I am sweating in a splice to a 3/4 copper watter line. One side of the splice sweated well, the other side will not take solder at all, it just beads up and rolls off the pipe. The two ends of the pipe and the splice had been cleaned and fluxed.
Are you sure it's really copper, on the other side ? Have you tried sanding it down, to the point that it's real shiny ? Right, you've already done that.Is there any Pipe left over, from the other side, that won't take the Solder ? If so, is there any way that you can test it, and get it much hotter than you would, the pipes that you're trying to connect, just to see if it can be forced to accept the Solder ? If it won't, then you've probably been stuck with some low quality Pipe.I hope I'm wrong, because Copper is approaching $4 per pound .
Sumitomo tires are the best. I've had them now twice on the cars that I've owned. I was not happy with Pirelli tires, pay good money for what I thought was disappointing quality. Sumitomo's are great in the wet and in the dry, they handle well and won't burn a hole in your pocket. I know they're probably not as well know as they bigger brands, but they should be!
u have to make sure all of the water is out of the pipes before u start, if there is water it will not heat properly. Once the water is all gone then the pipe will heat and the flux will flow like it supposed to.
Is there water in the pipe? Is your gas low on torch? Re sand and flux pipe if you can. Heat the pipe first on all sides then move to the coupling. It works by capillary action and will suck into the joint. But if you are mostly one the pipe it will migrate away.
Pirelli I have been thru a lot of tires in the past and experience that Pirelli are the best in grip and tread wear
