Corrosion of the insulation layer on liquid ammonia spherical tanks

Corrosion of the insulation layer in liquid ammonia spheres is a common problem. For the protection of the external anti-corrosion coating on spherical tanks, there are some emerging technologies or solutions that can be considered: 1. Coating materials: Using corrosion-resistant coating materials to repair or reinforce the external anti-corrosion coating of spherical tanks can provide longer-lasting protection. For example, some polymer coatings and epoxy resin coatings have good corrosion resistance. 2. Membrane system: Using a membrane system can provide more effective corrosion protection. This system encompasses a range of layers, including primers, intermediate coats, and topcoats, with each layer having different functions and properties. Choosing the appropriate membrane system can extend the service life of spherical tanks. 3. Corrosion-resistant spraying technology: This technology can be used to quickly repair and repaint the external corrosion-resistant metal coating on liquid ammonia spheres. This technology is usually able to complete repairs in a short time, while also providing good corrosion resistance. In addition to the technologies and solutions mentioned above, it is also very important to carry out regular maintenance and inspections. Identifying and repairing defects or corrosion spots on the external protective coating in a timely manner can extend the service life of the spherical tank and ensure safe operation. Please select the appropriate technology and solution based on the actual conditions, and consult professional manufacturers or experts in liquid ammonia storage and insulation systems for advice. .

For the protective coating on the outer surface of large spherical tanks, aluminum insulation panels are the best choice; the connections between these panels should be made using 4 MM diameter aluminum rivets. On the outside, it is then tied up with 20-mm stainless steel strip.
