Why Metal Alloy Tubes Fail

ALL Metal Alloy Tubes Fail Eventually Due To:                      

  • Creep … causes tube deformation, distortion & rupture at high temperature > 1550°F (840°C)
  • Carburization … causes metal embrittlement and corrosion
  • Thermal Shock … tube fracture, loss of carbon control
  • Melt-Through  … premature rupture
  • Weld Failure … atmospheric leakage, loss of carbon control
  • Oxidation … causes metal scaling & flaking, possible shorting of electrical heating elements

The end results are high maintenance costs and excessive downtime. INEX Si-SiC tubes are largely immune to these failure causes.  To learn more, read Cures for Heat Treat Headaches.  This article was published in the September 2013 issue of Thermal Processing for Gear Solutions.

In addition to poor life, the heat flux of metal alloy radiant tubes is limited, just half that of INEX Si-SiC composites.
