About SS 321 Flanges

These stainless steel flanges are fillet welded to a position and are ideal for low-pressure applications. Blind Flanges: The flanges are designed without a bore, and are used to seal vessel openings or piping systems. These flanges are ideal for piping systems or vessels that require regular inspection.

Precision Engineering for Demanding Industries

SS 321 flanges are manufactured using advanced forging techniques and are tested to meet stringent ASTM and ASME standards. Their robust design and heat resistance make them ideal for critical sectors such as oil & gas, chemical plants, power generation, and marine environments. Offering multiple connection types and end finishes, these flanges ensure a perfect fit for any industrial piping requirement.

Superior Corrosion and Heat Resistance

Engineered from premium 321 grade stainless steel, these flanges exhibit exceptional resistance to high temperatures (up to 870C) and corrosive chemicals. Their rust-proof finish, smooth polished surface, and 99% purity ensure long-lasting performance with minimal maintenance, reducing operational downtime and replacement costs in harsh operating conditions.

FAQ's of SS 321 Flanges:

Q: How are SS 321 flanges installed in industrial piping systems?

A: SS 321 flanges can be connected using welded or bolted methods, depending on the specific flange type such as Weld Neck, Slip-on, Socket Weld, or Threaded. Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) ends offer versatile installation suited to various systems.

Q: What benefits does SS 321 offer over other stainless steel grades?

A: SS 321 provides superior resistance to intergranular corrosion and heat, making it well-suited for applications with temperatures up to 870C. The addition of titanium improves stability against carbide precipitation, offering higher durability and performance compared to standard grades.

Q: Where are SS 321 flanges typically used?

A: These flanges are widely used in sectors such as oil & gas, petrochemical, chemical processing, power plants, and marine industries, where excellent corrosion and heat resistance are essential for safe and reliable operation.

Q: What packaging options are available for SS 321 flanges?

A: To ensure products arrive safely and undamaged, SS 321 flanges are packaged in durable wooden cases or pallets. This protects them from mechanical impact or environmental exposure during shipping and storage.

Q: How is the quality of SS 321 flanges maintained during manufacturing?

A: Flanges are produced using advanced forging processes, adhering to ASTM A182 / ASME SA182 standards. Stringent quality checks ensure precise dimensions, smooth polished finishes, and compliance with tolerance requirements of 0.5 mm.

Q: Can SS 321 flanges be customized for specific project requirements?

A: Yes, these flanges can be manufactured in standard sizes or customized dimensions (L*W*H) to suit unique client specifications, ensuring reliable performance in specialized applications.
