The Stainless Steel Flange is an essential component in modern piping systems, ensuring secure and leak-free connections across various industries. Lianhe Valve (Wenzhou Lianhe Valve Fitting Co., Ltd.) is a trusted stainless steel flange manufacturer and supplier in China, specializing in the production, R&D, and sales of stainless steel fittings, valves, flanges, and pipes. With extensive experience serving oil and gas, chemical processing, food and beverage, and water treatment sectors, we deliver durable, precision-engineered flanges that meet international standards. Our flanges integrate seamlessly with other stainless steel components for reliable and long-lasting performance.
We offer a comprehensive selection of stainless steel flanges designed for different installation and pressure requirements. Each type is manufactured to international standards and available in multiple materials, pressure ratings, and sizes to meet diverse industrial applications.
| Flange Type | Description | Typical Applications |
| Weld Neck Flange | Features a long tapered hub for high-pressure and high-temperature systems. | Oil and gas pipelines, chemical plants. |
| Slip-On Flange | Easy to install and align; ideal for low-pressure applications. | Water treatment systems, general piping connections. |
| Blind Flange | Used to close pipeline ends or pressure vessels. | Testing, maintenance, and sealing operations. |
| Threaded Flange | Connects to pipes without welding, suitable for smaller diameter lines. | Plumbing, low-pressure systems. |
| Socket Weld Flange | Provides strong joints for small-diameter, high-pressure lines. | Industrial and instrumentation piping. |
All flange types are available in standard sizes and pressure ratings, ensuring smooth integration with other pipeline components.
Lianhe Valve manufactures ASME, DIN, and EN flanges that comply with major international standards such as ASME B16.5, DIN, EN, GB, and ASTM. Our products are made from high-quality materials including SS304, SS316, and duplex stainless steel, offering excellent corrosion resistance and mechanical strength. Each flange is precisely machined to ensure accurate dimensions and tight sealing. Compliance with these standards ensures compatibility with global piping systems and industrial requirements.
Our industrial flanges are widely used in demanding environments due to their strength and corrosion resistance. Common applications include:
Oil and gas pipelines requiring high-pressure sealing integrity.
Chemical and petrochemical plants handling corrosive substances.
Food and beverage systems requiring sanitary conditions.
Construction and water treatment projects demanding long service life.
These pipe flanges perform reliably in high-pressure, high-temperature, and corrosive conditions, making them ideal for both industrial and commercial systems.
Choosing a Stainless Steel Flange from Lianhe Valve ensures consistent quality and performance. As an ISO, CE, and ECA certified flange manufacturer, we deliver products that meet international safety and quality standards. Our flanges provide:
Outstanding corrosion and temperature resistance.

These advantages make Lianhe Valve a reliable partner for customers seeking durable and efficient flange systems worldwide.
Choosing the correct Stainless Steel Flange depends on several factors such as flange type, pressure class, material grade, and compatibility with existing piping. Use the guide below to assist in your selection:
| Selection Factor | Recommendation |
| Flange Type | Use weld neck for high pressure, slip-on for easy installation, or threaded for non-weld systems. |
| Material Grade | SS304 for general use, SS316 for superior corrosion resistance, duplex for high strength. |
| Pressure Class | Match the flange class (150–2500) with your pipeline’s pressure rating. |
| Compatibility | Ensure dimensions align with connected pipes and fittings according to ASME or DIN standards. |
