I. Product Overview

Fusion-bonded epoxy (FBE) coated pipes are a type of pipe product in which epoxy powder is applied to the surface of steel pipes and then cured at high temperatures to form a corrosion-resistant coating.

FBE pipes are widely used in the petroleum, natural gas, municipal water supply and drainage, and chemical industries due to their excellent corrosion resistance, wear resistance, and ease of installation.

The main features of FBE-coated pipes are a robust pipe body, a dense coating, and strong corrosion resistance, which significantly extend the service life of the pipes while reducing maintenance costs. The FBE coating uses a powder curing process, which is solvent-free, environmentally friendly, and safe, making it highly suitable for modern industrial and municipal pipeline projects.

IV. Hot-melt epoxy (FBE) coated pipes storage and transportation requirements

(1) Storage requirements

Flat and dry site: Avoid muddy water, standing water, and chemical corrosive media to prevent the coating from becoming damp or contaminated.

Elevated storage: Use wooden blocks or rubber pads to isolate the pipes from the ground by ≥100 mm to prevent the coating from being compressed or scratched.

Layered stacking: Add soft pads between layers for isolation; stacking height should not exceed 3 layers (2 layers recommended for large diameters).  

Avoid direct sunlight: Prolonged high temperatures can accelerate coating aging; use shade cloth or canopies as needed.  

Maintain ventilation: Warehouses or storage yards should have good ventilation to prevent moisture buildup.

(2) Transportation requirements  

Specialized support and securing: Use soft support pads and straps when loading onto vehicles to avoid direct contact with steel wires or chains.  

Layered isolation: Insert wooden planks or rubber pads between upper and lower pipe layers to prevent rolling friction damage to the coating.  

Gentle loading and unloading: Use slings or specialized lifting equipment; do not directly suspend pipes with steel wires.

Protective Sealing: Cover pipe openings with protective caps or plates to prevent debris or moisture from entering during transportation.  

Avoid Severe Vibration: Choose smooth routes and avoid sudden braking or sharp turns during transportation.  

(3) Special Notes  

If coating damage is discovered during transportation or storage, mark the area immediately and repair before construction.  

If stored for over 6 months, inspect the coating’s appearance and for pinholes, and confirm integrity before use.

V. Common Misconceptions When Purchasing Hot-Melt Epoxy (FBE) Coated Pipes

(1) Focusing solely on price without considering standards

Many purchasers prioritize low prices while neglecting whether the product meets standards such as GB/T 23257 and ISO 21809-2, resulting in insufficient coating thickness and reduced service life.

(2) Ignoring coating thickness and performance testing  

Some products are not tested for adhesion, impact resistance, or pinholes at the factory. If procurement specifications do not include acceptance criteria, it is easy to purchase non-compliant pipes.

(3) Neglecting transportation and storage conditions  

Even if pipes are qualified at the factory, improper transportation or storage (scratches, exposure to sunlight, moisture) can significantly reduce corrosion resistance.

(4) Ignoring construction compatibility

Some purchasers only buy pipes without considering配套 processes such as on-site welding and corrosion-resistant joint sealing, resulting in reduced overall corrosion resistance after installation.

(5) Blindly applying specifications from other projects

Different projects have significant differences in medium, temperature, pressure, and environmental corrosion resistance. Directly applying FBE specifications from other projects may result in insufficient performance or cost waste.
