What requirements should be followed for the corrosion protection of carbon steel components on stainless steel equipment?
Thread Content
For carbon steel components such as skirts, legs, and lugs installed on stainless steel equipment, what standard is used for applying anti-corrosion paint? Are there any specific requirements regarding the color of the paint? Is it a color similar to stainless steel, such as silver powder or silver-white? Many anti-corrosion standards or technical requirements do not specify details.
According to standards such as those of CNPC or Sinopec, it should refer to the corrosion protection of the equipment itself; some skirt bases require fire-retardant coating applied later on. As manufacturers, which standard should we follow before delivering the products?
