Pepperpot heating nozzles

[bletchmonster]

Hello. Can anyone advise on oxy propane heating nozzles, I've managed for years using a cutting nozzle for any heating jobs. But I have a job involving heating a lot of tube of various sizes 3/4" to 2" od.
I have a sapphire 3 torch with a acetylene mixer and a boc nm250 cutting torch, there seems to be various options and I wondered if anybody of experience of heating nozzles could recommend what to go for. Cheers.

I USE an oxy propane heating torch with a long neck solely for that purpose ,the rep advised the correct nozzle which is i think is rated in "btu" from memory it draws 0.7 bar of oxygen ,however i set it with a neutral flame as if i were gas welding ,it can heat 100x50 solid to red in 8-10 minutes but consumes a lot of oxygen,coping with 2" tube would be a breeze,just plan your placing/handling techniques in advance! i think my nozzle is rated at 64,000 btu but a knowledgeable supplier will advise what size with regard to your torch /shank ,an extra long shank is a must to avoid burnt hands.
