Product Description

Xi 'An QinSteel Trading Co., Ltd | ASME B16.20 Spiral Wound Gaskets Manufacturer & Global Supplier

When sealing high-pressure flanges in oil pipelines, chemical reactors, or power generation systems, every detail matters. At Xi 'An QinSteel, we engineer ASME B16.20 Spiral Wound Gaskets that combine precision engineering with rigorous quality control. Designed for pressures up to 5,000 PSI and temperatures from -200°C to +800°C, our gaskets ensure leak-free performance in the most demanding environments. Whether you need standard sizes or custom configurations, our solutions adhere to ASME, API, and PED standards, backed by 15+ years of industrial sealing expertise.

Why Our ASME B16.20 Spiral Wound Gaskets Stand Out?

1. Engineered for Extreme Conditions

Our spiral wound gaskets use alternating layers of stainless steel and high-purity graphite/PTFE, providing dual sealing action. The inner ring aligns with the flange, while the outer ring prevents over-compression—ideal for cyclic thermal loads in LNG terminals or offshore rigs.

2. Global Compliance, Local Support

From API 6A for oilfields to TA-Luft for low-emission plants, every gasket meets region-specific certifications. Need NACE MR0175 for sour service? We’ve got you covered.

3. Fast Turnaround, Zero Compromise

With 15,000+ pre-certified SKUs in stock, we dispatch 95% of orders within 72 hours—even for non-standard sizes like 36” Class 900 with chrome-plated rings.

4. Customization Without Complexity

Choose from 6 metal alloys, 4 filler types, and ring configurations. Our R&D team optimizes designs for hydrogen embrittlement resistance or cryogenic shrinkage.

Applications

Oil & Gas: Pipeline flanges, wellhead equipment, refinery reactors.
Power Generation: Steam turbines, boiler connections, heat recovery systems.
Petrochemical: Acid storage tanks, compressor seals, distillation columns.
LNG: Cryogenic valve assemblies, subsea manifolds.

FAQs

Q: Can you ship ASME B16.20 gaskets to Europe with PED certification?

A: Yes! Our gaskets comply with PED 2014/68/EU and include EU Declaration of Conformity.

Q: Do you offer samples for testing?

A: Absolutely. Request free samples via email—we’ll include test reports for your review.

Q: How do your gaskets handle thermal cycling?

A: The spiral wound design allows controlled compression recovery, even after 1,000+ temperature cycles.

Q: What’s the lead time for a custom 24” Class 1500 gasket?

A: 7–10 days post-design approval. We provide 3D CAD models for pre-production validation.

Q: Is your packaging suitable for humid climates?

A: Yes. We use VCI-coated anti-rust film + desiccant packs to prevent corrosion.
