ISO certified ASME B16.5 forged flange manufacturer and exporter Zizi supplies good price and fast delivery for 3" socket weld flange class 600 raised face Sch40 ASTM A182 F316/L316.
Socket Weld Flange contain a shoulder on the flange inside that acts as a guide to set the depth at which the pipe is welded to the flange. 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.
