Class 300 SW Flange ASTM A105

Carbon Steel Flange Stockholder

As a leader of carbon steel flange in the manufacturing industry, Zizi supplies Class 300 SW Flange RF 3 Inch ASTM A105 125-250 AARH to Chile market.

Socket-welding flanges contain a recess in the back of the flange to receive the end of the pipe, which is attached by a fillet weld around the hub of the flange. Since socket-welding connections are not as strong as butt-welded joints, the use of this type of flange is almost always confined to NPS 4 (DN 100) and smaller sizes, and to the lower pressure ratings. Its chief advantage lies in the ease of preparation and installation
