Condensation in piping or tubing conveying low vapor pressure gases e.g. Tungsten Hexafluoride (WF6) or Boron Trichloride (BCl3) is prevented by applying heat to a few regions and insulating the remaining piping. Modular, half-cylinder, voltage (12-24 volts) resistive elements, electrically isolated from the piping, are applied to installed piping to provide safe regional heating.
