Fusion Bonded Epoxy Coated Steel Pipe

Fusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy-based powder coating that is widely used to protect steel pipe used in pipeline construction from corrosion. It is also commonly used to protect reinforcing bars  and on a wide variety of piping connections, valves etc.FBE coatings are thermoset polymer coatings.[3] They come under the category of protective coatings in paints and coating nomenclature. The name fusion-bond epoxy is due to resigning cross-link and the application method, which is different from a conventional paint. 

The resin and hardener components in the dry powder FBE stock remain unreacted at normal storage conditions. At typical coating application temperatures, usually in the range of 180 to 250 °C (356 to 482 °F), the contents of the powder melt and transform to a liquid form. The liquid FBE film wets and flows onto the steel surface on which it is applied, and soon becomes a solid coating by chemical cross-linking, assisted by heat. This process is known as “fusion bonding”. The chemical cross-linking reaction taking place in this case is irreversible. Once the curing takes place, the coating cannot be returned to its original form by any means. Application of further heating will not “melt” the coating and thus it is known as a “thermoset” coating.For more information,welcome to Contact Us.

The constituents of an Epoxy Coating includes a resin as well as a polyamine hardener. The polyamine hardener is also referred to as a catalyst. Once both the resin and hardener have been mixed, they engage in a chemical reaction which results in the formation of cross-links between the elements, once the mixture has been cured. A fully cured product results in an Epoxy Coated Pipe is a strong and rigid type of plastic coating with copious levels of sought-after mechanical properties. Epoxy coatings are distinguished for their exceptional mechanical characteristics. The epoxy coated ductile iron pipe exhibits mechanical properties such as hardness & durability, in addition to abrasion resistance, impact & chemical resistance.

The corrosion resistance properties of an Epoxy Coated Carbon Steel Pipe to attack from chemicals, for instance, those ascertained in oils, cleaners or bleach, make epoxy coatings a popular protective medium, especially in applications involving the automotive industry. Extensively, the use of a fusion bonded epoxy coated carbon steel pipe in the oil & gas as well as the water/wastewater industry. These products aid in the protection of assets from corrosion in these industries. Besides being a non-toxic coating, the epoxy coated steel gas pipe has a smooth surface, thus making for an easy to clean and maintain the product. Another benefit of using epoxy coated black iron pipe is that they tend to withstand extreme temperature settings, as they are unaffected by heat up to a temperature of 390 °F while being resistant to water.

Features of Fusion Bonded Epoxy Coated Steel Pipe

1. FBE coating is resistant to corrosion and chemical corrosion

2. FBE coating has strong adhesion to steel, complete film, soil stress resistance and good wear resistance.

3. FBE coating prolongs the service life of steel pipe.

4. FBE coating can be used for external anticorrosion of buried or underwater steel pipe installations with operating temperature of -30~100℃.

5. On the other hand, FBE steel pipe has the disadvantage of poor resistance to mechanical damage and poor resistance to moisture and heat.

6. It has high resistance to cathodic disbondment

7. FBE coating increases the life span of steel pipes providing a constant performance throughout its life span.

8. The FBE coating has high bond strength and bond firmly to mild steel pipe surface.

The Importance of Fusion Bond Pipe

Pipe and piping is an essential component for many businesses, especially the OCTG industry. Carbon steel pipe is commonly used in a wide range of applications and because steel is subject to oxidation and corrosion, the steel must be protected. One of the most popular and cost effective ways to protect piping, involves fusion bond pipe coatings. This process provides a number of benefits and can serve many different uses.Welcome to Contact Us when you free.

DURING THE FBE PROCESS

FBE coated steel pipe is fused epoxy coated steel pipe. It is an external thermal resin used in pipes. Once the FBE coating is on the pipe surface, the FBE film provides a very hard surface with great adhesion to the pipe surface. FBE layer has uniform shape and good chemical reactivity resistance.

Fusible epoxy (FBE) coatings are used to protect steel pipes from corrosion and harmful chemicals. This is a thin film coating made of an epoxy resin powder material that is applied to the pipe using a special coating device that is electrostatic sprayed. These FBE coated pipes can be used in dry conditions at temperatures up to 85℃.

Although fusion bond pipe is one of the most effective and durable coatings you can use, it can fail under certain conditions. However, most cases of failure are due to improper preparation of the pipe before coating application. This is why it is essential to choose a supplier with many years of experience and a company who is a leader in their field, like Pipefun Pipe and Fitting Facility.
