Why Our Flange Slip On ANSI B16.5 Stands Out？

1. ASME-Certified Durability

Manufactured to ASME B16.5 specifications, these flanges undergo rigorous hydrostatic and NDT testing to guarantee performance in extreme temperatures (-29°C to 425°C) and corrosive environments like sour gas pipelines.

2. Material Versatility

Choose from carbon steel (A105), low-temperature steel (A350 LF2), or corrosion-resistant alloys (316L, Duplex F55) to match your operational needs.

3. Easy Installation

The slip-on design simplifies alignment and reduces installation time by 30% compared to weld-neck alternatives, cutting labor costs for urgent projects.

4. Global Compliance

Compliant with API 6A, EN 1092-1, and DNV/GL marine certifications, ensuring acceptance in North America, Europe, and Asia-Pacific markets.

Applications

Oil & Gas: High-pressure pipelines, refinery systems (API 6A compliant).
Power Plants: Steam lines, coolant systems (EN 1092-1, TUV-certified).
Marine Engineering: Saltwater-resistant flanges with DNV/GL approvals.
Water Treatment: NSF/ANSI 61-certified options for potable water.

Why Choose Xi’An QinSteel?

FAQ

Q: Can you provide flanges for offshore oil rigs with DNV certification?

A: Yes! Our products meet DNV/GL standards and include NACE MR0175 compliance for sour service.

Q: Do you offer anti-corrosion coatings for wastewater treatment plants?

A: Absolutely. We apply fusion-bonded epoxy (FBE) or hot-dip galvanizing per AWWA C207 requirements.

Q: How do I verify material grades before ordering?

A: Request free samples or review our MTRs—each batch is traceable to its melt source.

Q: What's the MOQ for customized flanges?

A: MOQ starts at 50 units for tailored specifications.
