What is the ASME Code for blind flanges?
Blind flange dimensions are covered in ASME B16. 5 – which covers Pipe Flanges and Flanged Fittings for size NPS ½" to 24" for above NPS 26" to 60" it should be as per ASME B16. 47.
What are ANSI/ASME B16.5 Class 150 flange dimensions?
5 Class 150 butt weld flange dimensions. ANSI B16. Class 5 150 covers butt weld flange sizes from 1/2" to 24" nominal pipe size diameter with or without 1/16" raised face.
ASME B16.5 Carbon Steel Class 150 Blind Flange is a carbon steel flange that meets ASME B16.5 standards with a pressure rating of Class 150 and is used for blind end sealing. This flange is usually made of carbon steel material, which has high strength and corrosion resistance and is suitable for various industrial piping systems.
The blind flange has a simple structure and consists of a circular plate and a flange neck. It is usually used together with bolts, gaskets and other connecting parts to fasten the blind flange to the pipeline through bolts to achieve pipeline sealing. Because the blind flange has good sealing performance and can effectively prevent media leakage, it is widely used in industrial piping systems.
