Audited Supplier 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.
Socket weld flanges are designed for small nominal pipe sizes (≤ 4 inches, ≤ 10cm) and are common for ½ to 2-inch pipe sizes (1.3 to 5cm pipe sizes). The mechanical strength of a socket weld flange is similar to that of a slip-on flange, but the slip-on flange may use two welds.
The advantage of socket weld flanges is their simple design, they are well suited for small pipe size applications e.g. 2 inches (5cm) and below, and for non-critical applications e.g. non-hazardous systems; they are not suitable for highly erosive or corrosive systems.

Socket weld flanges are not specified in ASME class 2500 rating as per the ASME B16.5 standard.
