Can low pressure steam boilers be soft soldered ?

[John Horne 2Participant @johnhorne2]

I agree duncan, silver solder has huge advantages and obviously should be used on anything above small statics most of which will never get anywhere near 100psi, even my Stuart has a working pressure of only 60psi max, Mamods and the like I think run at around 40psi, that's what safety valves are for. No matter what its soldered up with, if you run it dry you will have serious problems.

I did say I wasnt sure about bigger boilers and to contact the suppliers to make sure, I was only offering a better option for smaller stuff which the OP was asking about.

I've been reading this thread about soft solder and silver solder on boilers.

I've got all the materials needed for a boiler of 4inch dial.

I was considering soft solder with rivets, but would prefer silver solder without rivets.

My heat sorce is a Map tourch, will this give me heat I need for silver solder.

If so I will go for the high melting point, I've seen on You Tube the gas torches used that roofers use for this.

Thanks Bob
