FBE Coated Pipe | Epoxy Coated Steel Pipe | Anti-corrosion Epoxy Powder Pipe | Double Layer FBE Coating Pipe
FBE (Fusion Bond Epoxy) Coated Pipe: Detailed Specifications and Features
FBE-coated pipes are a type of epoxy-coated, carbon steel pipe. This coating manifests as an external, heat resin used for pipes, applied as a dry powder at a thickness of 400-600 microns onto the heated surface of the pipe. Once applied, the FBE film forms an extremely hard surface with excellent adhesion to the pipe’s surface. The FBE layer is even and exhibits good resistance to chemical reactions.
Specifications and Applications
The specifications of these pipes are as follows:
- Outer Diameter: 20mm~3600mm
- Wall Thickness: 1mm~80mm
- Length: Random Length, Fixed Length, SRL, DRL
These pipes are commonly used in natural gas, petroleum, water, sewage, and pipe systems.
Coating and Surface Details
The coating standard for these pipes follows DIN 30670, DIN 30671, DIN 30678, SY/T0413-2002, and CAN/CSA-Z245.21. The pipe type includes Submerged Arc Welded (LSAW/SSAW) and Electric Resistance Welded. The surface can have either a single layer or double layer FBE anti-corrosive coating powder (200um~800um). The ends can be plain, beveled, or threaded with couplings or sockets. Plastic caps and steel rings are provided, if possible.
The pipes are packed with waterproof paper wrapping, steel strips bundling, and two tags on each bundle.
Coating Process
Steel pipes undergo shot blasting and intermediate frequency preheating before painting. Subsequently, the epoxy powder coating is sprayed on the surface of the heated pipe products by an electrostatic spraying method. This coating fuses, bonds to the steel pipe surface, and solidifies to form a coating. Typically, FBE coating has a one-step film-forming structure.
Features and Limitations
FBE-coated pipes have several features:
- Corrosion and chemical resistance
- Strong adhesion to steel, film integrity, soil stress, and wear resistance
- Increased lifespan of steel pipes
- Suitable for external corrosion protection of buried or underwater steel pipe installations with operating temperatures of -30~100 °c
However, FBE steel pipes have limitations, as they exhibit poor resistance to mechanical damage and heat and humidity.
Additional Coating Types
We also offer Single-layer Anti-corrosion Epoxy Powder Pipes and Double Layer FBE Coating Pipes.
Single-layer Anti-corrosion Epoxy Powder Pipe uses materials like Epoxy Powder, Adhesion, Polyethylene or Polypropylene, and Cement Inside. These pipes adhere to the API 5L (PSL1, PSL2); GB/T 9711.1 standards.
Double Layer FBE Coating Pipes consist of an FBE base coat and a modified FBE top coat. The performance characteristics of this system, demonstrated through laboratory and field application tests, show high bonding strength, high resistance to cathodic peeling, low water absorption, and good high-temperature resistance.

Corrosion prevention of pipes refers to measures to slow down or prevent corrosion and deterioration of pipes under the chemical or electrochemical action of the internal and external media or by the metabolic activities of microorganisms.
A concrete coated pipe, also known as a concrete weight coating pipe (CWC pipe), is a steel pipe that has been externally coated with concrete. The concrete coating consists of a mixture of cement, aggregates, reinforced steel mesh, and water. The purpose of this coating is to provide strong downward force protection or negative buoyancy for the pipelines. These pipes are commonly used in sub-sea (submarine) pipelines, as the concrete coating adds the necessary weight to withstand the pressure of seawater.
FBE coating steel pipe is fusion bonded epoxy coating steel pipe.It is a kind of external heat resin used for pipes.With a form of dry powder at thickness 400-600 microns on to the heated surface of pipe.Once the FBE coated on the pipe surface,the FBE film provides an extremely hard surface with great adhesion to the surface of pipe.The FBE layer in a even form and have good resistance to the chemical reaction.
Electric Fusion Welding (EFW steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the workpiece so that the workpiece leaving the melt, the formation of the weld. It is mainly used for welding dissimilar steel welding sheet or which high power density, metal weldment can rapidly heated to high temperatures, which can melt any refractory metals and alloys. Deep penetration welding fast, heat-affected zone is extremely small, so small performance impact on the joints, the joint almost no distortion. But it has a requirement on a special welding room because welding using X-rays.
3PE, which stands for "Three-Layer Polyethylene," is a common coating used to protect steel pipes from corrosion and extend their service life, especially in applications where the pipes are exposed to harsh environments, such as in the oil and gas industry
