Product Description

Flange BS 4504 Manufacturer | Reliable Supplier with Large Inventory & Fast Delivery

When sourcing Flange BS 4504 components for high-pressure pipeline systems, you need a partner that combines precision engineering with rapid delivery. At Xi’An QinSteel Trading Co., Ltd, we specialize in manufacturing BS 4504-compliant flanges designed to meet British and international standards. With a large inventory of DN 10 to DN 4000 flanges and ISO 9001-certified processes, we ensure your projects stay on schedule without compromising quality.

Product Overview: BS 4504 Flanges

The products are engineered for durability and performance in demanding environments like oil & gas, chemical plants, and water treatment facilities. These flanges adhere to strict dimensional tolerances and pressure ratings (PN 6 to PN 40), ensuring leak-proof connections across diverse applications.

Why Our BS 4504 Flanges Stand Out?

1. Compliance You Can Trust

Every flange is manufactured to BS 4504 standards, with material certifications and hydrostatic testing reports provided. Our GMP-certified facility ensures consistent quality, whether you need standard PN 10 flanges or custom RTJ-faced designs.

2. Rapid Delivery, Zero Delays

With over 50,000 units in stock, we ship 85% of orders within 7–10 days—even for urgent requests. Our logistics network covers Europe, the Middle East, and Asia-Pacific, with secure wooden-crate packaging to prevent transit damage.

3. Tailored Solutions for Complex Needs

Need flanges in duplex stainless steel (F51/F53) or non-standard sizes? Our R&D team provides OEM support for Flange BS 4504, leveraging CNC machining and automated forging to deliver prototypes in 15 days.

4. Cost-Effective Bulk Orders

Enjoy competitive pricing with volume discounts on orders above 5,000 units. We also offer kitted solutions (flanges + bolts/gaskets) to simplify procurement.

Applications Across Industries

Oil & Gas: High-pressure pipelines requiring PN 40-rated WN flanges.
Water Treatment: Corrosion-resistant A350 LF2 flanges for desalination plants.
Power Generation: Heat-treated A182 F11 flanges for steam systems.

Quality Assurance Process

1. Material Testing: Verify chemical composition and tensile strength.

2. Dimensional Checks: Laser scanning for face flatness and bore alignment.

3. Pressure Testing: Hydrostatic tests at 1.5x rated pressure for 20 minutes.

4. Surface Inspection: Anti-rust coatings and smooth finishes for optimal sealing.
