About SS 309 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.

Versatile Connection Options

SS 309 Flanges are designed for a variety of piping requirements, offered in several face (RF, FF, RTJ) and end types (Slip-On, Weld Neck, Socket Weld, Blind, Lap Joint, Threaded). This flexibility ensures seamless integration in both welded and bolted assemblies, accommodating standard or custom dimensions to suit project-specific needs in diverse industries.

Exceptional Performance at High Temperatures

Manufactured from SS 309 stainless steel, these flanges demonstrate outstanding heat resistance up to 1000C. Their excellent corrosion and oxidation resistance make them suitable for use in harsh environments such as petrochemical plants and thermal power stations, consistently ensuring reliability and longevity under extreme conditions.

Quality Assurance and Export-Ready Packaging

Each flange is tested and certified to EN 10204/3.1 or 3.2 standards, assuring superior material quality and traceability. Finishes available include bright, matte, polished, or smooth surfaces. Product shipments are securely packed in export-worthy wooden boxes, minimizing risk of damage during global transportation.

FAQ's of SS 309 Flanges:

Q: How are SS 309 flanges typically installed in industrial piping systems?

A: SS 309 flanges can be welded or bolted based on connection type and system requirements. For end types like Weld Neck, Slip-On, and Socket Weld, flanges are welded to pipes, ensuring leak-proof joints. For Threaded flanges, connections are made via threading, while Blind flanges are used to seal pipe ends.

Q: What face and end types are available for SS 309 flanges?

A: These flanges are offered with Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ) face types. End type options include Slip-On, Weld Neck, Socket Weld, Blind, Lap Joint, and Threaded, providing flexibility for installation in various industrial applications.

Q: When should I use SS 309 flanges in high-temperature environments?

A: SS 309 flanges are ideal when operating temperatures reach up to 1000C. Their high heat and corrosion resistance make them suitable for demanding sectors such as petrochemical processing, oil and gas, and power generation.

Q: Where are SS 309 flanges commonly used?

A: These flanges are extensively employed in industries including petrochemical, oil & gas, chemical processing, and power plants due to their reliability under high temperature and corrosive environments.

Q: What testing and certification accompany SS 309 flanges?

A: Each SS 309 flange is supplied with a test certificate complying with EN 10204/3.1 or 3.2 standards, verifying both material quality and compliance with international norms.

Q: How does the rust resistance of SS 309 flanges benefit my project?

A: The excellent rust and corrosion resistance of SS 309 flanges help to increase the operational lifespan of piping systems, reduce maintenance needs, and lower the risk of environmental contamination, especially in chemically aggressive environments.

Q: What packaging is provided for SS 309 flanges during export?

A: Flanges are packed in export-worthy wooden boxes, ensuring safe transportation and protection from damage, moisture, or contamination during shipping to domestic or international destinations.
