Weldolet is the most common among all pipe olet. It is ideal for high-pressure weight application and is welded onto the outlet of the run pipe. The end is beveled to facilitate this process, and therefore the weldolet is considered a butt weld fitting. Weldolet is a branch butt weld connection fitting that is adhered to an outlet pipe to minimize stress concentrations. And it provides overall reinforcement. Normally it has the same or a higher schedule than the run pipe schedule and offers a variety of forged material grades, such as ASTM A105, A350, A182, etc.
