MAPP gas vs propane gas?

Mapp is the only way to go if you know what your doing.

Keeps everyone on site so much calmer too !
All that red makes them angry !

I hope some of you guys are not inter-changing half empty Mapp/Propane cylinders on to one torch.

I've always hated mapp. It is too hot for anything under 35mm if you are using a sure fire.
Yes it heats up quicker but to a higher temp so takes longer to cool. Time difference on a 15mm fitting must be about 2 seconds so what is the point.

I don't wear jimmy choos either :wink:

Some of the large players in the industry prohibit Mapp gas from being used by the employee's.

doesnt mapp give of a more toxic fume?

anyway, i use mapp, with a small pencil type torch up to 35mm. I dont use those carpy trigger torches unless its 28mm and outside in winter.

propane is a few seconds slower, best to learn with a small torch with propane.

propane i use primus bolted to a SF2,dont need to use anything else though i borrowed the old mans torch the other day he had mapp in it cant say i noticed any difference

I only got introduced to Mapp gas when my son was doing his apprenticeship. He learnt on it and I must say the joints were neat. He soon found that he was getting a few failed joints. He changed to a company who do not allow Mapp, Propane only. He has not had any problems since. I put this down to lower temperature and more even heat on small bore pipes. Its not about how quick you can solder its about a durable water tight system.

Think the vote is starting to swing towards Propane now! :smile:

 

[tamz]

I like the primus bottles too. A handy hammer if you are stuck:6:
I shouldn't say things like that :lol:

Seems a common thing with those who use mapp speaking to a few guys i know. Might be too much localised heating, don't know.

How about The old paraffin lamps? no only kidding, not that old.

The dirty ones have been fired up. Take a lot of polishing. Toothpaste and patience :smile:

I like Mapp because I can use a smaller flame so there's less risk of scorching stuff. Not a time thing though it's just what you're used to. I do see a lot of people burning the flux with Mapp by overheating the fittings.

 

[PlumbBobBob]

i've come across joints that were cooked longer than the sunday roast

I've got fond memories of my fathers paraffin torch flaring every now and again when you first lit it. It was a real advance when he got his Bullfinch torch and used a 3.7 cylinder of propane. Bit of a pain lugging it round roof spaces though.

 

[Nostrum]

Propane for me, no need for mapp if there's water in the pipe get it out otherwise it'll just blows hole in your solder when it turns to steam.cant remember the last time I had a soldered leak so it's doing the job just fine, plus mapp gas stinks and the customers walk in and think you've dropped your guts over the kitchen floor.

 

[Mike Jackson]

The smell is an advantage, when you've dropped your guts you can blame the gas.
