressure outwards than the water can inwards. High pressure propane lines are self sealing because the gas is so cold upon leaving a crack, it will freeze to ice and be self sealing. Water can condense on the inside of a pipe just as any other surface and the gas companies have dryers to remove this moisture. Water can enter a natural gas distribution system (a pipe). Many older systems, particularly in the North Eastern US operate below 0.5 psig. If there is an opening in the pipe, water can overcome the operating pressure and enter the pipe.
