cutting steel pipe

If you use a sawzall cut the pipe on the exposed threads near the fittings. If the fittings are cast iron smash them with a 5lb. Sledge. The boiler can be taken apart with a sledge hammer and a wedge, make sure to disconnect the rods first.

    cutting steel pipe and cast iron boiler demo

    I need to remove some old steel steam pipe hanging in my basement. The biggest pipe is about 2 1/2 inches. Can I cut this up with a sawzall and what is the best blade to use for this. I also have a 20 year old cast iron boiler that I want to get rid off, do you think I can break the cast iron sections apart with a slegehammer because its to heavy to get up the basement stairs in one piece. Thanks

    Use a oxy-acetylene cutting rig or sawzall for piping. 14 teeth to inch metal blade. sledge hammer & wrecking bar for boiler. or call a scrap metal rubbish guy. they work for a reasonable rate---usually.

    Porta bands or plasma cutters

    it's easy to pinch and ruin saw blades if the pipe isn't supported properly.

    Rent or borrow a plasma cutter. Fast and safer then a torch. Make sure you have a supply of fresh air with plasma, or torch!

    Porta band saw is all I use. Real fast with no fumes.

    Blades

    Lenox is the only one. Only close second is Hilti. Had a contractor in to demo some 1 1/2" L copper yesterday, fried all of his Milwaukee Sawzall blades...I converted him!
  • Ditto here, lenox blades

    Won't break but do wear out a little faster. I always grab the sawzall unless it's big pipe or a steel boiler, then I go for the torch. 14 tpi is good. I used to love the torch, now I think I've sucked up enough soot for one lifetime. ;)

    I don't know about anybody else, but I LOVE demo. LOL...
