Dear All
Do you have any sketch in reference documents that related to welding of Olets for interpretation of the following subject?
The welding of weldolets, sockolets and threadolets shall have a throat section that achieves the full strength requirements of the o-Iet rating and is profiled to avoid stress concentration.The weld profile in the longitudinal and transverse plane shall be a little thicker than a projection of the o-Iet weld preparation and extend intersect the pipe or vessel surface with an as-welded concave finish, radius about 10mm. For the transverse plane on near equal diameter run pipe, the weld profile provides a flat as welded surface from the o-Iet to the run pipe without extending to the 3 o'clock line on the run pipe.Unless approved by COMPANY, the weld section in all places shall exceed the branch pipe thickness.
Regards
