Regarding internal anti-corrosion
Thread Content
One tank, with a diameter of 2400; the main material is Q235B. It is required to apply a layer of anti-corrosion coating on the inner surface. I was wondering whether it’s possible to conduct a hydrostatic test after applying the paint Another thing is how to make painting easier. If both end caps are welded in, the space inside is limited, making it difficult to remove rust; moreover, painting releases a strong odor ； I was wondering if anyone has any better suggestions?
It’s possible to carry out processing first and then welding, but the part still needs to be processed again after welding; safety must be taken very seriously.
