Procure top-quality ASME/ASTM A182 F-316/316L/316H/316Ti Lap Joint Flanges, available in sizes from 1/2" to 72" inches, ensuring superior quality for your pipeline needs.

Stainless Steel flanges crafted from the 316 series—316, 316L, 316H, and 316Ti—embody the pinnacle of corrosion resistance and durability, making them indispensable components in critical industrial applications. Conforming to stringent ASTM A182 standards, these flanges boast impeccable quality and reliability, ensuring steadfast performance in aggressive environments such as chemical processing, marine, and pharmaceutical sectors. Their high chromium and nickel content fortifies them against corrosion, while the addition of molybdenum in 316 variants enhances their resistance to chloride-induced pitting and crevice corrosion, ensuring prolonged service life even in harsh conditions.

Engineered to meet ASME B16.5 dimensional specifications, Stainless Steel 316 series flanges offer precise fitting and seamless integration into piping systems, providing a robust solution for various industrial challenges. Their low carbon content, particularly in 316L, minimizes carbide precipitation during welding, mitigating the risk of sensitization and ensuring superior weldability and corrosion resistance in heat-affected zones. Moreover, the titanium alloying element in 316Ti flanges imparts exceptional resistance to intergranular corrosion at elevated temperatures, making them well-suited for applications in heat exchangers, boilers, and other high-temperature environments.

The versatility and reliability of Stainless Steel 316 series flanges extend beyond their corrosion resistance to encompass an array of mechanical properties and applications. With their exceptional strength, ductility, and formability, these flanges find widespread use in critical industries such as oil and gas, petrochemicals, and food processing. Whether in high-pressure piping systems or extreme temperature environments, Stainless Steel 316, 316L, 316H, and 316Ti flanges stand as the epitome of performance, ensuring the integrity and efficiency of industrial operations worldwide.

01 What are the distinctions between SS 316, 316L, 316H, and 316Ti?

SS 316 stands as the standard stainless steel grade with commendable corrosion resistance and mechanical strength. On the other hand, SS 316L features a reduced carbon content, enhancing its corrosion resistance, particularly in welded configurations.
SS 316H is distinguished by its heightened carbon content, rendering it suitable for applications necessitating elevated mechanical properties at high temperatures.
SS 316Ti, containing titanium, exhibits resistance against chromium carbide precipitation, making it well-suited for use in environments with elevated temperatures.

02 How does one determine the appropriate grade of SS 316 Flange for a given application?

The selection process hinges on several factors including operational parameters such as temperature, pressure, and chemical environment.
For general-purpose applications with moderate temperature and corrosive conditions, SS 316 or 316L variants suffice.
In scenarios requiring high-temperature resistance coupled with elevated mechanical properties, SS 316H Flanges are recommended.
SS 316Ti Flanges find favor in environments susceptible to sensitization or intergranular corrosion owing to their titanium content.

03 Can SS 316 Flanges withstand high-pressure environments?

SS 316 Flanges are engineered to withstand considerable pressure levels typical in various industrial applications. However, it's essential to adhere to recommended pressure ratings specified by the manufacturer and industry standards. Proper installation, bolt tightening, and gasket selection are critical factors in ensuring the integrity of flange joints under high-pressure conditions.
