Socket-Weld Reducer Inserts
To minimize the possibility of cracking of the fllet welds, it is recommended that the shank portion of the reducer be withdrawn approximately .0625 in. (1.6 mm) away from the contact with the bottom of the
socket before starting the weld. Likewise, the pipe is to be kept away from contacting the bottom of the reducer socket before welding.
CLASS 3000
For use with Schedule 40 and 80 Pipe
Reducer inserts comply with MSS standard SP-79. They enable standard socket-weld fttings to
be used for making any combination of pipe line reductions quickly and economically. Socket-weld
reducer inserts serve SD D the same purpose as threaded reducing bushings with threaded fttings.
