Wenzhou Zhongding specializes in manufacturing various slip-on flanges, loose flanges, and flat welding flanges. We offer a wide range of stock items and support custom orders. For custom inquiries, please call our hotline: 17816237895.

Product Categories:

According to the connection method and structure, stainless steel flanges are mainly divided into the following types:

Slip-On Flange: Suitable for low-pressure applications, easy to install.

Weld Neck Flange: Suitable for high-pressure and high-temperature applications, offering high strength and excellent fatigue resistance.

Blind Flange: Used to seal the end of a pipeline for easy maintenance.

Threaded Flange: Connects via threading, suitable for low-pressure, small-diameter pipelines.

Loose Flange: Used in conjunction with welding rings, suitable for applications requiring frequent disassembly.

Socket Weld Flange: Suitable for small bore high-pressure pipelines.

Product Material Selection:

Common materials for stainless steel flanges include:

304 Stainless Steel: General-purpose stainless steel with excellent corrosion resistance and machinability, suitable for most environments.

316 Stainless Steel: Contains molybdenum for enhanced corrosion resistance, particularly suitable for marine environments or chloride-containing mediums.

321 Stainless Steel: Titanium added for enhanced intercrystalline corrosion resistance, suitable for high-temperature environments.

304L/316L: Low-carbon version, less prone to intergranular corrosion after welding, suitable for applications with high welding requirements.

Product Standards:

The production and manufacturing of stainless steel flanges typically adhere to the following international or national standards:

International Standards: ANSI/ASME B16.5, DIN, EN, JIS, etc.

China Standard: GB/T 9112~9124 series, HG/T 20592~20635 series.

Product Applications:

Stainless steel flanges are widely used in the following industries:

Petroleum & Chemical Industry: Used for conveying corrosive media.

Food: Meets hygiene requirements, corrosion-resistant.

Shipbuilding: Corrosion-resistant against seawater.

Power Industry: Used in high-temperature, high-pressure pipelines.

Water Treatment: Corrosion-resistant, long service life.
