FLANGE SOCKET WELD 2" SCH 80/XS CLS 300 A105N RF

Socket weld flanges have a socket in which a pipe is inserted; the pipe is secured by one fillet weld located on the exterior of the flange hub. A significant disadvantage with this type of flange is that it is not considered a high-integrity joint because the weld is difficult to prove; thus socket weld flanges are only suitable for low to medium classes (≤ ASME 600). Due to their lower integrity and unsuitability for use at higher pressures, socket weld flanges almost always have flat or raised faces.
