ASME B16.47 Series A/ B Weld Neck- Blind Flange

Refer Online B16.47 Slip On Flange Dimensions in mm

ASME B16.47 flange has the various materials and grades like stainless steel, carbon steel, duplex and super duplex one. This falls under the group of large diameter steel pipe flanges. Varieties of flanges are available and all are at affordable rates. ASME B16.47 Blind Flange is in inches and the parameters consist of outside diameter, minimum thickness, raised face diameter and many more. The main intention of this flange is to block off a section of pipe or nozzle that is not used. It has holes around the perimeter.

ANSI B16.47 Flanges

ASME B16.47 Series A Class 150 Flange

B16.47 slip on flange is usually a ring placed over the pipe end with the flange face that extends from the end of the pipe. This is manufactured by using high quality raw material. Apart from this there are various other types of flanges. B16.47 Lap Joint Flange is the two component assembly consisting of stub end and has a lap joint ring flanged over it. These can be easily rotated around the stub end. ASME B16.47 Series B flange Weight depends upon the flanges that are used. Based on this, the product is manufactured.
