Internal FBE Coating Pipe

Internal FBE Coating Pipe is a steel pipe with a Fusion-Bonded Epoxy (FBE) layer applied to the inner surface. This coating provides excellent corrosion resistance, smooth fluid flow, and extended service life, making it especially suitable for transporting oil, gas, produced water, and drilling fluids. Compared to bare steel, internally coated FBE pipes significantly reduce frictional pressure losses, improve hydraulic efficiency, and protect against internal corrosion in aggressive environments.
Applicable standards include AWWA C210 / A210, ISO 21809-2, and relevant oil & gas specifications.

1. Surface Preparation

The internal steel surface is cleaned and shot-blasted to near-white metal finish (Sa 2.5–Sa 3).

Ensures optimum roughness for epoxy adhesion.

2. Pre-heating

Pipe is uniformly heated to the required temperature (typically 180–230°C).

3. Epoxy Application

Fusion-bonded epoxy powder is sprayed onto the hot internal surface.

Powder melts, flows, and fuses into a continuous film.

4. Curing & Cooling

The epoxy cures into a strong, cross-linked polymer coating.

Controlled cooling ensures adhesion and dimensional stability.

5. Inspection & Quality Control

Holiday detection, coating thickness measurement, adhesion tests.

Standards such as AWWA A210 and ISO 21809-2 followed.

• Coating Thickness: Typically 250–500 μm, depending on service requirements.
• Max. Operating Temperature: up to 95°C continuous (higher grades up to 120°C).
• Adhesion Strength: Excellent adhesion to substrate, resistant to under-film corrosion.
• Chemical Resistance: Strong resistance to hydrocarbons, saline water, H₂S, and CO₂.
• Friction Factor: Smooth surface reduces pipeline pressure drop by 15–25%.

• Oilfield Drilling: Internal FBE coating for drill pipes, protecting against drilling mud and abrasive fluids.
• Oil & Gas Transmission: Used in gathering lines, production flowlines, and transmission pipelines where sour gas or produced water is present.
• Water Pipelines: Applied in seawater injection, produced water re-injection, and municipal water transport to minimize corrosion.
• Industrial Service: Chemical plants, power stations, and process pipelines requiring clean fluid transport.

Superior Corrosion Protection – Prevents internal corrosion from crude oil, brine, gas condensates, and chemical agents.

Improved Flow Efficiency – Smooth epoxy surface reduces turbulence, lowering pumping costs and saving energy.

Extended Service Life – Significantly increases pipeline lifespan in aggressive environments.

Versatile Application – Suitable for drill pipes, oil pipes, water injection lines, and offshore pipelines.

Standard Compliance – Meets AWWA A210, ISO 21809-2, and oilfield project specifications.

Octal Pipe ensures that every Internal FBE Coating Pipe is manufactured under strict quality assurance systems, fully complying with international standards such as AWWA A210 and ISO 21809-2. Each pipe undergoes holiday detection, coating thickness measurement, adhesion strength testing, and hydrostatic pressure verification, guaranteeing consistent performance and corrosion resistance.

In addition, we provide flexible supply capability to meet different project requirements:

• Custom coating thickness according to service conditions.
• Wide size range from small-diameter drill pipes to large-diameter transmission lines.
