Weld Purge Your Pipes at a Low Cost with Weld Purge Film®

When tubes and pipes of certain materials, such as stainless steel, titanium, nickel alloys and zirconium are welded together, it is desirable to purge the oxygen out of the inside of the weld zone to prevent it from reacting with the hot metal and causing oxidation, porosity and corrosion. Some weld purging products available include Inflatable Systems (balloons), tandem units made of rubber...
