Note:
When the pipe is seated against the bottom of the socket prior to welding, to prevent possible cracking of the fllet welds, it is recommended that the pipe be withdrawn approximately
1
⁄
16
in
(1.6mm)
away
from contact with the bottom of the socket before starting the weld.
Average of socket wall thickness around periphery shall be no less than listed values. The minimum values are permitted in localized areas.
