Doubling the main exhaust inlet pipe in the #egcs #scrubber adding more material will help spreading the heat and hopefully deminising corrosion under the continuous temperature fluctuations. This hottest part is in permanent contact with the cold spray water. Hot/cold/hot/cold/hot/cold
A quick and dirty #Scrubber #welding repair is in most cases penny wise pound foolish. If we only would have replaced the bracket , than without doubt and within months more severe problems would have occurred. Zoom in !! look at the improper penetration weld (cause) and material fatique cracks (effect)caused by the vibration of the ship.
