What is flange coating?
Flange coating can be defined as the application of a layer of material over the flange to prevent it from different factors. The coating can effectively reduce corrosion, damage and even improve the appearance of the flanges. It is one of the easiest and affordable ways of protecting the flanges. The coatings are easy to apply with the help of a brush or they can be sprayed on to the flange face. One of the best things about these coatings is that they are compatible with almost all types of metals. They dry up quickly and hence there is no long time involved. Flange coating can be used for various applications and they are readily available too.
However, there are certain disadvantages of the flange coating, like it is not able to keep the debris off the piping components. This is because the bore of the pipe is left open. Even though they might cover up for minor scratches, the flange coating will not protect the flanges from any type of mechanical impacts and also they can be scraped off easily. Also, this is not a convenient option for the long-term. The effectiveness of the flange coating depends a lot on the applicator, if the coating is not applied properly, it can cause rusting on the flanges. Thus, there are equal advantages and disadvantages of the flange coating process.

Why do we do 3lpe coating on flange?
For long distance conveyance of crude oil, natural gas, etc., the pipeline needs to be buried underground. The external surface of the pipe might get corroded due to the damp environment underground and also due to the presence of soil and water. With a 3lpe coating on the flanges, the issue can be resolved and it also enhances the durability, increasing the overall lifespan of the piping system. The 3lpe coating offers excellent resistance to wear, abrasion, alkali, acid, etc.

Types Of Epoxy Coating Used For Flanges?
The Types Of Epoxy Coating Used For Flanges are:

  • Epoxy Lined Flanges
  • Fusion Bonded Epoxy Coating Blind Flange
  • Flat Face Flange Coating
  • Flange Pe Coating
  • DN300, PN50 Underground Flange Coating

How Long Does FBE Coating Last on Flanges?
FBE is a fusion bonded epoxy coating, which is a thermosetting powder coating that has anti-corrosion properties. Due to their nature, they are considered a permanent one.

What is Flange Face Coating?
Flange face coatings are the coating of different materials applied on the flange face. They are basically of two types, with and without the rust inhibitors. The coatings that have rust inhibitors are more popular and used widely due to their added benefits. The one without inhibitors basically helps in creating barriers and keeps any type of moisture away from the flange face.

  • Layer 1: This is a corrosion-protective layer. This layer is made of fusion bonded epoxy, which provides excellent corrosion resistance. The fusion bonded epoxy adheres quite well to the blasted steel surface.
  • Layer 2: This is the copolymer sticky layer. The copolymer adhesive is a polyethylene compound grafted with maleic anhydride. This substance chemically bonds well to the fusion bonded epoxy and the top layer polyethylene.
  • Layer 3: This layer is made of polyethylene and serves as physical protection. Because copolymer adhesive and polyethylene are similar, they adhere well.

Pros

  • These coatings are quite simple to apply.
  • Rust inhibitor-containing coatings are extremely effective at preventing corrosion.
  • They tend to dry quickly.
  • Readily available and simple to obtain

Cons

  • Because the bore of the pipe is left uncovered, none of these flange face coatings keep dirt out of the piping components.
  • They also offer little impact protection.
  • Coatings are not suitable for long-term storage.
  • If the coating is not placed appropriately, a portion of the flange face may be exposed to the environment, resulting in rust.
