Ceramic Degassing Tubes


Pyrotek ceramic degassing tubes eliminate included hydrogen in less processing time than open end tubes. The processing efficiency of these tubes also reduces the required amount of injected nitrogen or other inert fluxing gas. Injected gas tends to coalesce around plain tubes that are positioned vertically. Pyrotek diffusers are designed to release gas bubbles in a rising pattern, which generates separate and individual bubbles that do not collect around the tube.


  • Resistant to aluminium attack
  • Excellent resistance to thermal shock
  • Four to five times longer life than graphite tubes
  • Various designs available for different applications including Bell, "T" and "L" configurations
