ASTM B366 HASTELLOY C22 INSERT WELDOLET NICKEL ALLOY FORGED OLETS FITTING B16.11

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 are

bevelled to facilitate this process， and therefore the weldolet is consider a

butt weld fitting.Weldolet is a branch butt weld connection fitting that is

adhered to outlet pipe to minimizes 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.
