Product Description

ASME B16.5 Slip-On Flange: Precision Engineered for Reliable Pipeline Connections

When you need secure, leak-proof connections for high-pressure pipelines, the ASME B16.5 Slip-On Flange delivers unmatched performance. Designed to meet strict ASME standards, these flanges ensure seamless compatibility with global piping systems while reducing installation time and costs. At Xi’an QinSteel Trading Co., Ltd, we combine 15+ years of engineering expertise with advanced manufacturing to provide flanges that meet API, ISO, and regional certifications—perfect for oil & gas, petrochemical, and power generation projects.

Product Overview

The products simplify pipeline assembly with their easy-to-align design. They’re ideal for systems requiring frequent disassembly and offer excellent pressure tolerance (Class 150 to 2500). Available in sizes from ½" to 24", these flanges suit both standard and custom applications.

Why Our ASME B16.5 Slip-On Flanges Stand Out？

1. Rigorous Compliance & Durability

ASME-Certified Manufacturing: Every flange meets dimensional tolerances (±0.1mm) and pressure-testing protocols (200% rated pressure).
Material Versatility: Choose from carbon steel, stainless steel, or duplex alloys for ASME B16.5 Slip-On Flange corrosion resistance in sour gas, offshore, or high-temperature environments.

2. Optimized for Efficiency

Slip-On Design: Reduces welding time by 30% compared to weld-neck flanges, lowering labor costs.
Universal Facing Options: RF, FF, RTJ, M&F, and T&G facings ensure perfect sealing with gaskets and partner flanges.

3. Custom Solutions

Tailored Dimensions: Need non-standard bore sizes or thickness? Our OEM/ODM services adapt to your specs.
Pre-Assembled Kits: Order flanges with matching bolts and gaskets for faster deployment.

Applications

Oil & Gas: Refinery pipelines, wellhead systems, and LNG terminals.
Power Generation: Steam lines, turbine connections.
Water Treatment: High-pressure pump and valve assemblies.

FAQ

Q: Can you provide the products for offshore projects?

A: Yes! Our duplex steel (F51/F55) flanges include anti-corrosion coatings for saltwater environments.

Q: Are test reports included?

A: Absolutely. Each order comes with Material Test Certificates (MTC) and pressure-test records.

Q: What's the MOQ?

A: MOQ is 10 pieces for standard sizes. Bulk discounts start at 1,000 units.

Q: Do you ship to the EU?

A: Yes. Our flanges are CE/PED-certified and comply with EU pressure equipment directives.
