High-Quality 304 Flat Welding Stainless Steel Flange

Precision Stainless Steel Flanges for Industrial Applications – High-Performance, Corrosion-Resistant Solutions

Engineered for durability and precision, our stainless steel flanges are manufactured from top-tier alloys including 304, 316, and 316L grades, offering exceptional resistance to harsh environments. These components are ideal for critical connections in fluid handling systems across oil and gas, chemical processing, power generation, and automotive engineering. With tight tolerance machining at ±0.05mm via CNC technology, each flange ensures reliable sealing performance under high pressure and extreme temperature conditions.

Our product line includes welding neck, slip-on, and blind flanges ranging from 1/2 inch to 48 inches in diameter, with pressure classes from Class 150 up to Class 2500. Designed for seamless integration with stainless steel extrusion profiles and motor housing assemblies, these flanges meet international standards such as ASME B16.5 and DIN specifications. Additional Sheet Metal Parts like gaskets, brackets, and custom fittings complement the system, enabling full-scale industrial solutions tailored to unique operational needs.

Key features include electropolished or passivated surface finishes that enhance corrosion resistance, material certifications (MTC) for traceability, third-party quality inspections, and flexible global shipping with just-in-time delivery options. Whether you require standard configurations or custom-engineered designs for hydraulic systems, engine casings, or exhaust manifolds, we provide scalable manufacturing support to match your project’s technical demands.

These flanges are widely used in demanding sectors where reliability, longevity, and safety are non-negotiable. In offshore drilling platforms, chemical reactors, steam turbines, and high-performance vehicle components such as turbochargers and catalytic converters, they deliver consistent performance over extended service life. Their compatibility with both metric and imperial sizing makes them suitable for international projects requiring cross-border compliance and interoperability.

Customers appreciate the attention to detail, robust construction, and adherence to global industry norms. Many have reported reduced downtime due to improved joint integrity and fewer maintenance interventions. The combination of precise tolerances, certified materials, and standardized testing protocols has made our flanges a trusted choice among engineers and procurement managers worldwide.

Common inquiries often revolve around material selection for specific media exposure, installation methods for different flange types, and how to ensure long-term leak-free operation. Our team provides expert guidance on choosing between weld neck and slip-on styles based on stress requirements, recommends appropriate gasket materials for various fluids, and supports proper alignment during assembly to maximize system efficiency. Additionally, understanding the differences between Class 150 and Class 2500 ratings helps users select the right pressure class for their application—whether it's low-pressure coolant lines or high-stress pipeline networks.
