Socket Weld Flanges
Socket weld flanges are similar in both dimensions and applications to slip on flanges. The major difference is that socket weld flanges have an internal recess in which the pipe sits. This then gives a better flow of fluid through the piping itself. As a rule, socket weld flanges are more expensive than slip on flanges due to the extra machining required to manufacture them.
Socket weld flanges also tend to be used on smaller pipelines, typically ½”NB to 3”NB for 150lb – 600lb rated flanges and ½”NB to 2.1/2”NB for 1500lb rated flanges.
