High Pressure Natural Gas Is The Best Choice For Jewelry Manufacturing
If you use acetylene, propane or low pressure natural gas from the gas utility pipe
you will be surprised by the superior performance of high-
Utility natural gas pressure is only ¼ psi in most places but your torch is designed
to work best at pressures between 3-
Cast platinum with high pressure natural gas!
Platinum melts at 3,300F and by boosting natural gas pressure to 10-
Natural gas burns at more than 5,000F but you need plenty of gas volume to put the maximum heat on the metal. Higher pressure means more gas flow and better heat transfer to platinum and all karats of gold.
Platinum casters report better results when heating with natural gas; there is less stress on the metal, less porosity and an overall better quality cast.
Work safely by using torch flashback arrestors
If your torch is connected to the utility natural gas pipe OSHA and local fire codes require you to use combination flashback arrestor check valves to protect the gas meter from a torch flashback. A check valve alone isn’t enough to be safe.
The problem is that flashback arrestor check valves need at least 1 psi gas pressure to work properly, otherwise they block gas flow.
