What is FBE 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. 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.

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.

Types of Drilling Rigs

图片
  Water Well Drilling Machine In a broad sense,  drilling rigs  can be classified as fixed or mobile. These terms describe the ability of a drilling rig to leave the drilling site quickly when necessary. This classification is broad and there is little definition of each rig type. The land and marine classifications provide a more logical grouping of rig types. While there are more types of offshore rigs to choose from, there are more land rigs in use today. Cable tool rigs. Cable tool rigs have played a key role in the history of the drilling industry. Although not in widespread use today, these rigs accounted for about 20% of all wells drilled in the United States in 1961. Many shallow Ohio, West Virginia, and Pennsylvania wells (3,000 feet) are currently drilled by cable tool rigs. Drilling with a cable tool rig is accomplished by lifting a special drill bit and placing it into the formation. The drill column consists of a drill bit, a drill pipe, a shocker, and a rope sleeve for at

What are impact crushers used for?

图片
  Introduction: Impact crushers  play a pivotal role in various industries, serving as robust equipment designed for the efficient comminution of materials. They are widely employed in mining, construction, and recycling applications, offering a versatile solution for breaking down diverse materials into smaller, more manageable sizes. Functionality: Impact crushers are primarily used for: At their core, impact crushers are utilized for the purpose of breaking down materials through the application of impact forces. These forces can be intense and are achieved through the collision of the material with the rapidly rotating rotor or by the impact of the material against breaker plates. The primary goal is to reduce the size of the material to facilitate further processing or disposal. Significance: Origins and Evolution: The origins of impact crushers can be traced back to the early 20th century when the first prototypes emerged in the mining industry. Initially designed to handle softe

The Difference Between Concentric Reducers And Eccentric Reducers

图片
    Both   concentric reducers   and   eccentric reducers   belong to reducers and are a type of pipe fittings used to connect two pipes of different diameters to change the flow rate. But the center of the concentric reducer is on a straight line, while the center of the eccentric reducer is not on a straight line.   1. What is a reducer?   A  reducer  is a component in a piping system that changes the pipe size from a larger to a smaller diameter. A reducer allows for a change in pipe size to meet flow requirements or to adapt to existing piping.   In all systems where liquids, gases, air, etc. are transported from one point to another, the diameter of the circular piping system is likely to vary. When this happens, it's important to know how to respond. There are specific fittings on the market that can connect pipes of different sizes. If the pipes are the same diameter, just use a male fitting. However, what if you were going from a 200mm diameter pipe to a 150mm diameter pipe
