Note
1) The even thickness around the socket bore shall not be less than the average value,the thickness
at partial areas can be the min.one.
2) Considering the tolerance of outside diameter of pipe,the diameters of some socket bore can be
a litle larger than the ones specified in B16.11.
3)When the sizes of the connecling pipes aren't confomed to the ones specifed in this catalog
