Waarschuwing Greenchoice zijn boeven

Waarschuwing Greenchoice zijn boeven. Ons 3 jarig contract loopt af. Ik kom er net achter dat we van € 286 per maand naar € 988,- energiekosten per maand zijn gegaan. (Variabel = een kwartaal tarief). Een vast contract voor 1/2 jaar is € 688,-. Dat scheelt maar liefst €3600 per jaar. Als je niet oplet naaien ze je erbij. Wat een boeven…..
Ik had gehoopt op meer Corporate Social Responsibility bij Greenchoice. Jammer… #misbruikmakenvandesituatie

Pitting and Corrosion in Welds

A weld, or right next to it, often corrodes earlier because of the electrochemical differences in the material, due to different alloying elements, larger precipitations, coarser grain structures, bad welding/backing gas settings, wrong filler material, lack of passivation or combinations thereof.

I thought that also the magnitude and propensity of the corrosion are seemingly higher in welds than in plates and sheets due to the higher stored energy in the microstructure”. But after consultation with experts the top part of this text is of greater influence in forming pitting and starting corrosion in or close to welds.

Some scrubber manufacters do offer periodic scrubber passivation restoration. Wink, wink, nuts, nuts….. we can be of help!

More learnings: improvising on anchorage fails…. Building a argon purge chamber to weld a Stainless 316 cargo compressor using a flavoured condom as an inflatable bladder won’t work. Nor does a latex glove..
