Product Description

Flange ASME B16.47A Manufacturer | Xi 'An QinSteel Trading Co., Ltd – Global Bulk Supplier for High-Pressure Pipeline Systems

When constructing large-scale industrial piping systems, every component must meet rigorous performance standards. Flange ASME B16.47A is specifically engineered for high-pressure, large-diameter applications, making it a cornerstone of oil & gas pipelines, LNG facilities, and refinery projects. At Xi 'An QinSteel Trading Co., Ltd, we specialize in manufacturing these critical components with precision compliance to ASME B16.47 Series A standards, ensuring leak-free performance even under extreme operating conditions.

Built for Demanding Environments

Material Excellence

Our Flange ASME B16.47A products use ASTM-certified materials like A105 carbon steel, A350 LF2 for low-temperature resilience, and corrosion-resistant duplex steels (F51/F53/F55). Each batch includes Mill Test Certificates (MTCs) and complies with API 605, MSS SP-44, and EN 1092-1 standards.

Precision Engineering

Zero Leak Guarantee: Hydrostatically tested to 1.5x rated pressure.
Customization: Modify dimensions, facing types (FF/RF/RTJ), or materials like Inconel for unique project needs.
Surface Integrity: Machined per MSS SP-55 to eliminate pits or cracks.

Why Our ASME B16.47A Flanges Stand Out?

1. Speed Without Compromise

Pre-stocked raw materials let us deliver 50+ units in 15–20 days. Urgent orders? Ask about expedited CNC machining.

2. Certifications That Matter

We provide:

ASME B16.47A compliance reports
EN 10204 3.2 material traceability
NACE MR0175 for sour service
PED 2014/68/EU (Europe), IBR (India)

3. Bulk Order Expertise

Supplied 10,000+ units annually to projects in the Middle East (desert LNG plants) and Asia-Pacific (refinery expansions).

Applications

Connecting 36" pipelines in shale gas fields
High-pressure reactor manifolds in chemical plants
Subsea oil extraction systems

Quality Assurance Process

1. Material Verification: Spectrometry checks for alloy composition.

2. NDE Testing: 100% ultrasonic (UT) and radiographic (RT) inspections.

3. Dimensional Accuracy: Laser-scanned bolt holes and thickness.

Packaging & Logistics

Corrosion Protection: VCI-coated wrappers + desiccant packs.
Marine-Grade Crating: Reinforced wooden boxes for offshore shipments.

FAQ

Q: Can you customize flanges beyond standard ASME B16.47A specs?

A: Absolutely. We've delivered flanges up to 72" with reinforced hubs for subsea pipelines.

Q: What certifications come with orders?

A: You’ll receive material certs, NDE reports, and pressure test records – all compliant with ISO 9001.

Q: How do you handle urgent refinery projects?

A: Our modular production lines prioritize rush orders without sacrificing quality.

Q: Is your packaging suitable for humid climates?

A: Yes! We use humidity-controlled sealing for destinations like Southeast Asia.
