Why Our ASME B16.5 Blind Flanges Stand Out？

1. Zero-Leak Assurance

Every flange undergoes hydrostatic testing at 1.5x its rated pressure, ensuring leak-proof performance even in high-stress environments like offshore platforms or chemical plants.

2. Global Compliance Made Simple

Pre-engineered to meet ASME B16.5, ISO 9001, and PED 2014/68/EU standards, our flanges come with full material traceability (MTCs) and optional third-party inspections (SGS/BV).

3. Bulk Order Readiness

With 15,000+ ASME B16.5 blind flanges in stock across global warehouses, we guarantee 72-hour delivery for urgent requirements.

4. Tailored for Complex Needs

Need non-standard sizes, duplex steel, or NACE MR0175 certification? Our OEM team creates solutions for sour gas, cryogenic, or corrosive applications.

FAQs – Your Concerns, Addressed

Q: Can I get ASME B16.5 flanges in duplex steel for offshore projects?

A: Absolutely! We supply Duplex UNS S31803/S32205 flanges with NACE MR0175 compliance.

Q: How do you ensure material authenticity?

A: Every batch includes PMI reports via XRF spectroscopy to verify grade composition.

Q: What's the lead time for 1,000+ units?

A: Standard sizes ship in 7 days. Custom orders take 4 weeks, with progress updates weekly.

Q: Do you provide export-safe packaging?

A: Yes! Flanges are crated in VCI-coated wooden boxes to prevent rust during transit.
