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.
