ANSI B 16.5 Class 900 lb
Catering to the needs of diverse industries, we manufacture and export a comprehensive range of weld neck flanges. These flanges are fabricated by us using high grade materials, procured from the reputed vendors of the markets. Our range of flanges is used to weld the joint to provide extra strength. They can be used in high-pressure as well as extreme temperature applications.
Our range of ANSI B 16.5 Class 900 lb Weld-neck flanges easily fit inside the pipe and provide a sturdy grip. These flanges find application in diverse industries like construction, automation, petro-chemicals etc. Highest grade of material make our flanges durable, resistant to corrosion and extreme temperature.
