   Use a pipe cutter instead of a saw.

   Ah, yes but that would involve buying a tool that i will never need again .....

   Any other options?

   Thanks

   Rent a pipe cutter.

   But in theory the hazard is that combustable vapors will be released as the pipe is heated.  So you could either heat the pipe and vent off the vapors before cutting or somehow keep the pipe cool while cutting.  Hard to say how much of either is enough, though (or even how serious the hazard is to begin with).

   Another option is to fill the pipe with nitrogen or CO2.

   Also note that the hazard is from an explosion in a "relatively" tightly sealed enclosure.  If there is a way to vent the pipe (eg, uncouple a union or remove a plug) within a few feet and also vent or disconnect (via valve or coupling) the rest of the pipe then the worst you'd get is a "pop".  And, of course, vent the area where you're working -- windows open, fan running.

   Fill the pipe with water and cut it any which way you have available.

   Was going to suggest about 10 other ways, but since you do not even have a pipe cutter, doubt you have a N2 or CO2 bottle or even an air compressor or shop vac or vacuum pump?

   BTW, WHY do you think you would never use a pipe cutter again, that is the easy way to go.  A HF cutter is < $10.
