Weldolet is most common and economical of all branch connections, it is welded to the main run pipe (larger size) and connceted to the branch pipe (small size). The shape of the Weldolet ensures little stress concentration on the branched pipe, providing an integral reinforcement.
Branch outlet pipe fittings are providing an outlet from a larger pipe to a smaller one. They are used to instead of connected fittings such as reducing tees, reinforcing plates, and reinforced pipe sections.
There are many types based on the varity piping connected methods that weldolet, thredolet, sockolet, latrolet, elbolet, nipolet, sweepolet and flangolet. Why they are popular, because its outstanding advantages, such as safety, reliability, low cost and simple construction.
