Heat-damaged O-ring gaskets? Burnt or charred components? No water available for a wet rag? Keeping things cool on site can be a problem for engineers …
Using a wet rag to stop heat travelling through copper when brazing, soldering and welding is the traditional method of protecting heat sensitive areas around a welding site. If a wet rag can even be found on site, the method presents issues for the engineer. A wet rag can be awkward to position and can fall off the pipe. It can dry out from the inside; attaching itself to the pipe meaning it needs to be doused. Additionally, despite the heat blocking intentions of using a wet rag, heat does transfer to components when welding.
A wet rag can create warpage and damage, as quenching the weld may harden it and make the surrounding metal more prone to cracking. Components can heat up despite using a wet rag, whereas using a heat blocking putty like the JAVAC Heat Shield, protects the pipe and keeps it cooler for longer.
Proven to block conductive heat transfer, Heat Shield Putty protects pipes, surfaces and sensitive areas from heat damage. Simple to use and reusable up to 40 times, apply the putty to the area that needs protecting; braze, solder or weld, allow to cool, peel off, remould and reuse.
