Explosion protected diesel engine exhaust conditioner corrosion

Mines safety alert no. Newsflash | 11 June 2020 | Version 1

What happened?

Internal inspections of a number of exhaust conditioner inlets have shown reduced integrity over time from corrosion an/or cracking of the internal gussets that support the exhaust inlet pipe (see figure 1 below)

After the gussets crack, they no longer support the welded connection between the inlet pipe and the lid. The weld in this location, which separates the inlet exhaust gas from the outlet conditioned exhaust gas, can crack from lack of support.

Recommendations

Site Senior Executives should:  

  • Audit explosion protected engine exhaust conditioners to identify if this failure is present.
  • Consult with the OEM's or service providers to ensure that the correct maintenance procedures and replacement parts are available.
