Stainless Steel (SS) Body Flanges are among the most reliable and widely used components in piping and mechanical systems, providing superior durability, leak-proof connections, and excellent corrosion resistance. These flanges are extensively utilized in oil & gas, chemical processing, petrochemical, water treatment, power generation, marine, and food industries. Designed to meet international standards, Stainless Steel Body Flanges ensure high performance under extreme temperatures and pressures.
A body flange is a crucial part of pipeline and machinery systems, enabling the secure connection of pipes, valves, pumps, and other equipment. The term “body flange” often refers to a flange that forms part of a valve or pump body, ensuring a tight seal and proper alignment of connected components. With stainless steel as the material of choice, these flanges gain additional properties such as corrosion resistance, longevity, and ease of maintenance.
Grades and Materials of Stainless Steel Body Flanges
- Stainless Steel Body Flanges are manufactured in a wide range of grades to meet the diverse needs of different industries. Commonly used grades and materials include:
- Austenitic Stainless Steel Grades: SS 304, 304L, 316, 316L, 321, 347 – Known for superior corrosion resistance and weldability.
- Martensitic Stainless Steel Grades: SS 410, 420, 430 – Provide excellent hardness and wear resistance.
- Duplex Stainless Steel Grades: 2205, 2507 – Offer a combination of high strength and excellent resistance to pitting and stress corrosion cracking.
- Precipitation Hardening Grades: 17-4 PH – Used where high strength and moderate corrosion resistance are essential.
- High-Temperature Grades: SS 309, 310, 904L – Suitable for high-temperature and highly corrosive environments.
Types of Stainless Steel Body Flanges
- Body flanges come in different configurations, depending on their design and intended application:
- Weld Neck Body Flanges: Designed for high-pressure applications, they provide a smooth transition from flange to pipe.
- Slip-On Body Flanges: Easy to install and ideal for low-pressure piping systems.
- Blind Body Flanges: Used to close pipeline ends or isolate sections for maintenance.
- Socket Weld Body Flanges: Suitable for small-diameter, high-pressure systems.
- Lap Joint Body Flanges: Provide flexibility in alignment and are commonly used with stub ends.
- Threaded Body Flanges: Ideal for systems where welding is not possible.
Applications of Stainless Steel Body Flanges
- SS Body Flanges are integral to many industries due to their durability and versatility. Key applications include:
- Oil & Gas Industry: Used in pipelines, drilling rigs, and offshore platforms.
- Chemical Processing Plants: Resistant to corrosive chemicals, acids, and alkalis.
- Power Generation: Found in steam, nuclear, and thermal power plants.
- Marine Applications: Withstand harsh seawater environments.
- Food and Beverage Industry: Comply with hygiene and cleanliness standards.
- Water Treatment Facilities: Ensure reliable and leak-proof pipeline connections.
Manufacturing Standards for SS Body Flanges
Stainless Steel Body Flanges are manufactured to meet international standards, ensuring compatibility and interchangeability. Common standards include:
