Do alloy steel pipes need anti-corrosion treatment?
Thread Content
As the title suggests, does the alloy steel pipe made of 15CrMoG require anti-corrosion treatment? If anyone who has used it can offer some advice, I would be extremely grateful!
It has the same anti-corrosion treatment as carbon steel on its outer surface.
Above 550 degrees Celsius, the antioxidant properties decrease, so……
The 15CrMoG alloy steel used in my installation was only provided with external insulation for the steam pipelines, while anti-corrosion treatment was applied to it for the catalyst pipelines
It has been done, with varnish applied to the outer surface.
Whether it is anti-corrosive or not has no direct relation to the alloy, right?
If corrosion resistance is required, 316L can be used directly
Pre-treatment is necessary, as the properties of this alloy remain unstable at high temperatures! ! !
Is it painted on the outside as well as the inside? ? ?
Pipes that are painted inside – are there many of those? Unless it’s a large-caliber one.
Our version also has its outer surface treated for corrosion protection.
