MAPP gas for copper pipe


i have always used propane for copper pipe. but it takes an awful long time to heat 1.5" pipe ready for soldering. can MAPP gas be used to do it faster ?

Thanks

Mapp gas is much better than propane although i couldn't imagine trying to use it for 1 1/2" pipe.

Mapp gas works great. Be sure to keep the tip moving and use a wider tip if you can find one. Burnz-o-matic used to sell a home version of a mapp gas torch with different tips. I don't know if they still do...

Larger tips for "home type" torches are hard to find. Most Plumbers use an acetylene tank for more heat and a larger, but lightweight, tank. These tanks also use a long hose connected to the torch so you don't have it in your way when soldering and can also be used when you are up on a ladder 10 feet. Heating 1-1/2" copper will be a chore with a handheld torch.

Because acetylene is hotter and mapp doesn't heat up 1 1/2" as well as acetylene.
