Haihao Group Delivers BS EN 1092-1 A105 Flanges with FBE Coating for Saudi Arabia Project
Haihao Group recently completed the production and shipment of a batch of forged steel flanges for a customer in Saudi Arabia. The order included large-diameter welding neck flanges and blind flanges manufactured from ASTM A105 forged carbon steel in accordance with BS EN 1092-1 requirements.
To enhance corrosion resistance in demanding environments, all flanges received an external Fusion Bonded Epoxy (FBE) coating with a thickness of 350 microns. The project demonstrates Haihao Group’s capability to supply high-quality BS EN 1092-1 flange products for water transmission, infrastructure, energy, and industrial pipeline systems.

Why BS EN 1092-1 Flanges Are Widely Used
The BS EN 1092-1 flange standard is one of the most commonly specified European flange standards for industrial and municipal pipeline projects.
The standard provides strict dimensional requirements, pressure classifications, and material specifications, ensuring compatibility across different piping systems and equipment manufacturers.
Key advantages include:
- Internationally recognized dimensions
- Reliable sealing performance
- Broad availability across global markets
- Compatibility with European project specifications
- Suitable for water, oil, gas, and industrial applications
For infrastructure projects in the Middle East, BS EN 1092-1 flanges are frequently selected due to their proven performance and standardization.
ASTM A105 Forged Steel for Strength and Reliability
All products in this order were manufactured from ASTM A105 forged carbon steel.
ASTM A105 remains one of the most popular flange materials because it offers:
- High mechanical strength
- Excellent machinability
- Good weldability
- Reliable pressure performance
- Cost-effective lifecycle value
The combination of ASTM A105 material and BS EN 1092-1 flange design provides dependable performance in demanding service conditions.
External FBE Coating for Corrosion Protection
A key requirement of this project was the application of external Fusion Bonded Epoxy (FBE) coating.
All flanges received a 350-micron FBE coating on external surfaces.
Benefits of FBE Coating
- Improved corrosion resistance
- Extended service life
- Enhanced durability in humid and coastal environments
- Reduced maintenance costs
- Additional protection during transportation and storage
For Saudi Arabia’s infrastructure and water projects, FBE-coated flanges help improve long-term operational reliability.
Large-Diameter Flange Manufacturing Capability
One notable feature of this shipment is the inclusion of very large flange sizes, including DN1800 and DN1200 welding neck flanges.
Manufacturing large-diameter BS EN 1092-1 flange products requires:
- Precision forging and machining
- Strict dimensional control
- Careful flange face inspection
- Consistent coating application
Haihao Group’s production facilities are equipped to manufacture both standard and customized large-diameter flanges for international projects.
Applications of FBE-Coated BS EN 1092-1 Flanges
These flange products are commonly used in:
- Water transmission pipelines
- Desalination plants
- Municipal infrastructure projects
- Industrial process systems
- Power generation facilities
- Oil and gas support systems
The combination of forged A105 steel and external FBE protection makes these flanges particularly suitable for long-term outdoor service.
Quality Assurance Throughout Production
Every BS EN 1092-1 flange supplied in this project underwent comprehensive inspection procedures.
Material Verification
Raw materials were verified to ensure compliance with ASTM A105 requirements.
Dimensional Inspection
Critical dimensions were checked against BS EN 1092-1 specifications.
Coating Inspection
