-----Protecting switchgear from sulfur/methane
Q. We are supplying electrical and instrumentation control systems to various industries of different environments along with the best technical solutions for the long and trouble-free working of the whole project / equipment. We are facing problem of the heavy corrosion of the electrical switchgear due to the presence of sulfur / methane in the environment particularly effluent treatment or sewage treatment plants. the relative humidity is around 60 to 90 % and temperature around 20 to 55° C. Can you suggest a practical technical solution to prevent this corrosion? We need this very urgently.

A. Hi, Sanjeev. This sounds like a typical and good application for electroless nickel plating, because it is very corrosion resistant and it makes a good contact surface (most AC adaptors and battery contacts are electroless nickel plated). That should do it. Good luck.

Q. Kindly send your expert's opinion ⇦ huh? on the corrosion due to sulfur content in the environment on the electrical switchgear without affecting the electrical conductivity parameters of the component.

A. Sorry, Sanjeev. I've suggested that you should consider trying electroless nickel plating, but I think that's as far as anyone will go. You can't get an "expert opinion" from someone who has only a limited second-hand insight into a problem, and you won't get one for free! 🙂
Good luck, but you'll need to pay a consultant if you want an expert opinion.

We are building up a room to store bare metal parts and protect from corrosion. What should be the relative humidity & temperature to be maintained in the room to protect the parts from getting rusted?
We have the restriction of keeping the relative humidity not less than 30% , since going below this level increases the cost rapidly.
Kindly give your suggestions.

Hi, Rakesh.
The lower the humidity the better, so 30% it is. And the cooler, the better. Good luck.
