Seeking advice on methods for preventing corrosion of bolts in chemical enterprises
Thread Content
Our company is a chemical enterprise, and we have always struggled with the issue of corrosion protection for equipment and bolts In the past, high-temperature butter and machine oil were also used for corrosion prevention, but the results were very poor! I wonder if anyone has any good ideas for this problem!
Does the poster mean the connection bolts on the outside of the equipment?
Please specify the operating conditions, material, and corrosion characteristics of the bolts.

Even the best experts need to develop anti-corrosion plans based on the specific conditions of corrosion, and select appropriate anti-corrosion materials and construction methods. If the poster clarifies the question, experts should be able to come up with good solutions.
They are the bolts on the outside of the equipment. Because we produce active pharmaceutical ingredients, we use a great deal of basic raw materials in the synthesis process! And due to certain process and technical limitations, gas escapes from the materials during the production process! Dancing to elephant acid and the like! Corrosive factors are also present in the air within the factory area!
Most of the bolts in our company are made of carbon steel. Corrosion is mainly rusting!
The methods for preventing corrosion of equipment in various chemical industries are similar. First, it is necessary to select the appropriate materials; taking into account the corrosiveness of the medium and the overall cost, the material that offers the best balance between safety and economic efficiency should be chosen. Second, protective measures must be taken, such as the bolts mentioned by the original poster. I’ve never heard of using butter for this purpose; in chemical plants, lithium-based greases are more commonly used – essentially butter – and this can help prevent severe corrosion of the bolts. However, applying butter requires careful attention; it should be applied properly during initial installation, rather than just a little bit after installation, as there are many areas that may not be reached. Thirdly, it is necessary to establish a proper mechanism for monitoring and evaluating such measures; otherwise, relevant policies cannot be effectively implemented

Surface rusting of carbon steel bolts in industrial atmospheres is quite severe; it is recommended to replace them with stainless steel bolts.
