ASME B16.5 WELD NECK FLANGES SERIES A OR B, Blind Flanges, ASME B16.5 WELD NECK FLANGES SERIES A OR B latest price & specification, Weld Neck Flanges Series A or B Manufacturer in India
Valour Alloys Inc., we carry a full inventory and Supply Weld Neck Flanges Series A or B products in a variety of sizes widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability.
Both Series A and B define weld neck flanges and blind flanges in raised face type. However, Series A defines ring-type joint (RTJ) flanges from Class 300 through Class 900 within this standard while Series B does not. Series A flanges are popular for new pipeline projects or equipment.
Weld Neck Flanges are a type of flange designed to be welded to the end of a pipe, providing excellent strength and durability for high-pressure applications. These flanges are commonly used in critical industrial processes where seamless and leak-free connections are crucial. The "Series A or B" designation refers to the different dimensions and specifications of the flanges.

Weld Neck Flanges Series A or B Manufacturer

Weld Neck Flanges Series A or B Exporter
Manufacturer and Exporter of Weld Neck Flanges Series A or B Series A or B in Dimension accordance with ANSI/ASME B16.5, B 16.47 Series A & B, B16.48, BS4504, BS 10, EN-1092-1, DIN, etc. Certified with NACE, PWHT, HIC, SSC, Magnetic Particle Test, Dye Penereteration Test etc.
Design: Weld Neck Flanges have a long, tapered hub that gradually transitions into the diameter of the pipe. This design ensures a smooth and gradual transfer of stress from the flange to the pipe, reducing the risk of stress concentration and enhancing the overall strength of the joint.
Welding: These flanges are specifically designed to be welded to the pipe. The welding connection provides a strong, permanent bond, making Weld Neck Flanges suitable for high-pressure and high-temperature applications.
Series A or B: Dimensions and Specifications: The Series A and B classifications refer to the different dimensions and specifications of the flanges. These standards are established by organizations like the American National Standards Institute (ANSI) or the American Society of Mechanical Engineers (ASME).
ANSI/ASME Standards: Series A and B Weld Neck Flanges are typically classified according to ANSI/ASME B16.5 standards. Series A flanges have a larger hub diameter and a smaller outside diameter compared to Series B flanges.
Pressure Ratings: Series A and B flanges may have different pressure ratings and temperature limits, so it's important to choose the appropriate series based on the specific requirements of the application.
Selection Considerations: Pressure and Temperature: Consider the pressure and temperature requirements of the system when selecting between Series A and B flanges.
Material Compatibility: Choose flanges made from materials suitable for the intended application, considering factors such as corrosion resistance and mechanical properties.
Code Compliance: Ensure that the chosen flanges comply with relevant industry codes and standards to guarantee safety and reliability.
Weld Neck Flanges Series A and B provide robust solutions for connecting pipes in high-pressure environments, with the choice between the series depending on specific dimensional and performance requirements dictated by industry standards.
