9/10/2014 · To be honest they run great on 1-2 psi. I wouldn't say silver soldering is a waste just because the boiler operates at low pressure, it means you're highly unlikely to damage it if you boil it dry, will probably last longer than a soft soldered one and for at least 650 I'd

5/4/2017 · I know this is an old thread but I only just joined for smaller boilers you might want to consider Comsol, it's not as good as silver solder, but much better than ordinary soft solder The data sheet for Comsol gives melting point as 296 C, even superheated steam only gets to around 130 C so comsol is well within acceptable safety margins temperature wise.

Polly Model Engineering: Technical Notes

Briefly for boilers up to about 5"dia x 10" high a 1.25" burner will suffice, for 5" gauge loco boilers use a 2.5" burner and for really big boilers get 2 of the 2.5" burners. Oxy Actylene is to be avoided unless one is really skilled in it's use, even then only a soft white flame is used to avoid burning the parent metals.
