Stainless Steel 321 Flanges

The stainless steel 321 flanges is an austenitic alloy that helps in increasing the strength and easy attachment of different piping equipment. SS 321 flanges are stabilized with titanium and have outstanding resistance to intergranular corrosion. These flange are efficient in their functioning and are used in the temperature range up to 900 degrees C. The 321 stainless steel flanges have good corrosion resistance properties and are available in schedules of sch 5 to sch 160 or XXS. These flanges are efficient in connecting pipes and allow good room for easy modification and cleaning. They possess excellent mechanical properties and are durable for long periods.

The UNS S32100 weld neck flange is recognized with a long tapered hub that is useful in applications in repeated bending conditions. The flange are butt-welded and are seen across high-pressure environments. An SA182 Gr F321 slip on flange is slid on the pipe and welded on their interior or exterior to ensure a leak-proof sealing. These flanges are seen in lower pressure and temperature processes in the oil and gas industry. The 321 SS blind flange is manufactured without a bore that is used to terminate the ends of different piping equipment. They allow for modification and maintenance of the system. ASTM A182 F321 socket weld flange is typically utilized in small pipe sizes below 2 NPS. The flange are available in raised, flat, and rtj face types. These flange have similar strength as slip on flange and are welded using a single fillet weld. The DIN 1.4541 Threaded Flanges are designed with threads that allow them to join items with threads. The screwed flanges don’t require any additional welding process and are commonly used to transport air or water in the oil and gas industries.
