What is the difference between a weldolet and a sockolet? Answer: The weldolet and the sockolet both have a run end and a branch end. The run end connects to the larger diameter pipe, and the branch end connects to the smaller diameter pipe. The connection to the run pipe is a fillet weld for both the weldolet and the sockolet. They differ, however, at the connection to the branch pipe. The weldolet has a bevelled end to butt weld to the branch pipe (which will also have a bevelled end), whereas the sockolet has a socket into which a plain end branch pipe is inserted, then fillet welded together.
Pipe olets Weldolet is the type of fitting used to create a branch with the smaller size of main pipe. Weldolet usually used in piping with high pressure and temperature where the connection with the joint type buttweld. The use of reinforcing pad is not required on weldolet
