- Dimensions and tolerances in accordance with ANSI/ASME B16.9, ANSI/ASME B16.25 and MSS SP-97.
- Specifications for carbon steel forgings in accordance with ASTM A105.
- This is a buttweld connection used for making 90 degree branching vessels.
- "W" dimensions shown are maximum - depending on applications, at the time of order, these dimensions may be reduced. These dimensions are to be used for layout purposes to determine any possible spacing problems. In no way should these dimensions be used to pre-cut holes prior to welding. In all cases, the fittings should be used as the template to determine size of hole in run pipe.
- Insert weldolet fittings are not available for size to size applications.
